The R-52HK-4HNY Hamilton High Heat Rigid Caster is an epitome of engineering excellence and robust design. Specifically tailored for challenging industrial conditions, this caster promises not just movement but seamless operation even in high-temperature environments.
Rated to withstand temperatures of up to 550° F, this Hamilton swivel caster is suitable for applications where most other casters would fail. Whether it's in a foundry or a high-heat oven setting, it stands resolute against the challenge.
The 4" x 2" Scorcher Wheel isn't just a wheel; it's a promise of durability and smooth movement. The perfect blend of materials ensures that the caster can move effortlessly, bearing the weight of heavy machinery without wear and tear.
The 3/4" Roller Bearing, fortified with high heat grease, guarantees the caster's longevity. This crucial component ensures smooth operations, reduces friction, and maximizes the caster's lifespan.
With the R-52HK-4HNY Hamilton Rigid Caster, you're not just buying a product; you're investing in quality, durability, and performance. Elevate your industrial operations and experience the Hamilton difference.
This Hamilton R-52HK-4HNY 4" x 2" Scorcher Rigid Caster – 550° F is rated to 800 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 Nylon wheel with a 2" tread width. Nylon resists chemicals and moisture and carries high loads, which suits washdown and wet environments.
This caster uses a top-plate mount with a 4" x 4-1/2" plate. 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 Up to 550°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 Nylon wheel performs best on smooth, hard industrial floors. 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).
