Features

Hardened and ground spanner bushings are a standard bearing component of the caster wheel.  A simple solution to reduce the bearing's inner diameter to the proper axle outer diameter that your caster yoke (fork) requires.  Most common applicable bearings include roller bearingsprecision sealed ball bearings, delrin bearings, or plain bore wheels (no bearing). Four basic varieties of spanner bushings are available:

  • Delrin Spanner Bushings are a single-piece component, that spans the width of the wheel hub.  Very economic, durable and strong, improves rollability  Often used with plain bore wheels.  Resists water, moisture, most chemicals, solvents, and grease.  Do not exceed temperatures of +250° F.
  • Delrin Top Hat Spanner Bushings is a dual-piece component, inserted on both sides of the wheel hub.  Most often used with Precision Sealed Ball Bearings.  Resists water, moisture, most chemicals, solvents, and grease.  Do not exceed temperatures of +250° F.
  • Steel Spanner Bushings are a single-piece component, that spans the width of the wheel hub.  Steel is more popular than delrin, and preferred for use with Roller Bearings.  Compatible with high temperature applications, and high friction usage.  (Option: 304 Stainless Steel spanner bushings.)
