Caster HQ's Polyurethane elastomer tread chemically bonded to cast iron
core offers high weight capacities while providing good floor
protection and a quiet rolling operation. Optional precision ball bearings require less effort to start up and maintain a rolling load; they
also generate less friction heat and may prolong the life of
the wheel. This Caster and Wheel Work well in indoor and outdoor environments; however, the cast iron core can rust with lots of exposure to wet environments; if this is an issue, consider using aluminum or plastic core wheels.

This 4" x 2" Polyurethane Rigid Caster – 800 lb is rated to 700 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 Cast Iron wheel with a 2" tread width. Steel / iron wheels give maximum capacity and durability on smooth, hard industrial floors and tolerate heat.
This is a Rigid caster. Rigid casters track straight for directional stability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -20°F to 180°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Cast Iron wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.
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).
