RCB-1P Reciprocating Motion bush


China RCB-1P DU composite slide bearing

RCB-1P Oilless bearing is based on the structure of RCB-10 material and it’s design is according to special work condition of reciprocate. It is a new compounding products and its function is similar with DD2 in foreign country.

Advantages of dry bearing

(1) Green environmental protection

There is no need to recycle waste oil, which is conducive to environmental protection.

(2) Reduce the requirement of grinding parts

The hardness of grinding shaft is low, and the grinding shaft without quenching and tempering treatment can be used, which reduces the machining difficulty of related parts.

(3) High and low temperature resistance

It is resistant to high and low temperature. The service temperature of some products is - 200 ℃ to 600 ℃



Besides of owns characteristics of RCB-10, RCB-1B is good at the follows:
Bronze plate owns self-lubricating performance, which can be used in the components that are difficult to add oil, so that the part owns letter anti-corrosive characteristic that HTB-10. The products can be widely applied in chemical environment or port heavy machine, marine machine steel industry etc. Moreover, it can be mated with steel bushing or be made with flange, and the two surfaces are all do works.

We are provide many top quality products, such as composite bearing, steel bronze bushing, precision steel bushing, ejector guide bushing, harden steel bushing, bimetallic bearing, guide posts bushing and so on.
