Industrial 8" flat-free caster built for outdoor terrain and maintenance environments. Delivers pneumatic-style cushioning without air loss, punctures, or downtime.
Flat-free polyurethane tires provide shock absorption similar to pneumatic wheels but are firmer under heavy static load. For constant high-load industrial use, consider stepping up to a higher-capacity configuration.
Foam-filled construction delivers pneumatic-style shock absorption without air loss, punctures, or downtime. Ideal for outdoor environments where debris and sharp objects are common.
Supports up to 275 lbs per wheel under evenly distributed static load conditions. Suitable for mobile equipment, carts, generators, and maintenance platforms.
Broad tread face improves load distribution and traction across grass, gravel, dirt, and uneven terrain while reducing floor marking on finished surfaces.
Maintenance-free ball bearings provide smooth rotation and reduced rolling resistance for improved maneuverability under load.
Full 360° swivel rotation with stable mounting footprint. Designed for predictable steering and controlled movement of mobile equipment.

This 8" x 3" Foam-Filled Polyurethane Swivel Flat-Free Caster – 275 lb is rated to 275 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 3" 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 9-3/4". 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).
