| 1) | In case of prolonged periods of use at speeds above 1 m/s, an increase in temperature and reduction in service life needs to be reckoned with depending on the load. |
| 2) | At temperatures above 100 °C, only bright metal load balls without a felt seal should be used. Make allowance for reduction in load capacity. Use high-temperature lubricant! Follow the manufacturer’s instructions! The existing lubricant oil may have to be washed out. |
At temperatures above 100 °C, only bright metal ball transfer units without a felt seal should be used. Note the reduction in load capacity! Use high-temperature lubricant! Follow the manufacturer’s instructions! The existing lubricant oil may have to be washed out.
