The Hamilton R-GS-4SPB General Service Rigid Caster stands as a hallmark of quality and functionality in the world of industrial mobility. This caster features a 4" x 2" Ergo-Glide Polyurethane wheel, perfectly balanced on a robust cast iron core, ensuring not only durability but also a smooth glide across different floor types.
The Ergo-Glide wheel, with its 85A durometer rating, is crafted to provide a soft, yet resilient touch to the floor. This innovative design minimizes noise, protects against scuffs, and ensures a controlled, smooth movement under various load conditions.
Incorporating 1/2" sealed precision ball bearings, the R-GS-4SPB caster delivers outstanding maneuverability and ease of positioning. This precision engineering makes it an ideal choice for applications that require reliable and efficient movement.
The caster's adaptability makes it a perfect fit for a variety of settings, including warehouses, retail environments, and healthcare facilities. Its non-marking characteristic is particularly beneficial for indoor applications where floor care is essential.
Hamilton's commitment to quality is evident in every aspect of the R-GS-4SPB caster. From design to production, each caster is crafted to meet the highest standards of durability and performance, ensuring customer satisfaction and long-term reliability.
This caster runs a Cast Iron wheel with a 2" tread width. Steel / iron wheels give maximum capacity and durability on smooth, hard industrial floors and tolerate heat.
This caster uses a top-plate mount. 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 Cast Iron wheel performs best on smooth, hard industrial floors. 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).
