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.

The 8" x 2" Stainless Polyolefin Delrin Bearing Caster with Total Lock and 4" x 4.5" Plate (Model: D4.08109.831 BRK4 SS) is a high-performance caster designed to meet the needs of demanding industrial and commercial environments. With a robust stainless steel construction, it ensures long-lasting durability, making it suitable for heavy-duty applications where reliability is paramount. Whether used in manufacturing, warehousing, or food processing, this caster excels in maintaining smooth operation and superior performance in challenging settings.
The caster’s stainless steel frame provides excellent corrosion resistance, ensuring a long service life even in harsh or high-moisture environments. Stainless steel is renowned for its strength and durability, which means this caster can handle even the toughest workloads. The full double ball hardened raceways further enhance the caster’s performance, reducing wear and tear while maintaining smooth movement. Additionally, the FDA-approved food-grade grease, which operates effectively in temperatures ranging from -40°F to 600°F, ensures reliable lubrication for smooth rolling in various environmental conditions.
This caster supports a heavy load capacity of up to 900 lbs, making it an excellent choice for industrial equipment, large machinery, or carts carrying substantial weight. The Polyolefin wheel, with its 2-inch tread width, provides a balance of strength and smoothness, ensuring optimal performance on various surfaces, from smooth floors to slightly uneven terrain. The Delrin bearings significantly reduce friction, enhancing mobility and extending the caster’s lifespan by minimizing wear.
The Total Lock brake system (DTBRK4) provides an added layer of security, allowing the caster to lock both the wheel and the swivel mechanism at once. This prevents the caster from moving or swiveling, ensuring your equipment stays securely in place when needed. This feature is particularly valuable in environments where stability and safety are crucial, such as medical or heavy-duty industrial settings.
The caster features a 4" x 4-1/2" top plate with a bolt hole pattern of 2-5/8" to 3" x 3" to 3-5/8", making it highly versatile for installation on various equipment. The recommended 3/8" bolt size ensures a secure fit, preventing accidental loosening over time. This caster can be used in various applications, including carts, racks, and industrial machinery, providing reliable mobility for all kinds of heavy-duty setups.
This caster stands out for its combination of durability, load capacity, and versatility, making it an excellent choice for a wide range of industries. Whether you're looking for a caster that can handle heavy machinery, withstand extreme temperatures, or meet food-grade compliance, the D4.08109.831 BRK4 SS offers the reliability and high performance you need. With its corrosion-resistant stainless steel frame, smooth Delrin bearings, and total lock brake, this caster ensures both ease of use and security in demanding environments.
