• Sleeve bearings in moderate service can operate on 50% or less of the oil feed required for a full hydrodynamic oil film. • Lower oil-feed rates mean engineers can simplify oil-delivery systems. • ...

Greases help sleeve bearings operate with less maintenance. Understanding bearing oscillation angle, temperature, friction, and grease replenishment requirements will keep bearings working longer.

There are many differences between diesel and gas engines, including some less obvious aspects of engine construction, such as cylinder sleeves.
