Spanner Bushings for Casters and Wheels


Caster Headquarters offers a full industrial line of Spanner Bushings commonly used to reduce the bore size of a wheels bearing down to fit a specific axle or shaft size. Spanners also known as Spanner Bushings are used in almost every caster and wheel in the Caster Industry. Any wheel that comes with a Roller Bearing will always include a spanner bushing which works as a reducer to fit the preferred axle when assembling casters. Spanners can also be used in a wide array of other industrial applications as well. We offer spanner bushings in many sizes from 5/16" ID (Inner Diameter) all the way to 1-1/4" ID (Inner Diameter) that will fit a range of bores from 3/8" OD (Outer Diameter) all the way to 1-1/2" OD (Outer Diameter). If you can't find the size you're looking for please feel free to reach out to us Monday through Friday between 8am and 5pm for one of our Material Handling Experts to help you find exactly what you're looking for.
To make it easier please use the chart below when ordering spanners for casters. All spanners are made to fit with a specific width/hub lengths of caster wheels. If you are needing a spanner to fit a wheel that is 2" wide there is only one spanner that will fit that wheels hub length. Same goes for 1-1/4" Wide Wheels, 2", 2-1/2" and 3" Wide Wheels. Follow the list below if it is caster related. If you plan on using the spanners aside from casters please disregard the list below.
