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.

This Hudson Bearing NSMBT 5/8 CS 5/8" Nylon Ball Transfer Unit – 125 lb is rated to 125 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.
This caster runs a Nylon wheel. Nylon resists chemicals and moisture and carries high loads, which suits washdown and wet environments.
This caster uses a Stud-Mount mount (1/4"-20 stem). Stem casters press or thread into a socket - verify the stem diameter and length match your existing setup before ordering.
The Nylon wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 13/16" (20.5 mm). Account for it when checking equipment clearance, dock height, and ergonomic working height.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
