The R-8528-SU Hamilton Cush-N-Flex Rigid Caster is a remarkable representation of functional engineering, marrying agility and strength. It boasts a Super-Flex Rubber Wheel measuring 8" x 2-1/2". This design ensures flexibility without compromising on durability, thanks to its robust Aluminum core.
One of the standout features is the 3/4" Straight Roller Bearing, tailored for seamless movement, especially under considerable weight. The rigid design of the caster is ideal for enhancing mobility, allowing for fluid direction changes even in confined spaces.
The caster is explicitly crafted with industrial applications in mind. Its ability to function in demanding environments is noteworthy. Beyond its structural merits, the 60A Rubber Hardness strikes a balance - offering softness for optimal shock absorption and hardness for an extended lifespan.
A nod to sustainability, the materials used, particularly the recyclable rubber and aluminum, underline an eco-friendly commitment. Furthermore, the R-8528-SU Hamilton Caster is virtually maintenance-free, designed to serve for prolonged periods without necessitating constant attention or upkeep.
For those seeking a caster that effortlessly combines resilience, mobility, and eco-consciousness, the R-8528-SU Hamilton Cush-N-Flex Rigid Caster is a top-tier choice, promising both performance and longevity.
This Hamilton R-8528-SU 8" x 2-1/2" Super-Flex Rubber Rigid Caster is rated to 500 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 Rubber wheel with a 2-1/2" tread width. Rubber absorbs shock and protects floors, and runs quietly, which suits noise-sensitive and light-to-medium duty use.
This caster uses a top-plate mount with a 4" x 4-1/2" 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 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 -30°F to 250°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 Rubber wheel performs best on rough, uneven, or outdoor surfaces such as asphalt, gravel, and cracked concrete. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 9-1/2". 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).
