Aluminum-Bronze With Solid Lubricant Casting Bronze Flanged Bearings
JDB Flanged Bearings is backed with Aluminum-Bronze alloy with good capability of mechanics, castings and anti-erosion. The surface of JDB Flanged Bearings is regularly and finely machined with sockets in which particular solid lubricant is filled.
Embedded in the falnge part because there is no lubricant, not axial load.
The surface of JDB Flanged Bearings is 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 Bronze Bearings is widely used conditions with mediate load but higher temperature and condition with mediate running velocity etc.
Avoid use in seawater.
