6" x 3" Phenolic Casters | 2,000-2,500 lb

The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Choosing 6 x 3 in phenolic casters

Load: divide the loaded weight by three for a four-caster cart [S2]. A 2,500 lb caster from this page then suits about 7,500 lb, and the strongest at 2,500 lb about 7,500 lb.

Mount: most 6 x 3 in phenolic casters use a 4-1/2 x 6-1/4 in top plate; check the bolt spacing on your frame against the plate size.

Floor: on 6 x 3 in phenolic casters, phenolic suits smooth concrete and heavy loads, but is loud and hard on tile and wood.

Rig: rigid and swivel 6 x 3 in phenolic casters are listed.
