All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

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.
