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.
