This is the replacement for three arm bearing mounts.  Multiple-holed arms are for universal fit and may need on-site modification to fit your replacement needs.

If you reuse the mountings, you will save money.

TB6769 Ball Bearing
The TA socket has a bronze sleeve bearing.  If you are ordering this we need to know the shaft size.
The TB socket uses a ball bearing. Triangle does not sell ball bearings -- only sleeve bearings.
Often you do net need to replace the Tri-arm mounting or rubber cushion.  If you can remove and replace the bearing only, it will save you money.
