The 4" x 2" Stainless Hi-Temp Phenolic Delrin Bearing Side-Lock Caster (Model: D4.04109.331 HT BRK7 SS) is an essential tool for industries that demand both reliability and durability in heavy-duty and high-temperature environments. This caster is engineered to withstand harsh conditions while offering smooth and controlled movement. The key features, such as its high load capacity, phenolic wheel construction, and precision Delrin bearings, ensure long-lasting, high-performance results for various industrial applications.
Designed to handle extreme temperature variations from -40°F to 600°F, this caster's phenolic wheel is made to perform in high-heat environments. The phenolic material provides excellent resistance to thermal degradation, making it ideal for industries such as food processing, pharmaceuticals, and other sectors where temperature stability is critical.
Equipped with full double ball hardened raceways, this caster ensures smoother movement and superior durability under heavy loads. The high-performance grease used is food-grade and FDA-approved, guaranteeing that the caster meets health and safety standards, even in food-related industries. The top lock brake (DTBRK7) allows for secure positioning in places where safety and stability are paramount.
The Delrin bearings provide minimal friction, enhancing the caster's lifespan and ensuring smooth and reliable operation even in demanding conditions. These bearings are known for their low maintenance requirements, making them an excellent choice for businesses looking for long-term, trouble-free performance.
With a load capacity of 800 lbs, this caster is designed to support heavy-duty equipment and machinery with ease. Whether used in manufacturing, warehousing, or any industrial setting, this caster ensures stability and strength under substantial weight, promoting safety and efficiency.
The caster features a 4" x 4-1/2" top plate, making it easy to install on various equipment and surfaces. The bolt hole pattern is designed to fit a wide range of mounting applications, with recommended plate bolt sizes of 3/8". This flexibility allows for quick and secure installation, minimizing downtime and maximizing productivity.
With a swivel radius of 4.94 inches, this caster is designed for smooth movement in tight spaces, offering excellent maneuverability even in congested work areas. This feature is especially useful in environments where quick, precise movements are required to improve workflow and efficiency.
Constructed from high-quality stainless steel, this caster is built to resist rust and corrosion, making it ideal for use in environments exposed to moisture, chemicals, and other corrosive elements. The stainless steel finish not only enhances the caster’s aesthetic appeal but also ensures that it remains functional and durable over time.
To meet specific application needs, the caster comes standard with a ½" diameter 304 stainless steel zerk axle, with the option for a solid axle available by special order. This flexibility allows businesses to tailor the caster’s functionality to their exact requirements.
The caster is backed by a 3-year warranty and is RoHS compliant. It also meets NSF component standards (excluding thread guards), ensuring that it adheres to strict safety and environmental regulations. This commitment to quality provides peace of mind to customers and ensures long-lasting value.
The D4.04109.331 HT BRK7 SS caster is ideal for a variety of industrial, commercial, and heavy-duty applications. Whether used in manufacturing plants, food processing facilities, or warehouses, this caster offers exceptional reliability and performance where it matters most.
This Colson D4.04109.331 HT BRK7 SS 4" x 2" Phenolic Stainless Side Lock Caster is rated to 800 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 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 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 5-5/8". 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).
