Raymond Shim RA850-402 – HW-2072

Setting a precise clearance or alignment is what this Raymond shim does, a thin, flat spacer slipped into an assembly on Raymond equipment to take up gap, set preload, or square one part against another. Technicians add or remove shim material to dial in the small dimensional adjustments that bearings, mounts, and mating surfaces need to sit and run correctly.

At roughly 1 by 4 by 1.5 inches and about 0.1 pounds, it is a light, precise piece whose exact thickness is the whole point: too little and a joint runs loose, too much and it binds. Match the shim's thickness and its footprint to the original in the stack being serviced, since the thickness is what determines the clearance it sets and a shim of the wrong size changes the fit of everything around it.
