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.

These wheels consist of an air-filled rubber tire on a steel rim and are among the quietest, most shock-absorbing wheels available.

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.

These lightweight wheels are commonly used on carts. They are filled with compressed air to provide the best shock absorption and a quiet ride.
