The Hamilton Workhorse Rigid Caster (R-WHS-4SWC85) embodies superior engineering with an impressive 720-pound load capacity. Crafted from high-grade stainless steel, this caster is designed for dependable heavy equipment transport, featuring a robust twin wheel design for balanced weight distribution and enhanced operational safety.
With the 4" x 2" UltraGlide twin wheels, enjoy a seamless and quiet movement without sacrificing the strength required for demanding tasks. The wheels' blue tread paired with an aluminum core not only safeguards your flooring but also adds an aesthetic dimension to your industrial space.
Each swivel caster comes equipped with 3/4" sealed precision ball bearings, specifically designed to minimize friction and facilitate smoother motion. The maintenance-free, sealed bearing design ensures durability and uninterrupted performance.
The Hamilton Rigid Caster thrives in severe temperatures, enduring both intense cold and extreme heat, which positions it as the versatile choice for diverse industrial applications, no matter the environmental conditions.
Designed for resilience, this caster boasts a high impact resistance rating, superior abrasion resistance, and medium chemical and moisture resistance, ensuring long-term preservation of its form and function in various challenging conditions.
The Hamilton Stainless Steel Workhorse Rigid Caster is more than a mere component; it's a cornerstone of efficient, safe, and reliable workflows. Ideal for strenuous applications from manufacturing to logistics, it promises to perform seamlessly every time.
This Hamilton S-WHS-4SWC85 4"x2" UltraGlide Rigid Stainless Caster – 720 lb is rated to 720 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 Polyurethane wheel with a 2" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.
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 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.
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).
