Round Laminated Bearing Pad – Standard and Sliding Type

Round laminated bearing pad is one of the most important shape laminated bearing pad. Standard round laminated bearing pad is made of chloroprene rubber (CR) or natural rubber (NR). The chloroprene rubber laminated bearing bed is suitable for -25 °C to 60 °C. The natural rubber laminated bearing pad, which is also called cold resistant bearing pad can be used in -40 °C to 60 °C.

Structure of round laminated bearing pad

Round laminated bearing pad has similar structure with rectangular laminated bearing pad. It is made of NR or CR rubbers with several steel plate inserted. The rubber and steel plate are inserted, glued and vulcanized together for stable and even bearing load and tensile strength. Except that, we can supply the round elastomeric bearing pad, which is made of all rubber without reinforced plate.

In some applications, which need sliding for shock reduction. We can supply the sliding round laminated bearing pad for you. Sliding round laminated bearing pad, also called PTFE round laminated bearing pad, it is composed of rubbers, steel plates and PTFE board. 2 mm to 3 mm PTFE board are added onto the round laminated bearing pad to form the PTFE bearing pad.
