TB-092 is a straight wrapped bronze bearing made of tin bronze alloy. The bearings have lubrication holes in the sliding surface. These holes enable a lubrication film that works from the very first movement.
This cold-rolled bronze alloy has excellent properties in applications with high loads and relatively slow movements. This bearing material performs very well in dirty conditions. Additional lubrication is always required.
