The 8" x 2" Stainless Polyolefin Roller Bearing Side-Lock Caster with a 4" x 4.5" plate (model D4.08109.839 BRK7 SS WB29) is a high-performance caster designed to meet the demands of industrial and commercial applications. This durable caster offers a blend of advanced materials and engineering to ensure smooth operation and long-lasting performance even in the most challenging environments.
Manufactured with stainless steel, this caster is built to resist corrosion, making it ideal for use in wet or high-moisture environments. The FDA-approved food-grade grease ensures smooth and reliable performance in temperatures ranging from -40°F to 600°F, which is essential for handling extreme conditions, including exposure to food-safe environments.
One of the standout features is its full double ball hardened raceways, which increase the caster's durability and reduce wear, ensuring a long service life. Combined with the precision roller bearings, this caster delivers smooth, quiet operation and the reliability required for demanding industrial tasks.
The caster's 900 lbs load capacity ensures that it can handle heavy-duty applications without compromising performance. With a swivel radius of 6.5 inches, the caster offers outstanding maneuverability, allowing users to easily navigate tight spaces. This makes it an excellent choice for environments where precise movement is essential.
For added stability, the caster is equipped with a top lock brake (model DTBRK7) to keep it securely in place when stationary. Whether you’re moving heavy machinery or ensuring safety in a busy warehouse, the side-lock mechanism provides peace of mind by preventing unintended rolling.
With a 4" x 4-1/2" top plate and a bolt hole pattern of 2-5/8" to 3" x 3" to 3-5/8", this caster is designed for quick and easy installation in a variety of setups. The caster is also low-maintenance, with no thread guards, making it easier to keep clean and service.
Each caster undergoes rigorous testing to ensure it meets the highest standards of performance. The product is RoHS compliant and an NSF component (excluding thread guards), confirming that it adheres to strict environmental and health regulations. With a 3-year warranty, customers can rely on this caster for long-term use without worrying about premature failure or quality issues.
This Colson D4.08109.839 8" x 2" Polyolefin Stainless Side Lock Caster is rated to 900 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 Polyolefin wheel with a 2" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.
This caster uses a top-plate mount with a 4" x 4-1/2" plate and a 3" x 3" bolt pattern. 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 with Brake caster with a wheel brake. Swivel casters rotate 360 degrees for full maneuverability. The brake locks the wheel to hold the load in place. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -40°F to 600°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 Polyolefin 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 9-1/2". 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).
