Mining seals usually are multi-part seals with additional back-up rings and pre-loading elements in order to meet the increased requirements of a particular application.

Mining seals resemble the usual piston and rod seals, but have been adapted to meet the demands of high hydraulic pressure of mining applications.

The majority of our mining seals are manufactured in PU, but we also produce them in NBR and POM.

*For technical reasons POM should be used up to a maximum temperature of 80°C only. For higher temperature we recommend Aluminium/Steel. **The maximum pressure allowance for dynamic and static application is dependent on the profile design.
