Needle roller of thrust and retainer assembly Level needle bearing AXK4565


31st July 2013 Bearing Technology 0 Comments
Level needle rollers and retainer assemblies are major components of the level needle bearing. The needle roller is kept and guided by the radial bag bag that arranges. The section of retainer has particular shapes, shape with the steel band of quench hardening. The small dimension retainer adopts the industrial plastics to make. The public errand of dividing into groups of the diameter of the high-accuracy needle roller guarantees the load diffusion is even as 0.002mm. Level needle roller and retainer assembly adopt the axle to guide. In this way, even guiding the surface and can also ...

How to maximize the life time of the bearing? (2)


28th July 2013 Bearing Technology 0 Comments
Install and dismantle prudently Choose the appropriate method of erection to be mechanical or hydraulic according to different application, bearing size and type And the tool. Here is some basic principles that a bearing is installed: 1.Don't exert and install strength in rolling the component, this is very apt to result in rolling the component and contacting the Taxi part and overloading with the base ring, thus cause the premature failure of the bearing. 2.Don't use any H hard tool such as hammer, opener,etc. Strike on the surface of the bearing directly, this will cause the cyclical ...
