BTU Ball transfer units - CSB® Plastic Bearing Technology

Product properties

In comparison to steel units, ball transfer units out of plastics are non-conductive, resistant to acid and lye, no lubrication, maintenance-free low friction, low weight (up to 70 % less), appropriate for vacuum or pressure, saltwater-proof, free of metallic components depending on selection of materials, transport of fragile goods such as glass, available use in explosive atmosphere and aseptic areas (e. g. medical technology), customized design possible.

CSB-PRB® Plastic Ball Bearings Finder V2.0

view tools

▊CSB-PRB® Plastic Ball 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-PRB® Plastic Ball 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.
