Slewing Ring Bearings

Slewing ring bearings are excellent at handling radial AND axial forces. Mine come in three sizes (L, M and S). Each size has a tool that allows you to easily tighten the two inner rings. The L tool works for M as well. S has its own tool. After assembling the bearing, tighten the two inner rings to your liking and push the lock pin through the hole in the male inner ring.
