Description
Description

A Bearing Liner is to support the rotational movement of the swashplate. As the pump's drive shaft rotates, it transfers motion to the swashplate, which in turn adjusts the angle of the pump's pistons. The bearing liner is engineered to ensure proper fit and alignment within the pump housing.

Attributes:
• Withstand the high pressures and forces encountered in the main hydraulic pump
• Manufactured to precise specifications and are built for durability, and reliability

Applications:
A Bearing Liner is used to provide a low-friction surface for the swashplate to rotate against, minimizing energy loss and improving overall pump efficiency.

Warning:This product can expose you to chemicals including Arsenic, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
