All measurements indicate the wheel diameter by the tread width.
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.
Sizing your casters right is the difference between a 6-month replacement and a 5-year service life. These engineer-built calculators apply the same N-1 load method, push-force formulas, and wheel-material logic our application engineers use to spec custom OEM builds — free, no signup.
From quick load math to complete cart layout planning. Each tool returns engineer-validated outputs and links to recommended SKUs.
Load Rating = (Total Cart Weight ÷ 3) × 1.25. Apply N-1 method + dynamic safety factor for industrial applications.
Open Calculator →Estimate ergonomic push force per NIOSH guidelines. Validate operator safety before deploying carts.
Open Calculator →Match wheel diameter to floor condition + obstacle clearance. Larger diameter = smoother roll over thresholds.
Open Calculator →Polyurethane vs rubber vs phenolic vs cast iron — pick the right material for your floor, load, and environment.
Open Selector →Plan 4-caster, 6-caster, or specialty layouts. Position rigid + swivel for tracking, turning, and load distribution.
Open Tool →Filter the full 50,000+ SKU catalog by load, mount, wheel, brake, and material. Returns matched products + spec sheets.
Open Finder →Diagnose why your caster failed (kingpin shear, wheel deformation, bearing seizure, brake slip). Get root-cause analysis + replacement spec.
Diagnose Failure →Download STEP, IGES, DXF, and PDF spec sheets for any SKU. Free for OEM accounts within 24 hours of request.
Request CAD Files →Reference content for engineers, procurement, and MRO buyers. Each guide includes spec tables and engineer tips.
