About these bearings
ZKLN bearings are double-direction axial angular contact ball bearings for ball screw supports. ZARF bearings are axial needle or cylindrical roller bearings with a flanged outer ring, used where very high axial stiffness is needed in a small space.
Sizes are written into the number — for example the bore and outside diameter follow the ZKLN or ZARF letters. Send us the full number from your machine and we will confirm the sealing, preload and brand before quoting.
