Frequently asked questions
Common questions about RWM from 3G Electric.
What is the difference between RWM kingpinless and standard plate casters?
RWM kingpinless plate casters eliminate the kingpin, using a swivel assembly with a ball bearing raceway that distributes load more evenly. This design reduces wear and provides smoother swiveling under heavy loads and shock conditions. Standard plate casters use a kingpin to hold the swivel assembly together. Kingpinless models are typically chosen for heavy-duty applications where durability and ease of movement are critical. RWM offers both types, with kingpinless models available in wheel diameters of 8 and 10 inches and mounting heights up to 12 1/2 inches.
What wheel materials are available for RWM general-purpose plate casters?
RWM general-purpose plate casters come with rubber, nylon, elastomer, and polyurethane wheels. Rubber wheels provide quiet operation and floor protection, suitable for smooth surfaces. Nylon wheels offer high load capacity and resistance to chemicals, ideal for hard floors. Elastomer wheels combine some properties of rubber and plastic, with good shock absorption. Polyurethane wheels resist abrasion and oils, often used in heavy-duty applications. Each material has specific load ratings and performance characteristics, and selection depends on floor type, load, and environment.
Are RWM maintenance-free casters suitable for washdown environments?
RWM maintenance-free casters are designed to reduce lubrication needs, but their suitability for washdown depends on the specific model and wheel material. Casters with sealed bearings and stainless steel components are better for wet environments, while standard models may not be. For washdown, consider casters with polyurethane or nylon wheels and sealed precision bearings. It is important to verify the IP rating or material compatibility for the intended cleaning chemicals and conditions. Consult the individual product specifications for details.
What is the load capacity of RWM heavy-duty kingpinless casters?
Load capacity varies by model and wheel material. For example, RWM heavy-duty kingpinless casters with 10-inch phenolic wheels and roller bearings can handle significant loads, often in the range of several thousand pounds per caster. The exact capacity depends on the wheel diameter, width, and bearing type. It is essential to refer to the specific product data sheet for accurate load ratings, as capacity is determined by the weakest component in the caster assembly. Always consider the application's dynamic loads and safety factors.
Can RWM plate casters be used on uneven floors?
RWM plate casters can be used on uneven floors, but performance depends on wheel material and diameter. Larger wheels, such as 8-inch or 10-inch diameters, roll over obstacles more easily than smaller ones. Rubber or elastomer wheels provide some shock absorption and conform better to minor floor irregularities. For severely uneven surfaces, consider casters with spring-loaded or shock-absorbing features, though RWM's standard line may not include these. Kingpinless swivel casters maintain better contact and steering on uneven floors compared to kingpin models.
