PYB Small thickness  plastic bearings

Product properties

● Thin-walled plastic bearing for quick installation. It is made with CSB-EPB3M material wich is flexible for dimension viriation. Alternative material CSB-EPB7 is also available for special wear resistance requirement.
● Maintenance free, self-lubricated.
● Side groove designation for easy assembly.
● Groove design reserves the material expansion allowance.
● Suitable for rotation and sliding motions.

PYB Small thickness plastic bearings, Metric

Structure design

CSB-PYB® thin wall plastic bearing is designed with thinner wall comparing with the standard plastic bearing for those applications with small assembly spaces. Slipped gap ensures easy assembly of the bearings. 

Material design

CSB-PYB® is also made from CSB-EPB3M material which is a good wear resistance polymer. The bearing self-lubricating performance is excellent for dry operation conditions. At the same time, continuous lubricating is allowed during the operation because this material is also with good isolation feature against the most common lubricants.

Assembly design

The spiral shape slip gap could not only make the bearing easy to be pressed into the metal housing, but also help to compensate any possible material expansion caused by the squeeze derived from the pressing. The recommended housing tolerance is H7 while the bearing could fit with the housing tolerance range up to H13. The bearing is allowed to be rotating in the housing after assembling.

CSB® Bearing Material Chemical Resistance

Please select bearing material and medium...

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.
