Ball Bearing – 45 mm, Kinney, Rotary Piston, Part# 54115

This ball bearing is made specifically for Kinney rotary piston pumps. It measures exactly 45 mm in diameter. That is the right size for the pumps listed below.

This part fits two specific Kinney pump models :

• Kinney KT300C

• Kinney KT300D

These are medium to large rotary piston pumps. You will often find them in industrial settings like food packaging lines, vacuum forming machines, and central vacuum systems in factories.

A good quality bearing does three important things:

1. It keeps the shaft spinning straight without any wobble.

2. It reduces friction so the motor does not have to work too hard.

3. It stops metal parts from rubbing directly against each other.

 They make replacement parts that match or exceed original factory specifications.
