The springs in these casters take on bumpy surfaces and obstructions while preventing shock to the load.

A forged-steel frame and air-filled tire absorbs shock to prevent damage to your load.

The solid rubber wheels on these casters cushion as well as pneumatic wheels but won't go flat.

A tough, puncture-resistant tread surrounds a nonpressurized pocket of air so these wheels absorb shock to cushion like pneumatic wheels but won't go flat.

Quiet-rolling air-filled rubber tires cushion your load when rolling over rough or uneven surfaces.

These wheels have a webbed tread that flexes to absorb shock and tapered roller bearings to withstand both downward and side force.

Also known as balloon tires, these have a rounded, cushioned tread for easy turning and good shock absorption.

Also known as semi-pneumatic wheels, these have a tough, puncture-resistant tread surrounding a nonpressurized pocket of air to cushion like a pneumatic wheel without going flat. Their spoked hub keeps them lightweight at larger sizes.

The thick, solid rubber or polyurethane foam treads provide the cushioned ride of an air-filled pneumatic wheel without the possibility of a flat tire.

A stiff sidewall prevents swaying during towing. Wheels are filled with compressed air to provide the best shock absorption and a quiet ride.
