With over 35 years of experience in caster manufacturing, Durastar has established itself as a trusted name in the industry. The 04 Series casters are designed with precision and manufactured to meet the highest standards of durability and performance. By choosing Durastar, you're investing in a product that combines innovation, reliability, and exceptional value.
Swivel casters play a crucial role in improving industrial efficiency. Their ability to rotate 360 degrees enables smooth movement of loading equipment, enhancing durability and performance. In industrial settings, these heavy-duty swivel casters are commonly used to move heavy machinery or equipment from one place to another with minimal effort, significantly improving workplace productivity and ergonomics.
This 3" x 1-13/16" Sirius HD Polyurethane Swivel Caster – 550 lb is rated to 550 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 Polyurethane wheel with a 1-13/16" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.
This caster uses a top-plate mount. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.
This is a Swivel caster. Swivel casters rotate 360 degrees for full maneuverability. 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 Polyurethane wheel performs best on smooth to semi-smooth floors including sealed concrete, tile, and epoxy. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 4-1/4". 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).
