Ultra precision cylindrical roller bearing with linear expansion can be produced during the rotation by floating between roller and raceway compensation, so they are ideal floating end bearing. In addition, the radial cylindrical roller bearing also has the very high radial sex. Floating bearing almost only single bearing, so our products are widely used as a floating bearing. In addition, also used in bearing device with the following requirements: Low radial stiffness Low high axial bearing capacity Low and high precision In these applications, the axial load average by 2344 series two-way thrust angular contact ball bearings. Bearing design Standard cylindrical roller bearing with a conical hole (taper 1:12), to accurately adjust radial clearance. As a result, the radial clearance of the required or radial preloading, through conical spindle on the axial displacement. Roller hybrid ceramic roller bearings made of ceramic materials is our new product. Using the ceramic roller bearing on the friction and wear performance has improved significantly. Were reduced the amount of lubricant, reducing the temperature at the same time. Therefore, to achieve higher transmission speed, also significantly longer service life. Moreover, ceramic roller increases the static and dynamic rigidity, and due to the low thermal expansion coefficient, eliminates the increase of preloading at higher temperatures. Because of the inner and outer ring raceway and roller surface quality is very good, especially suitable for cylindrical roller bearing grease lubrication. Because there are two guard on the ring of bearing, so the distribution of the grease running-in process need to be especially careful handling.
