| Note: maximum permissible speed vmax |
In case of prolonged periods of use at speeds above 1 m/s, an increase in temperature and reduction in service life is to be expected depending on the load.
|
| Note: permissible operating temperature (min. ... max.) |
At temperatures above 100 °C, only bright metal ball transfer units 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.
