Precision Brand 25115 Round Arbor Shim 0.031in Steel 10-pack

Product Description

The PRECISION BRAND 25115 is a round arbor shim made from steel, designed to fill gaps, adjust tolerances, and set precise spacing in mechanical assemblies. At 0.031 inches thick with an inside diameter of 0.375 inches and an outside diameter of 0.625 inches, this shim fits arbor-style applications where tight dimensional control is required. Sold in a package of 10, it suits maintenance shops, machine shops, and field service operations that need consistent stocking of small-format shims. Machinists, millwrights, and mechanical contractors are the primary installers.

Arbor shims at this size range are commonly used in light industrial and mechanical maintenance applications. Typical scenarios include spacing saw blades, grinding wheels, and other rotary tooling on arbors; adjusting shaft end play; and correcting minor misalignment in equipment housings. The 0.375-inch ID fits common small-shaft and arbor diameters, making this shim useful across a range of precision alignment tasks in both shop and field settings.

Key Features

• Steel construction for durability and dimensional stability under load
• 0.031-inch thickness for fine tolerance adjustment in arbor and shaft assemblies
• 0.375-inch inside diameter fits standard small arbors and shafts
• 0.625-inch outside diameter provides adequate bearing surface without interference
• Pack of 10 supports stocking for recurring maintenance needs
• Arbor shim type suited for rotary tooling and shaft spacing applications

Compatibility

Designed as an OEM-style replacement and general-use arbor shim for mechanical assemblies requiring a 0.375-inch ID and 0.625-inch OD round shim at 0.031-inch thickness.

Installation Notes

Arbor shims are typically installed by machinists or millwrights as part of tooling setup or equipment alignment procedures. Before installing or removing shims, de-energize and lock out the equipment in accordance with applicable OSHA lockout/tagout procedures. Verify shim thickness with a micrometer before installation to confirm dimensional accuracy. Do not substitute shims of differing thickness or material without confirming that the assembly tolerances allow for the change.
