G Series Kingpinless Heavy Duty Industrial Casters

Capacities up to 6,000 pounds per rig for demanding operations

These are large, high-capacity casters, with multiple wheel options up to 3" wide and overall heights to 12-1/2". The G series is case-hardened for extended service life, and will not crack like flimsier, through-hardened or induction-hardened casters. Kingpinless design means they swivel better under massive loads and last longer. Beefier legs and extended leads make G Series an excellent option for towing operations in heavy-duty, demanding applications such as automotive assembly plants and tire manufacturing.

Wheel types

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.

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.

A mainstay in tire manufacturing (and many other applications):

Typical applications include dollies, utility carts, tow line and platform trucks. This caster is also ideal for: tow lines, shock load applications and abusive conditions, production line dollies and trucks used in various industries including but not limited to: boat and ship molding and building, automotive, aerospace, metal fabricating, metal forging, heavy machinery and equipment, military equipment, mobile homes, etc. Tractor pulled trailers, extreme duty platform trucks and material handling carts, air cargo and ground support equipment, storage tanks, gantries and heavy duty processing equipment, coliseum and gymnasium equipment, shipping/receiving carts, warehousing and freight terminal dollies and carts, and countless other heavy duty applications.

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 our casters use) 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
