HLDB-JDB

Metallic self-lubricating bearings with graphite plug

Suitable for high static and dynimic loads

With low and smoothy coefficient of friction and without stick-slip effects

Suitable for dirty, corrosion, impact load and edge loading

The base material provided a good shock-absorbing capacity

Can be used over a large temperature range

Suitable for reciprocating, rotating and oscillating movement with start frequency and difficulty to form oil film occasions

With low wear rate and long life service

Additional lubrcation oil groove or oilhole, according to demand!

Cylindrical and flanged bushing, thrust washer, wear plant. 

Standard or non-standard, on demand!

We can also develop according to customers special request. Data for sliding bearing design calculation Pls click here

  • 应用领域
  • HLDB-JDB materials(CuZn25Al5Mn4Fe3) consist of highly wear-resistance copper cast alloy whose sliding surfaces are evenly provided with a certain percentage of solid lubricant plugs according to work condition. High-strength copper alloy provides a high load-bearing capacity and the solid lubricant can be formation of low friction film. Under technical dry running conditions, the bearing surface is designed with thick running-in film which enables the solid lubricant to be transferred to the counter material at the first contact.
