Substrate characteristics


RCB-650 uses high-strength copper alloys (CuZn25Al5, CuZn24Al6Fe3Mn4, SAE430B, HBsC4) as the basic material. According to the working conditions, holes are machined on its working surface and filled with solid lubricants in a certain proportion. The high-strength copper alloy provides very High load-bearing capacity and solid lubricants can form a lower friction pair. Under dry friction conditions, we design a pre-lubricating film on the bearing surface to ensure that the solid lubricant is transferred to the mating part in the shortest time and an effective solid lubricating film is formed.,






Material characteristics:


·Can be used for a long time without maintenance;
·Designed for high static load and dynamic load;
 ·It has a very low and stable friction coefficient, no "sticky" phenomenon;
·Dust resistance, corrosion resistance, impact resistance and edge load resistance;
 ·Metal base material has good shock absorption ability;
 ·Can be used in a wide temperature range;
·Suitable for occasions where reciprocating, rotating and swinging starts frequently and it is difficult to form an oil film;
·It has extremely low wear rate and long service life.
