Product Detail

Aluminum-Copper With Solid Lubricant Plugs Casting Copper Flanged Bearings JDB Flanged Bearings is backed with Aluminum-Copper alloy with good capability of mechanics, castings and anti-erosion. JDB Flanged Bearings is backed with Aluminum-Copper alloy with good capability of mechanics, castings and anti-erosion. The surface of JDB Flanged Bearingsis regularly and finely machined with sockets in which particular solid lubricant Plugs is filled. Embedded in the falnge part because there is no lubricant, not axial load. The surface of JDB Flanged Bearingsis regularly and finely machined with sockets in which particular solid lubricant is filled. Diamater 31.5mm-63mm hydraulic cylinder is put on the intermediate shaft using fresh products. JDB Flanged Copper Bearings is widely used conditions with mediate load but higher temperature and condition with mediate running velocity etc. Avoid use in seawater.
