Dive deep into the specifications and unparalleled features of the S-WHS-4AZ Hamilton Stainless Steel Workhorse Swivel Caster — the industry's premier choice for durability and top-notch performance.
At the heart of its impeccable strength is its top-grade stainless steel construction. This design not only ensures its long-lasting durability but also offers high resistance to corrosion — making it perfect for challenging environments.
Equipped with a 4" x 2" Aqualite Polyolefin (75D) Wheel, the caster promises smooth and effortless movement across various surfaces. This wheel type is carefully chosen to optimize maneuverability, ensuring that the caster can handle substantial loads while still being easy to move.
The S-WHS-4AZ features a 3/4" Delrin Bearing, a mark of high quality in the industry. Delrin Bearings are widely recognized for their reliability, ensuring a low-friction motion and reducing the need for constant maintenance.
Beyond its technical specifications, the true testament to its superiority is its manufacturer — Hamilton. Known for producing quality products, this caster is another feather in Hamilton's cap. The combination of Aqualite Polyolefin Wheel and Delrin Bearing is meticulously designed to minimize surface damage, guarantee seamless motion, and reduce maintenance frequency.
Enhancing your operations with the S-WHS-4AZ Hamilton Stainless Steel Workhorse Swivel Caster means investing in performance, durability, and quality. Witness the difference it brings to the table today.
This Hamilton S-WHS-4AZ 4" x 2" Aqualite Polyolefin Swivel Stainless Caster is rated to 550 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 Polyolefin wheel with a 2" tread width. Polyolefin is economical, lightweight, washable, and resists water, oils, and many chemicals while carrying solid loads on smooth floors.
This caster uses a top-plate mount with a 4" x 5" plate and a 2-5/8" x 3-5/8" and 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 caster. Swivel casters rotate 360 degrees for full maneuverability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -20°F to 200°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 Polyolefin 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 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).
