Precision Brand 26161 Round Shim Spring Steel 50 Pack

Product Description

The PRECISION BRAND 26161 is a round shortening shim made from 1075 spring steel, designed for precise axial spacing and load distribution in mechanical assemblies. At 0.015 inches thick with a thickness tolerance of plus or minus 0.00075 inches, this shim delivers tight dimensional control where stack-up accuracy matters. The 0.501-inch inside diameter and 0.738-inch outside diameter are sized for use with 1/2-inch fasteners or shoulder bolts. Machinists, millwrights, and maintenance technicians install these shims during equipment alignment, bearing retention, and component spacing work across industrial and trade applications.

This shim is suited for mechanical assemblies requiring precise gap adjustment or load transfer at 1/2-inch screw or shoulder bolt locations. The shortening shim profile makes it appropriate for reducing axial play in shaft assemblies, aligning pulleys or sprockets, and correcting tolerance stack-up in equipment repairs. The spring steel construction handles moderate compressive loads without permanent deformation, making it a reliable choice for both OEM builds and field service repairs. Each package contains 50 shims, providing enough quantity for production runs or stocked maintenance inventory.

Key Features

• Shortening shim type for axial spacing and gap adjustment in mechanical assemblies
• 1075 spring steel construction resists permanent deformation under compressive load
• 0.015-inch nominal thickness with a tight tolerance of plus or minus 0.00075 inches
• 0.501-inch inside diameter sized for 1/2-inch screw or shoulder bolt fitment
• 0.738-inch outside diameter for broad load distribution around the fastener
• Packaged in quantities of 50 for production and service inventory use

Compatibility

Designed as an OEM-style replacement or service shim for mechanical assemblies using 1/2-inch fasteners or shoulder bolts where a 0.015-inch thick round shortening shim is specified.

Installation Notes

Installation is typically performed by machinists, millwrights, or equipment maintenance technicians. Always de-energize and lock out equipment before disassembling any assembly that requires shimming. Verify shaft, bore, and fastener dimensions before selecting shim thickness to ensure proper stack-up. Do not exceed the compressive rating of the assembly by stacking shims beyond the design specification.
