The Colson Casters 8" x 2" Hi-Temp Phenolic Precision Ball Bearing Top-Lock Caster (SKU: D4.08109.335 HT BRK7 SS) is specifically engineered to meet the demanding needs of industrial and commercial environments where mobility, safety, and durability are essential. This caster combines advanced materials, precise engineering, and innovative design to deliver superior performance under heavy loads and in high-temperature conditions.
Featuring a robust 8" x 2" Hi-Temp phenolic wheel, the caster is designed to withstand extreme heat, making it an excellent choice for environments like factories, warehouses, and laboratories that require reliable mobility in high-temperature conditions. The wheel’s heat resistance ensures it will not degrade over time, even in the harshest working environments, while providing smooth and efficient rolling.
The caster is also equipped with precision ball bearings, which enhance its performance by reducing friction. This results in smoother, quieter, and more efficient movement, which is critical when using equipment for extended periods. Whether used in factory machinery or medical equipment, the ball bearings reduce the strain on both the caster and the user, ensuring longer-lasting durability and reliability.
Safety and security are also prioritized with the integrated top-lock mechanism. This feature locks the caster in place, preventing unintended movement and providing a stable base for machinery and equipment. Whether you're moving heavy machinery or securing equipment in place, this locking feature ensures that your devices stay where you need them.
Constructed from corrosion-resistant stainless steel, the caster is built to endure tough environments. The material ensures the caster will not rust or degrade even when exposed to moisture or chemicals, making it ideal for use in facilities that deal with wet or corrosive environments.
This caster’s 4" x 4.5" plate size makes it compatible with a wide range of industrial equipment, allowing easy installation without the need for custom mounts. Its ability to support heavy loads while maintaining smooth rolling performance makes it a highly versatile and reliable choice for various applications.
Whether you need casters for manufacturing, assembly lines, warehouses, or other industrial settings, the Colson Casters 8" x 2" Hi-Temp Phenolic Precision Ball Bearing Top-Lock Caster provides the high-performance mobility and durability you need to keep your operations running smoothly and efficiently.

This Colson D4.08109.335 HT Stainless 8" x 2" Hi-Temp Caster with Brake is rated to 1200 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 High Temp Phenolic wheel with a 2" tread width. Phenolic carries high loads on smooth, hard floors and tolerates heat, but transmits more shock than an elastomer tread.
This caster uses a top-plate mount with a 4" x 4-1/2" plate and a 2-5/8" x 3-5/8" slotted to 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 Up to 475°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 High Temp Phenolic 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 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).
Application guidance for load margin, wheel materials, and swivel construction. Confirm ratings against your duty cycle, floor, and temperature before final spec.
Treat published load capacity as a continuous working limit, not a one-time peak. Divide total loaded cart weight (product + rack + fixtures) by the number of casters that share the load, then size so that working load per caster stays at or below about 75% of the rated capacity (a common ~25% margin). On four-wheel oven racks, uneven floors and thermal growth can shift load to two or three casters; if your process routinely parks on imperfect floors, engineer for three-caster support rather than perfect four-way share. Confirm ratings at your process temperature — heat softens many wheel compounds and can lower usable capacity versus room-temperature catalog numbers.
Bypass standard polyurethane when continuous or cyclic wheel temperatures exceed the urethane compound’s published service range (often well below typical bake / washdown-after-heat zones). Spec glass-filled nylon or phenolic (or other high-temp tread systems on the PDP) when racks enter ovens, proofers, or wash tunnels where tread softening, bond failure, or flat spots would appear with PU. Match the wheel to the hottest surface the tread sees, including residual heat after exit, and verify chemical exposure (cleaners, fats, steam) against the material notes on this product. When in doubt, ask for the temperature and duty cycle — we will confirm whether this SKU or a high-temp alternate is the right call.
A traditional kingpin clamps the swivel assembly through a single axial fastener. Repeated side thrust from towing, tugger lines, or AGV path corrections loads that pin and the raceway faces in ways ordinary cart steering does not. Over time that shows up as elongated kingpin holes, brinelled races, or loose swivels. Kingpinless (or forged integrated) raceways distribute thrust through a continuous race path instead of relying on that central pin — better suited when side loads are planned into the duty cycle. Oven-rack and high-temp lines still need the correct wheel material first; upgrade the swivel construction when towing or powered side loads are part of the application, not only when heat is.
