Steel Back Aluminum Bushing (Lead Free)

The A66T alloy bushing was added to the F-series bearing line-up as a compliment to the polymer plain bearings. The A66T material is a lead-free bearing containing a superior aluminum alloy composition including tin, silicon and copper. This material composition provides many customers with a new alternative machinable bearing material to replace outdated bearings. The A66T bushings are commonly produced to custom OE design making them a made to order item.

Aluminum Alloy bushings are designed to run in a fully lubricated environment usually with pressurized oil. The alloy layer allows for machining for tight tolerance oil clearances after installation into a housing bore. The ID can contain embossed oil groove designs for improved lubrication. A66T bushings are ideal in small or large engines, compressors and various types of pumps.

Features
A66T bushings start with a steel backing for high mechanical strength, dimensional rigidity, and heat dissipation (A). Next comes a rolled clad bonding key to bearing wear resistance (B). Finally, there is a high quality aluminum alloy layer thick enough for ID machining and maintaining oil grooves or indents for oil retention (C). The alloy layer provides the anti-friction properties.


A.) Steel backing
1010 mild carbon steel. The thickness of the steel varies according to the size of the bearing.

B.) Bonding Layer
A robust roll clad bonding technique is used to bond the cast aluminum and steel creating a bi-metal bearing.

C.) Aluminum Alloy Layer
A low friction aluminum alloy composition designed for maximum wear and seizure resistance. The alloy layer varies depending on the total wall thickness.
