Spanner Bushing/Spacer Bushing/Adapter Sleeve - (1/2" x 3/4" x 2-7/16") SPANNEREX2

A spanner bushing, also known as a spacer or adapter sleeve, plays a critical role in the world of casters and wheels. Reduces Bore Size: Wheels often come with a larger center bore diameter than the axle they need to fit on. Spanner bushings act as adapters, reducing the wheel’s bore size to create a snug fit on the axle. This ensures the wheel stays securely centered and minimizes wobble during operation. In some applications, wheels might require specific spacing to maintain proper alignment. Spanner bushings of specific lengths can be used as spacers to achieve the desired axle separation between wheels. This spanner fits any 2-inch-wide wheel with a ¾” roller bearing.
