The RM-Clean series builds the bracket, axle and (optionally) the wheel in stainless steel, so the caster survives washdown, salt spray and cleaning chemicals without seizing or rusting.
Typical applications: food processing lines, cold storage, pharmaceutical cleanrooms, medical equipment and marine-adjacent environments.
Material Grades & Properties
Stainless Steel Grades We Machine
| Grade | Standard | Characteristics |
|---|---|---|
| SS304 | brackets & wheels | standard washdown |
| SS316 | brackets & wheels | chloride environments |
Key Properties of Machined Stainless Steel
- ✓No plating to fail in washdown
- ✓Salt spray tested in house
- ✓Material certificates on request
Typical tolerances:Swivel torque tested per batch
Applications for Stainless Steel Parts
- food processing

Finishes
Passivated stainless steel
| Bracket finish | What it does | Specify it when |
|---|---|---|
| Zinc plating (blue/white) | Baseline corrosion protection | Standard dry indoor use |
| Chrome plating | Hard, decorative, easy to clean | Visible / cleanroom-adjacent equipment |
| Powder coating | Custom color, good corrosion resistance | Brand colors, outdoor-adjacent use |
| Stainless steel 304 | No plating to fail | Washdown, food, medical |
| Stainless steel 316 | Resists chlorides | Salt, brine, marine air, harsh cleaning chemicals |
Testing
Salt spray test chambers on site; material certificates on request
| Selection factor | Rule of thumb | Effect on performance |
|---|---|---|
| Load sizing | Total load ÷ 3 (not ÷ 4) | On uneven floors only three wheels carry the cart |
| Wheel diameter | Bigger rolls easier | Larger wheels cut push force and bridge gaps |
| Tread hardness | Softer = quieter, harder = easier rolling | Pick the softest tread that carries the load |
| Bearing choice | Precision ball for manual pushing, roller for heavy loads | Bearings dominate rolling resistance at high load |
| Swivel vs rigid | 2 swivel + 2 rigid is the standard cart setup | All-swivel carts wander; all-rigid carts cannot steer |
| Floor condition | Rough floors need bigger wheels and softer treads | Small hard wheels on bad floors destroy both |
