1. Bearings generally use kerosene or gasoline as cleaning fluid.
 
2. Separate the washing tank into rough washing and fine washing, and put a metal mesh on the bottom of the tank to prevent the bearing from directly contacting the dirt in the washing tank.
 
3. In the rough washing tank, try to avoid rotating the bearing, use a brush to roughly remove the dirt attached to the bearing surface, and then put it in the fine washing tank.
 
4. In the fine washing tank, gently move the bearing to clean it. The cleaning oil in the fine washing tank must always be kept clean.

    1. Why do bearings have thrust clearance and expansion clearance?
     
    A) Metal materials have the properties of thermal expansion and cold contraction. When the shaft is operated at different temperature conditions, the length and diameter of the shaft will also change.
    Therefore, in order to ensure the formation of pressure oil film of thrust bearing, thrust clearance must be left.

    Considerable potential for increased functionality, economy and reliability in industrial applications is being released thanks to continuous development of rolling bearings, plain bearings and linear guidance systems. X-life is the seal of quality used by Schaeffler for products which have a considerably longer rating and operating life due to their increased basic dynamic load ratings in applications where the load and design envelope are identical. This extends maintenance intervals which leads to an improvement in “Total Cost of Ownership” and an increase in the reliability of the drive or the machine. Alternatively, the increased basic load ratings allow the bearing load to be increased without any detriment to the operating life. Or the customer can use a smaller rolling bearing.

    Under normal circumstances, INA bearings can only be used in conjunction with shafts and housings. Do you know how to use the INA bearing interference fit assembly? Someone will ask: "Isn't the interference fit assembly means putting the shaft or sleeve parts into the hole? Does the size of the shaft or sleeve and the hole fit slightly larger than the hole?" Can the INA bearing still operate well? ? Below, Eric Bearing Limited will answer your doubts based on the understanding.
    1. Why INA bearings adopt interference fit assembly
    When the load on the INA bearing rotates relative to the ring, that is, when the direction of the radial load does not change, but the ring rotates; or the ring is stationary but the load rotates around the ring, the mating surface bears The load position will undergo contact deformation, and at the same time, there will be a gap at the opposite position. As a result, the circumferences of the inner part of the mating surface and the out...    less

    The main performance indicators of lubricants
    (1) Viscosity
    Viscosity indicates the viscosity of lubricating oil. It refers to the internal frictional resistance generated when relative displacement occurs between oil molecules, and the size of this resistance is expressed by viscosity.
    There are two types of viscosity: absolute viscosity and relative viscosity. The absolute viscosity is divided into dynamic viscosity and kinematic viscosity.
    What we commonly use is kinematic viscosity. Since the viscosity of lubricating oil varies with temperature, it must be indicated at what temperature the viscosity was measured. The commonly used test temperature is 40°C, at which the viscosity is measured and used as the grade of lubricating oil.
    (2) Flash point and ignition point
    When the lubricating oil is heated under certain conditions, the evaporated oil vapor is mixed with air to reach a certain concentration when it comes into contact with the f...    less

    The relationship between bearing and load direction:
     
    Under normal circumstances, for pure radial load requirements, deep groove ball bearings or cylindrical roller bearings can be selected. If it is a thrust ball bearing, then it is only suitable for bearing a moderate amount of pure axial load. Moreover, one-way thrust ball bearings can only withstand bearing loads from one direction.
     
    If it is a two-way thrust ball bearing, or a two-way thrust angular contact bearing, then it can withstand the axial load in two directions. For example, if the bearing is subjected to combined radial and axial loads, then angular contact ball bearings or tapered roller bearings are usually used. And if it is a four-point contact ball bearing and a two-way thrust angular contact ball bearing, then it can withstand the combined load in both directions with the advantage of the bearing load.

    A new rolling bearing has been developed for wind turbine gearboxes that is  not only resistant to the effects of slippage, but actually prevents slippage  from occurring in the first place.
    Rather than using conventional rolling elements, Schaeffler’s FAG tube roller  bearing incorporates three tube rollers. These tube rollers enable the bearing  to rotate without slippage under all load conditions. At the same time, the load  rating and rating life are unaffected.   
    Slippage is detrimental to rolling bearings; the life and performance of a  rolling bearing will suffer if it is overloaded or under-loaded. This is because  rolling bearings are designed with a minimum load requirement in order to  function optimally. If this minimum load is not met, slippage will occur. This  means that the rolling elements not only rotate, but also slide on the bearing  raceways. Eventually, this can lead...    less

    IKO main bearing bearing sliding fault is mainly manifested in the location (typical location)
    Example: The working surface of the double half inner ring angular contact ball bearing has slippage failure
    Slippage generally occurs on a half-ring raceway of a double-half ring, and there is obvious tailing phenomenon, and one third of the spherical surface of the rolling element of the faulty bearing is discolored. Of course, there are also wide and narrow half-rings that have slippage at the same time, and there are also cases where the steel ball changes color and the inner ring does not slip.
    The main cause of IKO roller bearing skid injury is the light weight of the rotor, which does not form sufficient radial load on the bearing; the main cause of ball bearing skid injury is the change of the axial load. In addition, when the movement resistance of the rolling elements and the cage is too large, the slipping and rubbing failure will occur.

