12mm ID Steel Spacer (15mm OD, 43mm Length) - 4 Pack

These 43mm long steel spacers are designed to set a precise and reliable axial distance between components in a mechanical assembly. They are ideal for use with 12mm diameter shafting, including 12mm REX® shafting, and are commonly used to separate a hub or drive component from a bearing. They feature a durable zinc-plated finish for enhanced corrosion resistance and come in a convenient 4-pack.

Importantly, this spacer’s 43mm length matches the inside width of goBILDA® 1120 Series U-Channel, which is the core structural component of the goBILDA® build system. To that end, this spacer’s 43mm width matches that of many other goBILDA® structural components, like a number of the 1201 Series Quad Block Mounts!
