Bearing, Sleeve, Kinney, Rotary Piston, KT850C, KT850D, Part# 54108

This is the Kinney Sleeve Bearing – 2 1/2″, Part# 054108. Some people call it a “race” . It is not a ball bearing. It is a sleeve bearing. That means it works with a sliding action instead of rolling. One part slides smoothly inside the other.

This bearing is made for these specific Kinney models:

• Kinney KT850C 

• Kinney KT850D 

These are bigger, powerful pumps. They need heavy-duty parts to stay reliable.

Sleeve bearings have some great qualities for tough jobs like this:

• High load capacity – They can handle a lot of weight without failing.

• Long life – They are built to last a very long time, even with daily use.

• Low friction – A thin film of oil keeps things sliding smooth. This reduces heat and wear.

• Quiet operation – No rolling noise. Just smooth, quiet movement.
