Products Description
Serving as a rugged radial wear sleeve capable of absorbing harsh rotational impacts, our Bimetallic Hydraulic Motor Bushing lines a low-carbon steel sleeve with a CuPb10Sn10 bronze alloy bearing face. We supply this press-fit Bimetallic Hydraulic Motor Bushing for drive shafts and output journal assemblies across industrial hydraulic motors, farm implements, and conveyor equipment. Manufactured to an ISO H7 internal tolerance, our Bimetallic Hydraulic Motor Bushing eliminates secondary line reaming upon installation, while integrated internal oil pockets provide continuous boundary lubrication during frequent motor starts and stops.
Application Scenarios
- Output drive shaft support and internal journal guiding in hydraulic motors.
- Auxiliary hydraulic drives in agricultural harvesters, seeders, and material conveyors.
- Fast-turnaround motor rebuilds and aftermarket overhaul kits.

FAQ
Q: Can this bushing be installed directly without post-assembly boring?
A: Yes. When pressed into a standard housing bore, the precision H7 inner diameter provides proper running clearance immediately without secondary machining.
Q: How are small-to-medium bushing orders packaged for export?
A: Small batches are packed in moisture-sealed bags inside reinforced wooden crates secured with iron locks to prevent impact damage.
