Tests were conducted
to compare the load carrying capability and wear life of four standard
self-lubricating bearing products. Transport Dynamics performed all
testing on the same test machine and fixturing. Standard FIBERGLIDE®
and FABROID® products are presented herein. Transport Dynamics offers
other self-lubricating bearing products capable of dynamic loading to
40,000 psi and ultimate static loading to 120,000 psi.
The bearings were
placed under a fixed load with an oscillating shaft. The test bearing
size was 1.00 inch I.D. by .500 inches long. The test conditions were
10,000 psi (5,000 lbs.) and 5,000 psi (2,500 lbs.) loads with an oscillation
of +/- 45 degrees and 30 cycles peer minute at room temperature. Approximately
every 10,000 cycles, the bearings were removed and inspected for wear.
