Product Overview
The Bimetallic Vane Motor Wear Plate is developed for the oil-distribution requirements of vane motors. Its symmetrical port structure supports motors that frequently switch between forward and reverse rotation.
Composite Material
The product combines a carbon steel base with a CuPb7Sn7Zn3 copper alloy friction layer.
The two materials are formed through an integrated sintering and rolling process.
Structural Support
The carbon steel base provides rigidity and limits deformation under hydraulic pressure.
The copper alloy surface offers self-lubricating performance and helps reduce friction heat during operation.
Symmetrical Port Design
A symmetrical oil-distribution structure is used to match bidirectional vane motor operation.
This design helps reduce reversing impact and supports smooth motor movement when the rotation direction changes.
Low-Speed Performance
The self-lubricating bronze surface supports stable operation at low speed.
It helps reduce creeping, uneven movement, and temperature rise during low-speed motor operation.
Pressure Pulsation Control
The distribution window design keeps pressure pulsation within ±5%.
The standard rated working pressure is up to 21 MPa. A customized high-pressure version can be produced for operation up to 28 MPa.
Wear and Seizure Resistance
The copper alloy layer provides resistance to galling and scoring.
This helps reduce the risk of vane sticking and damage to the oil-distribution surface.
Precision and Replacement
End-face flatness is controlled within 0.004 mm, and surface roughness is Ra 0.2 μm or better.
Consistent dimensions allow the Bimetallic Vane Motor Wear Plate to replace a matching original part directly.
Application Areas
The product is suitable for single, double, and fixed-displacement vane motors.
It can also be used in injection molding machine adjustment motors, machine tool hydraulic rotary tables, and light machinery drive systems.
Order Information
OEM and ODM services are available. The minimum order quantity is 100 pieces, and several models may be combined in one order.
Custom samples require about 30 days. Standard delivery is 25–30 days. The preferred trade term is EXW, with settlement mainly in US dollars.
