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.
PRODUCT CODE: D4.08109.935-KW-BRK4-SS
The Colson D4.08109.935-KW-BRK4-SS is a 8" x 2" solid polyurethane plate-mount caster rated Supports up to 1250 lb, ideal for heavy per caster, mounted on a 4" x 4-1/2" plate. It is built for industrial use where part-number-exact specification, capacity, and bearing life take priority. The 8" diameter rolls cleanly over expansion joints and floor seams smaller wheels stall on. In stock at CasterHQ Mansfield, TX with same-day shipping on quantities of 1-100 placed before 2:00 PM Central. BAA / TAA documentation available on request for federal, defense, and aerospace procurement.
I spec Colson on standard-duty industrial carts where bearing life and quiet roll matter more than maximum capacity. The D4.08109.935-KW-BRK4-SS earns its place when smooth-roll quiet operation and floor protection are the controlling spec. Pair 8" on the steered axle with a matching rigid version on the trailing axle for true four-position cart kinematics. If your floor has expansion joints over 1/2" wide, step up to a larger wheel diameter.
Colson encodes its part numbers by series, wheel material, wheel diameter, plate size, bearing type, and mount style. The D4.08109.935-KW-BRK4-SS is decoded by your CasterHQ engineer at order time — call us at 844-439-4335 for a full breakdown.
Supports up to 1250 lb, ideal for heavy per caster dynamic. On a 4-caster cart with even load distribution and a 1.3x safety factor for moving loads, that yields the rated working capacity per cart.
Yes for cast iron and steel wheels. 8" diameter rolls over expansion joints and seams cleanly. For polished or epoxy floors, ask us about poly-on-iron or thermoplastic options.
Colson's industrial casters are USA-manufactured. We provide BAA/TAA-compliant Country-of-Origin documentation on request for federal procurement, typical turnaround under 24 hours.
