2-85 Series Casters

KINGPINLESS DUAL WHEEL CASTERS

RWM’s 2-85 Series Kingpinless™ Dual-Wheel Casters feature all of the benefits of our patented Kingpinless™ raceway and offer twice the capacity load. 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 offering wheel differential action, resulting in less friction between the wheels and the floor, requiring less effort for the caster to swivel. Our 2-85 Series Casters are proudly made in the U.S.!

Features & Advantages of 2-85 Casters

There are many benefits to choosing RWM’s 2-85 Kingpinless Casters for your applications. Among the most important is wheel selection. The 2-85 Series pairs greatly with many of RWM’s wheels, including Durastan, solid urethane, urethane on iron, cast iron, Nylatron HD, forged steel, rubber on iron, and more. Further, we manufacture the casters to pair with wheels with 6-, 8-, 10-, 12-, 14-, or 16-inch diameters with 3- to 5-inch wheel widths. This allows you to select a caster with a capacity of up to 10,000 pounds.

This gives you a considerable advantage because it makes it possible to select a caster with the ideal weight and carrying capacity. Moreover, it makes it possible to select a caster that is ideally suited for your operational environment. This reduces wear and tear, will prolong the serviceable life span of your caster, and makes it easier for your employees to safely and efficiently move everything from raw materials to finished products.

Customization Is Key

Effective and efficient operation depends on the customization of the components within your systems. At RWM, we make it easy to create customized casters tailored to your specific needs. We offer numerous customizable options that allow you to choose cam wheel brakes or poly cam wheel brakes, 8-position swivel locks, L-type swivel locks, high-temperature or low-temperature lubrication, and more.

We’ll help you navigate your options and will create a custom caster that will deliver exceptional performance for your needs. Contact RWM Casters at (800) 634-7704 to speak with our team about your specific needs.

To order a rigid caster, change the “S” to “R” in the model number. For example: “2-85-CIR-1040-R”. To order rig only, omit the blue letters. For example: “2-85-1040-S”. Dimensions shown are nominal. If precise dimensions are required, consult your RWM representative. For approximate weight of our rigid
casters, deduct 5.4 pounds per item.
