Wheel types

Cast iron

Cast iron wheels are exceptionally long wearing. They have tremendous resistance to shock and are a good choice for high capacity loads in warehousing and manufacturing. Recommended for rough concrete, wood block, and littered floors.

Ductile steel

Ductile steel wheels have very high weight capacities, heat resistance, and tensile strength, making them nearly unbreakable— even under shock loading and other exreme conditions. They should not be used on expensive factory floors or other protected surfaces, as they are likely to cause deterioration.

Thermoplastic rubber (TPR)

TPR wheels combine the durability of hard-tread wheels with the quiet floor protection of soft-tread wheels. They are made of thermoplastic elastomer, permanently bonded to a polypropylene core. They are non-marking and resistant to chemicals, acids, bases, alcohols, salts, and steam.

Phenolic

Phenolic wheels provide excellent service even in wet and cold applications. They resist degradation, deterioration, and corrosion from oil, grease, and commonly used acids and solvents. Recommended for all types of floors except resilient tiles.

Urethane on iron

Capacities rival those of steel wheels. Careful attention is paid during the bonding process to assure that each wheel meets high performance standards. UI wheels are non-marking and resistant to abrasion, chemicals, and oil. These wheels will typically outlast rubber wheels.

V-groove iron

V-Groove wheels are machined with a 90 degree groove for operation on inverted angle iron track. They are used to control the flow of a load (into an oven, between machines, over long distances, or where "production line" sequences must be maintained.)

The patented Kingpinless™ raceway eliminates the number one cause of caster failure

The offset precision-machined raceway exerts radial force evenly where there is full contact between the ball bearing and the raceway. A unique design adds more mass at key points. This extra mass, plus more thorough heat treatment, provides additional strength and combats brinelling into the core material.

This means longer, better service life in demanding industrial applications

The inline positioning of many competitive raceways (as opposed to the offset positioning in our casters) creates a direct hammering effect via the ball bearings, which are centered on the tangent of the two raceways, stressing, and eventually eroding the raceway. The inevitable result is a loose fit and progressive swivel failure. Even double raceways are subject to these hammering forces.

No direct "hammering" forces on the intersections of the raceways for vastly reduced raceway wear
Elimination of the "pull apart" forces of stress in the swivel section - a huge issue in towing applications
Smoother swiveling action and better maneuverability
Longer service life - maintenance is easier and less frequent
Extra impact resistance and high radial force absorption
