Bearing installation

Housing: The bearing housing and the fitting tools must be kept clean during the assembling. A chamfer of 25。on the housing should be ensured for an easy assembling. A stepped press pin is recommended to be used for the assembling. The inner diameter of the CSB-EPB® plastic bearings is measured after the bushing is fitted into the H7 housing. CSB-EPB®塑料轴承安装方法

Shaft: There is no critical requirement for the shaft material but chrome plated shaft is recommended for better operation. Rounded chamfer is required on the shaft for easy assembling. CSB recommend the shaft roughness to be in the range of Ra0.2~Ra0.8. Please refer to Graph 15 for the relation between the surface roughness and bearing friction coefficient (Graph:19). 

CSB-EPB® plastic bearings are designed according to ISO 3547 Standard (Graph 18). Although the CSB-EPB® plastic bearings are designed for self-lubricating purpose, but the initial lubricating helps the assembling and the future operation of the bearings. 

Adhesive agent: CSB-EPB® plastic bearings assembly generally needn't use glue, in case the glue is necessary, please consider the used glue can also work properly at the required temperature. Relative testing is recommended in this case. 

CSB-EPB® Plastic Bearings Finder[V2.0] is based on the analysis and calculation of a large number of test data in CSB® laboratory. You can calculations material data by entering parameters such as bearing load, speed, and temperature, and finally output material adaptation data.
Because the system calculate and analyze based on lab data, it can't exactly meet the ractual use requirements absolutly. The system data verification has certain limitations; CSB® recommends that the bearing must be tested again to verify whether it meets the actual use requirements.
CSB-EPB® Plastic Bearings Finder output data information is only for design reference, and can not be used as the final standard for determining the bearing material conformity, If you have any questions, please contact CSB® sales engineers.

CSB® bearing material chemical resistance data is a comparison test result of the CSB chemistry laboratory using laboratory specimens or similar chemicals at room temperature 23 ℃, without considering the impact of other temperatures and chemical medium mixtures on the chemical resistance of CSB® bearing materials ; Therefore, this data can only act as a reference. CSB® recommends that the chemical resistance of actual parts should be tested under application conditions and verify the suitability of the bearings.
