💡 What technical factor determines how much weight a polyurethane caster can actually carry?
Structural integrity dictates the maximum static load rather than simple tire volume.
- Industrial operators match roller bearings to stationary platforms because they distribute point heavy loads evenly across the pin.
- Logistics coordinators trust the forged aluminum housing to maintain plate alignment so the cart frame does not torque during movement.
- Facility managers count on the domed polyurethane composition to spread impact friction across hard tile to prevent sidewall cracking.
