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.

2-1/2″ x 7/8″ Caster Replacements: buying guide

The 2-1/2″ wheel sits between 2″ and 3″ — same 7/8″ tread width as both neighbors, but pulls slightly more capacity (up to 110 lb each on the brake variant) and rolls easier across small floor seams. Used on small AGVs, light service carts, furniture casters that need a touch more clearance, and replacement matches for equipment originally specified at 2.5″ wheel diameter.
