Ultra-precision cylindrical roller bearings

Cylindrical roller bearings themselves are divided into several categories, with common and super precision of the points. Single row bearings can only support axial load in one direction, the bearing radial load, will cause additional axial force. And the shaft or housing can limit the axial displacement in one direction. If pairs of double-install, make a pair bearing the outer ring relative, that is, wide-side end face of wide and narrow side facing narrow end. This can avoid additional axial force, but also in both directions to limit the shaft or housing within the axial clearance. Angular contact ball bearing as many as 70 kinds of variable structure. Design of high precision radial cylindrical roller bearings are loose North Seiko HRB series ultra-precision part. Pine North N10 and NN30 Seiko offers a full range of high precision products, while also providing some N19 and NNU49 series selected size products. As the rotation produced by the linear expansion can be between the roller and the floating raceway to compensate, so they are ideal for floating-side bearing. In addition, the radial cylindrical roller bearing also has a very high radial gift of.
       Floating bearing almost only single row bearings, so the products are widely used as a floating bearing. In addition, the following requirements for bearing devices: axial load capacity of radial stiffness and high precision

In these applications, the axial load from the 2344 series of two-way general thrust angular contact ball bearings to bear.

Bearing Design

Standard cylindrical roller bearings with tapered bore (taper 1:12), to accurately adjust the radial clearance. Therefore, the required radial clearance or radial preload on the spindle through the conical axial displacement to be adjusted. Roller by the ceramic material mixed ceramic roller bearing is our new products. Ceramic roller bearing friction and wear performance in a significant increase.

This to reduce the amount of lubricant, while reducing the temperature. Therefore, to achieve a higher transmission speed, life was significantly longer. Furthermore, the ceramic roller to increase the static and dynamic stiffness, and because the lower coefficient of thermal expansion, eliminating the temperature increase during the pre-set. As the inside and outside the ring raceway and roller surface quality is very good, HRB cylindrical roller bearings particularly suitable for the grease lubrication. Since there are two rings bearing flange, so grease the process running in the distribution of special care is needed.

Assuming oil lubrication, must be noted that, compared with the angular contact ball bearings, this product requires a lower volume of oil lubrication. Suppose these two types of bearing assembly with a tie, you must remain independent of the circuit, to avoid excess angular contact ball bearing lubricant injected, resulting in over-lubrication, resulting in bearing temperature is surging.
