Service Caster 1/2 inch inside diameter by 3/4 inch outside diameter by 1.8906 inch long hardened stainless steel spanner bushing designed for caster wheels with a 1-5/8 inch hub length.
This stainless steel spanner bushing is highly durable and built to resist wear in demanding applications. It helps ensure proper spacing and alignment within the wheel assembly. When installed, the bracket, washer, or nut tightens against the spanner, not the wheel, allowing the wheel to spin freely. For best performance, the spanner should be slightly wider than the wheel hub.
