Kinney Sleeve Bearing – 2 1/8, Part# 054109

This is the Kinney Sleeve Bearing – 2 1/8″, Part# 054109. Unlike ball bearings that roll, this is a sleeve bearing. It works with a sliding action. One part spins or slides inside the other. It is simple but very strong.

Sleeve bearings are built for heavy work. They have a few special traits:

• High load capacity – They can take a lot of weight without breaking .

• Low wear – They last a very long time, even with constant use .

• Handles shaking – They work well with high frequency oscillating movements (that is a fancy way of saying parts that shake or vibrate fast) .

• Less friction – The sliding action creates a smooth film of oil. This keeps heat down .
