DESIGN INNOVATION is a LM-Tarbell Hallmark

Since 1938, LM-Tabell has been involved in many
ground breaking plain bearing applications. In the late
1970's, we were asked to design a special bearing
which would be employed in GE's new F404 engine -
powering a new fighter, the F18. Traditionally, Vespel®
SP series bearings were used in the compressor
vane/shroud assembly. However, on the F404, one
stage of the compressor reached temps which
exceeded the range of Vespel®. Another reason
Vespel® was popular was its lightweight.

Tarbell engineers decided on a CABOT® powdered
metal additive called Triboloy®. We alloyed 15%
of Triboloy® with a host stainless steel powdered
metal. We then took the pm part and machined it.
Machining was critical because the part work hardened
as it was machined - one mistake and it was scrap.

There was loud dissent by GE and the Navy because
of the bearing's weight. However, it worked and it is
still a mainstay on the F404. The bearing can see
temps of over 1000ºF and after 600ºF it creates its
own self lubricating oxides. We have alloyed sintered
bronze with Triboloy® and made SUPER BUSHINGS!
