Caster selection guide
Five questions decide the right caster: load, floor, environment, movement and size.
Step 1 · Load
Calculate load per caster
On uneven floors one caster often lifts off the ground, so the load is shared by one caster fewer. Divide your total load (equipment + goods) by casters − 1, then add a factor for rough floors and ramps.

480 kg / caster
Suggested: APEX C-150 Series
Load ÷ (casters − 1) × floor factor
Step 2 · Wheel material
Match the wheel to your floor
| Material | Load | Strength | Best for |
|---|---|---|---|
| PU (Polyurethane) | High | Quiet, floor-friendly, wear resistant | Factories, warehouses, automobile lines |
| Nylon | High | Easy rolling, chemical & moisture resistant | Smooth floors, food & pharma |
| Cast Iron | Very high | Heat and impact resistant, longest life on rough floors | Heavy industry, foundries, hot areas |
| Rubber | Low–medium | Quietest, absorbs shocks, protects floors | Hospitals, hotels, offices |
| PU on Cast Iron core | Very high | Heavy load with floor protection | Die trolleys, heavy fixtures |
| Stainless Steel (SS) | Medium–high | Corrosion resistant, washdown | Food, pharma, marine |
STEP 3
Fixed, swivel or brake
Use two swivel casters at the push end and two fixed at the rear for easy steering. Add brakes wherever equipment must stay put.
STEP 4
Wheel diameter
Bigger wheels (150–300 mm) roll over cracks and cables with less effort. Small wheels (50–100 mm) keep equipment low.
STEP 5
Bearings & environment
Ball bearings for easy rolling, roller bearings for heavy loads. Tell us about heat, water, chemicals or washdown.
