Klüber ISOFLEX TOPAS L 152
Rolling bearing grease for a wide service temperature range
Application Klüber AISOFLEX TOPAS L 152
Application ISOFLEX TOPAS L 152 is used for rolling bearings, e.g. in electric motors where smooth running is required and a wide range of temperatures is to be covered, e.g. in traction motors. The grease can also be used for the main bearings in wind power stations and plastic/plastic or plastic/steel friction points. Axlebox bearings with line contact, e.g. railways. Applications requiring low starting torques at low temperatures.
Performance, Features & Benefits of Klüber ISOFLEX TOPAS L 152 are:
- Wide service temperature range and excellent low-temperature stability owing to the special synthetic base oil
- Recommended for roller bearings due to the adequate oil separation behaviour, particularly under sliding friction conditions
