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 Colson D4.06108.935-KW-SS is a 6" x 2" k solid polyurethane plate-mount caster rated 1250 lb per caster, mounted on a 4" x 4.5" Top Plate plate. It is built for industrial use where part-number-exact specification, capacity, and bearing life take priority. The 6" 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 D4.06108.935-KW-SS earns its place when smooth-roll quiet operation and floor protection are the controlling spec. Pair 6" 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 D4.06108.935-KW-SS is decoded by your CasterHQ engineer at order time — call us at 844-439-4335 for a full breakdown.
1250 lb 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. 6" diameter rolls over expansion joints and seams cleanly. For polished or epoxy floors, ask us about poly-on-iron or thermoplastic options.

With advanced materials, precision engineering, and compatibility across various setups, this caster is the premium choice for businesses that prioritize reliability and quality in their equipment.
This Colson D4.06108.935-KW-SS 6" x 2" K Solid Polyurethane Caster — 1250 lb is rated to 1250 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 Solid Polyurethane wheel with a 2" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.
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 Rigid caster. Rigid casters track straight for directional stability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -20°F to 180°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 Solid Polyurethane wheel performs best on smooth to semi-smooth floors including sealed concrete, tile, and epoxy. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 7.5". 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).
