Ergo GT Elastomer Wheels
Heavy Duty Wheels
RWM Caster’s GT Solid Elastomer Wheels are high-performance wheels made from a tough blend of elastomers with the advanced wheel design to carry heavy loads without component breakdown. These heavy-duty wheels will resist most chemicals in industrial and institutional environments.
GT wheels will perform continuously for extended periods on all surfaces and under all conditions. This wheel provides excellent rollability with minimum effort. It will absorb impacts without damage that would shatter other wheels. The GT will perform under the most extreme temperatures almost entirely maintenance-free, and will roll mile after mile with virtually no tread wear.

- Performs continuously for very extended periods
- Works on all surfaces and under all conditions
- Absorbs impacts without damage that would shatter other wheels
- Continues to perform under the most extreme temperatures
- Rolls mile after mile with virtually no tread wear
- Performs almost entirely maintenance free
- Will not develop flat spots
- Non-marking
- One piece construction
Increased Capacity
The GT Wheel’s premium blend of high strength/high-performance elastomers, plus its state-of-the-art wheel architecture combine to provide 5%-15% more capacity than any other solid elastomer wheel available on the market.
Chemical Resistance
The GT Wheel is immune to practically every chemical currently in use in industrial/institutional environments.
Improved Rollability
Probably the most important aspect of day-to-day wheel usage is rollability. In tests involving rolling effort for two swivel casters carrying a load of 1150 pounds per caster, the GT Wheel was matched against the competition in a straight line pulling effort: 90 degrees to the direction of travel and 180 degrees to the direction of travel. Both wheels were elastomer, were equipped with precision ball bearings and were mounted into identical caster frames. The results of the tests as measured by a computer using a load cell clearly indicate that the GT Wheel provides momentum and maneuverability at half the effort – see the chart below:
| Wheel | Load Pounds | Straight Line | 90 Degree Start | 180 Degree Start |
|---|---|---|---|---|
| RWM GT Wheel | 1150 | 9 | 14 | 21 |
| Competitor | 1150 | 17 | 34 | 27 |
Superior Endurance
RWM engineers subjected the GT Wheel to a battery of exhaustive tests on both smooth and rough surfaces, as well as on a metal obstacle testing machine designed to simulate the most challenging workplace conditions. Here are the results of those tests:
- In continuous rolling tests – at a maximum capacity, and at three miles per hour – the GT Wheel outperformed competitors by a four-to-one ratio, rolling on and on while competitors’ wheels literally melted.
- The same four-to-one ratio also applied to obstacle test, proving conclusively that the GT Wheel is not only the most maneuverable wheel on the market, but also the most durable wheel on the market.
Reduced Tread Wear
Following the grueling endurance test described above, and after many miles of continuous rolling under the most challenging conditions, a diameter measurement of the GT Wheel showed a minuscule wear factor of less than .007” or practically no wear at all.
Extended Temperature Performance
Most wheels melt or shatter at temperature extremes – but the GT Wheel provides sustained performance t temperatures ranging from -40 degrees F to +275 degrees F.
Impact Resistance
The GT Wheel’s unique combination of chemical composition and wheel design equipped to withstand vastly greater impacts than other wheels. While phenolic, hard rubber, cast iron, and thermoplastic constructions shatter, the GT Wheel rolls on effortlessly.
Ease of Maintenance
The GT Wheel’s one-piece design and sealed, precision ball bearing combine with a tremendous ability to resist the effects of water and chemicals to make it literally maintenance free.
The GT Wheel offers you the finest in-shop
Industrial and institutional transportation capabilities available anywhere! In addition to its many other applications, the GT Wheel’s ability to handle extremely heavy loads, to traverse both smooth and rough floors, and to sustain heavy impact without damage make it ideal for manual moving of equipment as well as for use in tow line applications.
The Original Design
The GT Wheels are now copied worldwide; however, the original design has never been improved upon. This is due to our competitors using cheaper materials that result in an inferior product. Meanwhile, RWM uses top quality materials as a standard for all GT wheels. Don’t purchase an inferior knock-off—contact RWM Casters for the proven winning solution.
From heavy-load wheels to elastomer wheels, custom casters with no flat spots, and more, RWM has all of your industrial wheel and caster needs covered.
