 | Ultra-Performance Acetal (POM) | Ultra-performance special acetal resin is particularly suitable for applications where low coefficient of friction and contained dusting are needed. |
 | Special Kevlar Reinforced Acetal (DK2) | A next generation material, Acetal resin reinforced with kevlar was developed by REGINA. This material is able to reach the lowest coefficient of friction with maximum wear resistance. Thanks to the superior material qualities, the usage of lubricants can be drastically reduced or eliminated without losing performance in conveyor applications. |
 | Austenitic Stainless Steel (Pin Material) | Cr-Ni austenitic cold rolled stainless steel. It guarantees the best corrosion resistance to withstand chemical attack. It offers very good wear resistance, due to work hardening and homogeneous chemical structure. |
