Steel Spanner Bushings:

If wheels with ball or straight roller bearings are mounted in casters they should be equipped with a spanner bushing. If wheels with straight roller bearings are to rotate directly on a shaft (without a spanner bushing), then the shaft should be hardened and ground. For sizes other than shown, please contact us.

You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation
