What is a Torus Wheel?
Toroidal wheels, trademarked as Torus wheels, feature rounded tread and sealed precision ball bearings to provide easy turning under heavy loads. The tread is made from premium PTMEG urethane, a superior product to typical PPG urethane that other manufacturers use. With a higher tensile strength, elongation and break ratings, and other high-quality classifications, PTMEG is the preferred polyurethane for industrial wheels.
The Torus wheel also features a sturdy aluminum core, which serves as a lighter alternative to cast iron. The tread is chemically and mechanically bonded to the metal core to prevent tread separation. This ensures the longest possible service life from your Torus wheels, even in the most demanding, continuous use applications.
RWM offers four types of Torus wheels:
- Blue 92A measures 92 on the Shore-A Hardness Scale for long-lasting durability.
- Red 85A has slightly softer tread for improved noise reduction and dampening when these qualities are desirable.
- Grey 85A features an electrostatic dissipative (ESD) compound for use with sensitive electronics and other loads that could be damaged by static buildup.
- Black 70D measures 70 on the Shore-D Hardness Scale, making it the firmest tread option of all for maximum ergonomic benefit.
These tread styles are available in wheel sizes ranging from 4 to 8 inches to meet a variety of needs.
Applications for Torus Wheels
The original Torus application was on automotive manufacturing assembly lines, but Torus wheels are highly suited for any continuous towline application across various industries, including aerospace, marine, foundry, military, molding, and others. Torus wheels are designed to withstand temperatures ranging from -40 to 180 degrees F. Load capacities range from 700 to 1500 lbs, depending on the wheel size.
