Engineering Specifications
Wheel & Bearing
  • Wheel size: 8" diameter × 2" tread width
  • Tread: Mold-on rubber, 70A durometer
  • Core: Cast iron
  • Bearing: 3/4" straight roller bearing
Performance & Compliance
  • Load rating: 600 lb (per caster)
  • Caster type: Swivel
  • Compliance: NSF Listed (where specified)
  • Best use case: Heavy rolling loads needing traction + durability

Note: Real-world capacity depends on floor condition, duty cycle, obstacle impacts, and load distribution across all casters. For critical systems, use an engineering safety factor.

Typical Applications
Industrial carts & material handling
Good fit for plant carts, kitting carts, and transport fixtures where controlled rolling and durability are required.
Hospitality & food-service equipment (NSF-driven)
Commonly selected for environments where NSF listing matters and equipment must roll smoothly with predictable traction.
Maintenance / MRO platforms
Useful for tool platforms, maintenance rigs, and shop equipment where rubber tread helps reduce chatter on uneven surfaces.
Staging, fixtures, and racks
Suitable for heavy racks/fixtures that require swivel maneuverability and stable rolling characteristics.
Selection Notes (Engineering)
Why mold-on rubber on cast iron
  • Rubber tread improves traction and helps reduce vibration vs. all-metal wheels
  • Cast iron core supports high durability under rolling load
  • Good compromise between floor-friendliness and long service life
When to choose something else
  • If you need maximum chemical resistance → consider phenolic/nylon options
  • If you need the quietest roll → consider softer tread materials (with capacity tradeoffs)
  • If you have frequent thresholds/debris → consider wheel size and bearing protection strategy
FAQs
Is the 600 lb rating per caster or per set?
The 600 lb rating is per caster (unless otherwise stated). Total system capacity depends on the number of casters and real-world load distribution.
What does 70A durometer mean in practice?
70A rubber is a medium-hard tread commonly used to balance traction and durability. It typically rolls smoother than hard plastics while remaining robust for industrial use.
Is this caster good for uneven floors?
Mold-on rubber can help reduce vibration on imperfect surfaces, but severe floor defects/thresholds still require proper wheel diameter, load margin, and sometimes alternative wheel material selection.
How do I choose between the premium configuration and the more affordable standard option?
If cost is the main driver and your application does not require upgraded construction details, choose the standard listing here: Standard 8" × 2" Swivel Mold-On Rubber — 600 lb — NSF . If your use case is high duty-cycle, high impact, or requires a specific bearing/wheel build, use the configuration that matches your spec.

Frequently Asked Questions

What is the load capacity of this caster?+

This Hamilton S-628-R 8" x 2" Mold-On Rubber Swivel Caster – 600 lb is rated to 600 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.

What wheel does this caster use?+

This caster runs a Rubber wheel with a 2" tread width. Rubber absorbs shock and protects floors, and runs quietly, which suits noise-sensitive and light-to-medium duty use.

What plate size and bolt pattern does it use?+

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.

Is this a swivel or rigid caster, and how does the brake work?+

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.

What temperature range can this caster handle?+

Rated for Up 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.).

What floors and applications is it best for?+

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.

How do I order, and what are the terms?+

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).
