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.
Plate dimensions shown are overall mounting plate size. When replacing existing casters, select the closest plate size and verify bolt-hole compatibility. BHP = Bolt Hole Pattern, shown under each plate.
High-capacity casters for industrial carts, fixtures, and equipment where you need load strength with better floor protection and quieter rolling than all-metal wheels.
Best for
OEM builds, MRO replacement, production carts
Why engineers specify
Iron core strength + polyurethane tread compliance
Typical sizes
4"–8" wheels (varies by series)
Capacity class
Up to ~1,250 lb/caster (configuration dependent)
Spec notes for purchasers & engineers
85A vs 95A durometer: softer = more shock/obstacle compliance; harder = lower rolling resistance
Floor fit: performs best on concrete and industrial surfaces; tread reduces noise vs steel
Selection rule: base capacity on the lowest-rated component (wheel, rig, bearing, brake)
