Rigid casters do not swivel — the cart travels straight. In the classic two-swivel + two-rigid setup they give stability and tracking while the swivels steer.
Because a rigid bracket has no raceway, it carries more load and needs less force than the same-size swivel: heavy carts often run one swivel pair and a rigid pair.
The practical rule: the more of the cart travel is straight-line, the more rigid casters pay back. Long aisle runs, towed trains and rail-guided carts are the natural cases; tight multi-turn maneuvering needs swivels.
Spécifications
- Higher load rating than same-size swivel versions
- Welded rigid brackets, plate or bolt-hole mounting
- Same wheel options as the swivel line
- Directional lock swivels available where full rigid is too inflexible
Finitions
Zinc, powder coat, stainless
| 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 |
Essais
Axle and bracket alignment checked per batch
| 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 |
