Block, Bearing Support (unreamed) - carton of 10 ea
WIP stands for "Work in Progress" - that is because these parts ship without final reaming. Per drawing, the central through-hole should be reamed to target 1.250-1.251in. and customer is responsible for this operation.
Important note: We manufacture certain specific replacement components for Bridgeport Milling Machines. We are molders, not service technicians. If you need small quantities or technical expertise, we can direct you to resellers who are experts for those very real needs.
