What Is a PSVD2-16E Saddle Bearing?

The PSVD2-16E Saddle Bearing is an important internal component used in hydraulic piston motors or pumps, commonly found in excavators and other heavy construction equipment. It supports the pistons or piston shoes inside the rotary group.

Function of the Saddle Bearing

The saddle bearing performs the following functions:

• Supports pistons or piston shoes inside the cylinder block

• Ensures smooth sliding motion of pistons during operation

• Absorbs radial and slight angular loads

• Reduces friction and wear between moving parts

Importance

A worn or damaged saddle bearing can cause:

• Excessive wear on pistons or the cylinder block

• Loss of hydraulic efficiency

• Vibration or noise during motor operation

• Reduced motor power and rotational smoothness
