Industrial 25193 7 8x1-3 8x.020 Arbor Shims

Precision arbor shims part 25193 come in a ten-pack of low-carbon steel spacers designed for reliable arbor alignment, machined to dimensions 7/8 x 1-3/8 x.020 in, making them suitable for fine spacing adjustments on common machine tool arbors. They are intended for use in milling and turning applications to set proper spacing between components such as chucks, arbors, and adapters, and can be stacked with other shims to achieve precise clearance in rotating assemblies across a variety of machine tool configurations. Made from low-carbon steel, these ten pieces provide durable, dimensionally stable spacers for repeated use in workshop environments, supporting consistent setup across multiple jobs and enabling quick, repeatable alignment when assembling tools and fixtures that ride on an arbor. The package contains 10 pieces, providing a ready supply for routine machine setup, experimental shim stacks, or contingency spares, so shops can maintain alignment without delaying projects when a shim is needed.
