Products Description
Engineered to deliver high radial support without risk of bearing seizure, our Bimetallic Hydraulic Pump Sleeve Bushing lines a low-carbon steel casing with a CuPb10Sn10 bronze alloy bearing face. We manufacture this Bimetallic Hydraulic Pump Sleeve Bushing for drive shafts and idler journal supports in industrial hydraulic pumps, agricultural tractors, and mobile lift units. With internal diameter tolerances held to H7 standards, our Bimetallic Hydraulic Pump Sleeve Bushing installs directly via press-fit without line-boring, providing built-in oil reservoirs that sustain hydrodynamic lubrication under heavy loads.
Application Scenarios
- Drive shaft and idler gear journal support in industrial and mobile hydraulic pumps.
- Guide bushings and shaft bearings in agricultural machinery and material handlers.
- Quick-turnaround aftermarket pump cartridge overhaul and field repairs.

FAQ
Q: Does this bushing require reaming or secondary boring after press-fit?
A: When pressed into a nominal housing, the H7 bore tolerance maintains correct operating clearances directly, eliminating secondary machining.
Q: What shipping terms do you accommodate for overseas buyers?
A: While our standard commercial term is EXW Qingzhou, we regularly arrange FOB Qingdao and CIF port delivery upon request.
