Ester-Based Greases
Ester-Based Greases
- The grease has a low viscosity ester oil base, which has outstanding low torque and low friction properties.
- The grease's exceptional lubricity lasts for long periods of time over a wide range of temperatures. This means that fewer grease reapplications are necessary, leading to resource conservation and reduced maintenance costs.
Recommended For:
- Bearings in electric machinery designed to reduce energy and current usage, and on high speed conveyance linear motion devices and ball screws.
- Machine tool spindles and other bearings that revolve at high-speeds.

26mm2/s | 1,236N | −50 〜 +150℃ |
Long-life/energy saving grease for ball bearings. As the grease has low oxidative degradation and low oil evaporation rates at high temperatures, and maintains stable torque even at extremely low temperatures, it can be used over a wide range of temperatures. For use on bearings in electric machinery and linear motion devices/ball screws. |
