Turn an application into a clean, complete caster specification you can print, save, or paste into a quote request. Enter what you know, leave the rest, and the builder fills in the minimum capacity per caster and flags anything missing before it reaches a supplier.
A complete caster RFQ needs six things: total load and number of casters, mount type and plate or stem size, wheel material and diameter, swivel-versus-rigid layout, brake requirement, and environment (temperature, washdown, floor). This builder captures all six and computes the minimum capacity per caster using the N-1 method with a safety factor, so the spec you send is one a supplier can quote without a follow-up email.
Everything updates the spec sheet below as you go.
Tip: copy the spec, then paste it into the quote form or an email to your CasterHQ rep. Nothing is sent automatically.
Floors are never perfectly flat, so on a 4-caster unit you should assume the load can rest on 3 casters at any moment. The builder divides total load by the number of casters minus one, then multiplies by your safety factor:
Capacity per caster = (Total load ÷ (caster count − 1)) × safety factor
Specify casters rated at or above that number. For powered, towed, or high-speed applications, step the safety factor up. This is a planning figure; confirm against the rated dynamic capacity of the specific caster.
