High temperature resistance
In the below table the temperature ranges are shown for particular wheel types. Greasing the wheel bearing allows it to operate within the temperature range from -20°C to +120°C. For higher temperatures the use of some special grease is required. Heat resistant wheels are also made to special customer orders.
| Wheel composition | Wheel - application | Periodically up to 10 minutes | ||
|---|---|---|---|---|
| Rubber | -20°C | +60°C | -30°C | +80°C |
| Polyurethane | -20°C | +80°C | -40°C | +100°C |
| Polypropylene | -20°C | +60°C | ||
| Polyamide | -30°C | +80°C | -30°C | +110°C |
| Bakelite | -30°C | +250°C | -40°C | +300°C |
| Vulkollan | -40°C | +85°C | -40°C | +100°C |
| Thermoplastic elastomer | -20°C | +60°C | ||
