Bearings on Our Machines

The following chart shows the bearings on LittleMachineShop.com lathes, their drawing numbers, links to parts, and industry nomenclature for NSK, SFK and FAG manufacturers. The final column gives the key dimensional data for the bearing.

NOTE: LittleMachineShop.com has instructed the factory to use bearings by NSK (or equalivent quality) on all of our machines. We stock similar quality bearings in our replacment part inventory.
