Strengthening Brass With Solid Lubricant Casting Bronze Bearings with Flange
JDB Bearing is backed with strengthening brass that has good physical performance and good capability for casting.
JDB Bearing is widely used on consecutive casting and rolling machines, mine-exploiting equipment, ships, steam engine, etc.
Avoid use in seawater.
Strengthening Brass + Solid Lubricant Bearings with Flange can be used with rotary, reciprocating shaking motion and movement.
Embedded in the falnge part because there is no lubricant, not axial load.
What’s more, the brass backing has pretty good anti-erosion ability in air, fresh water and seawater. The surface 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.
