Precision Brand 25137 Round Arbor Shim Steel Pack of 10

Product Description

The PRECISION BRAND 25137 is a round arbor shim used to fill gaps, adjust clearances, and take up slack in rotating assemblies and mechanical fits. At 0.062 inches thick with a 0.5-inch inside diameter and 0.75-inch outside diameter, this shim is sized for precision fitment around arbors, shafts, and fasteners where tight tolerances matter. Constructed from steel, it provides the rigidity and durability required in industrial, HVAC, and mechanical service applications. Each package contains 10 shims, making it suitable for multi-point installations or repeat service calls. Machinists, millwrights, and mechanical service technicians are the primary installers.

This arbor shim is suited for use in light industrial equipment, mechanical assemblies, and rotating machinery where controlled spacing and alignment are required. Typical applications include shaft and arbor alignment, bearing seat adjustment, and clearance control in pumps, motors, fans, and similar equipment. The steel construction makes it appropriate for both indoor and outdoor mechanical assemblies subject to moderate loads and vibration.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical service technicians. Ensure the assembly is fully de-energized and any rotating shafts are locked out before placing or removing shims. Use calibrated measuring tools to verify stack height and clearance after installation. Follow applicable equipment manufacturer service procedures and relevant industry codes when performing precision alignment work.