    Why pay attention to the lubrication of TIMKEN bearings
    In daily use, many people do not pay attention to the lubrication of TIMKEN bearings. They believe that lubrication has little effect on the bearing. However, this often leads to a reduction in the life of the bearing.
    So, why should we pay attention to the lubrication of TIMKEN bearings? There are the following aspects for you to answer.
    (1) The first is to lubricate all parts of the bearing to reduce the friction and wear of the bearing;
    (2) Always form an appropriate oil film on the rolling contact surface of the bearing to extend the fatigue life of the bearing;
    (3) The heat generated by friction or other reasons inside the bearing is taken away by lubrication;
    (4) Lubrication can prevent rust and dust from the bearing.
    Therefore, we must correctly recognize the importance of lubrication for bearings, improve bearing performance and reduce consumption.

This is a roller bearing with angular adjustment in X-life quality. It combines the angular adjustment capabilities of a spherical roller bearing with the axial displacement of a cylindrical or needle roller bearing. TORB bearings allow the operational reliability and cost-effectiveness of locating/non-locating bearing supports to be significantly increased. In addition to steel and rolling mills, the main areas of application also include belt and conveyor systems, paper machines (e.g. in drying cylinders), drives in marine applications, turbomachinery used in power generation (e.g. in ventilators), textile machinery, crushers, food processing machines, and agricultural machinery.

The PWG planetary screw drive is paving the way towards “smart actuators”: extremely high efficiency electromagnetic linear actuators with minimum space requirement. Applications and initial projects can be found in areas like mirror tracking systems in the solar power sector, azimuth adjustment systems in the wind power sector, feed units for sheet metal forming in the mechanical engineering sector, in sheet metal bending machines, in locking cylinders for plastic injection molding machines, in riveting and cutting devices, and in adhesive metering systems.

    Click here for more details about FAG 53326+U326 bearing Euromac, a global specialist in the design and manufacture of punching and bending machines, is benefitting from NSK ball screws, linear guides and bearings in two high-profile recent projects. In fact, Euromac has been taking advantage of NSK motion control technology since 1995 as part of a long-standing and highly successful partnership. From its headquarters in Italy, Euromac tailors machines to meet demanding customer requirements; the combination of state-of-the-art technologies and unique concepts assures users of advanced, productive and competitive products at all times. Continuous improvement and innovation is a core company ethos and represents the reason why Euromac has been able to expand its worldwide presence and achieve impressive growth since its formation in 1986. Among the latest Euromac machines to benefit from NSK motion control technologies are: the FX Bend 2550 new-generation electric press brake with 50 or 60 tonne press force, 2550 mm bend length and six-axis back-gauge; and the new-generation XT punching machine (hydraulic, hybrid or electric) with 1500 x 3000 mm capacity and a new reinforced frame. In both applications, NSK is the main supplier of ball screws, linear guides and bearings. The Euromac XT sets the bar for innovation in the punching machine arena by being available in hydraulic, hybrid and electric variants. In each type, Euromac uses a different way of moving the main punching axis. In the electric version, for example, the technology holds its own patent. Here, acceleration of 90 m/s2 and stroke of sometimes less than 10 mm, means that impact load is a constant issue.With this thought in mind, there is a clear need for high-performance, robust and reliable linear motion products. For the main punching axis on the electric Euromac XT, NSK therefore proposed its HTF SRD series ball screw with S1 ball spacers featuring grease-retaining attributes. These ball screws also make use of a special material named Tough Steel. Providing the perfect complement to the HTF SRD ball screw is the RA series linear guide with high acceleration capability.HTF SRD ball screws take advantage of an innovative end deflector recirculation system to achieve ultra-high speeds of up to 3 m/s, offering shorter cycle times and higher productivity to end users. Importantly, this high-load ball screw ensures good rotational balance, with no run-out of recirculation components, while the optimised (smooth) ball circulation methodology reduces noise by half compared with conventional systems.
