1. The thing mingles with PTFE, oleophilic fiber could form the good transform membrane to protect the rubbing each other bearing.
2. Good hard wearing, low friction value
3. Good break in, no block appearance.
4. Could use in the active of revolve around, swing and reciprocate
5. No lead content so that it could use in the food machinery, medical machinery and other green environmental protection equipment.
6. Beside content the advantages of RCB-1P, it is suit for the place of reciprocates frequently and big side force. It is suit for the dashpot and hydrocylinder in vehicle and motorbike.
