Product Features
? Engineering plastic wear resistance washer. Suitable for a fitting to the uncontrollable axial space in order to reduce the vabriation and noise during the operation.
Compensate the axial clearance and machining tolerance;
Shock absorbing and noise optimization;
Maintenance free and self-lubricated;
Corrosion resistance and light weight.
Structure Design
CSB-PEW plastic flat spring is designed with a bump axial surface for the purpose of compensates the axial fitting and machining tolerance in addition to function as a normal washer. Therefore the operation mechanism could be more stable and with less noise.
Material Design
CSB-PEW plastic flat spring is made from the professional wear resistance material CSB-EPB13 which provides good wear resistance and excellent spring feature. At the same time, CSB could also provide the spring washer with high temperature (up to 250?) material CSB-EPB5 and FDA approved material CSB-EPB5A.
Assembly Design
In order to adjust the fitting clearance, a single flat spring is usually inserted. For bigger clearance adjustment, a group of flat springs combined with back to back or face to face is also a good solution. If a higher elastic characteristic is needed, piling the flat springs parallel and assembles into the required position.
