47, 65, 70, 75, 76, 85, 95, 125 SERIES KINGPINLESSTM CASTERS 350-40,000 lb. Capacity

The 47, 65, 70, 75, 76, 85, 95 and 125 Series Casters are RWM Kingpinless™ Casters. We patented this design and it has proven itself to be the best solution for demanding applications. This is the caster design that all others are now copying because it is simply unmatched in extending service life, reducing all possible causes for caster failure.

RWM's patented Kingpinless™ caster design is superior due to the offset precision-machined raceway that exerts radial force evenly where there is full contact between the ball bearing and the raceway. The result is that there are no direct "hammering" forces on the intersections of the raceways, vastly reduced raceway wear, elimination of the "pull apart" forces of stress in the swivel section, and smoother swiveling action. There is also high maneuverability, longer service life, less maintenance, extra impact resistance and high radial force absorption. Our unique Kingpinless™ design adds more mass at key points. This, plus more thorough heat treatment, provides additional strength and combats brinelling into the core material.

The inline positioning of the majority of our competitor's raceways creates a direct "hammering" effect via the ball bearings, which are centered on the tangent of the two raceways, thus savaging and eventually eroding the raceway. The inevitable result is a loose fit and progressive swivel failure. Even a double raceway configuration is subject to these same "hammering" hazards. The machining requirements of the competition to accommodate a swivel lock reduces strength, leading to premature fatigue, stress fractures of the raceway and eventual failure.

Kingpinless™ raceways

RWM Kingpinless™ casters function flawlessly, even at high speeds, without shimmy. Our swivel section tolerances are .017, compared with .030 for the competition. This differential represents the amount of play between the top plate and the swivel yoke. The more precise the machining is, the closer the tolerance; the closer the tolerances, the longer the service life.

Our Kingpinless™ raceways provide the additional mass necessary for a double weld on its legs, inside and outside, as opposed to the competition's single weld. Their machining process does not provide the necessary mass for a weld on the outside race. Tests prove that RWM legs have a 74% higher yield strength than the competition, and a 74% higher ultimate strength than the competition. RWM caster's carbon content, the essential ingredient for strength in steel, is nearly seven times higher than the competition. The steel in RWM caster's race is superior in its heat treatment - nearly 18% harder than the competition. As a result, the RWM welded-in race is nearly 20% better equipped to resist brinelling that the competition, and allows the swivel section to turn easily in the roughest applications.

The RWM heavy duty Kingpinless™ casters are very high quality heavy duty and extreme duty line of casters for various industries and applications. They are 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.

2-65, 2-75, 2-76, 2-85, 2-95, 2-125 SERIES KINGPINLESS™ DUAL WHEEL CASTERS

RWM's 2-65, 2-75, 2-76, 2-85, 2-95 and 2-125 Series Kingpinless™ Dual Wheel Casters feature all of the benefits of our patented Kingpinless™ raceway and twice the capacity load. See the information in the section preceding this one for details on the RWM Kingpinless™ caster benefits.

Dual wheel casters offer high weight capacities with minimal overall heights, better load distribution, floor protection and mobility than single wheel casters. This is a result of spreading the weight over a wider floor area while offing wheel differential action, resulting in less friction between the wheels and the floor, requiring less effort for the caster to swivel.

Dual wheel casters are 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, tractor pulled trailers, extreme duty platform trucks and material handling carts, air cargo and ground support equipment, storage tanks, gantries, heavy duty processing equipment, coliseum and gymnasium equipment, shipping and receiving carts, warehouse dollies, freight terminal dollies and carts, and other extra heavy duty applications.

SA (SHOCK ABSORBING) CASTERS

RWM's Shock Absorbing (SA Series) Casters reduce stress on wheels and rigs due to shock from rough surfaces. These industrial casters dampen and isolate shocks and vibration from rough surfaces to protect cargo or contents in a cart or equipment. Our Shock Absorbing Casters reduce noise caused by casters traveling over rough surfaces. These casters equalize the load over uneven terrain among four or more casters, thereby reducing overloads on casters and twisting of the cart or frame. Our Shock Absorbing Casters feature either vertical mount springs, outside mount springs or inside mount springs.

Our Stainless Steel Casters are ideal for wet or damp conditions and harsh environments that may rust or corrode standard zinc casters. These casters are well suited for rugged duty and are designed for wash-down applications such as food processing plants, food service equipment, large volume high temperature bakery and food cooking facilities, bakery and bread racks, slaughter houses, fisheries, seafood processing plants, stock and maintenance carts, ingredient bins, institutional service carts and equipment, hatcheries, pharmaceutical plants and laboratories.
