High‑Speed Spindle Bearing Grease, Water‑Resistant Anti‑Wear Calcium‑Soap Lubricant
This dynamic lightweight grease combines good load‑carrying capacity, excellent water resistance and reliable anti‑wear protection. It achieves ultra‑high speed factor up to 1,300,000 mm/min while keeping low friction torque, lowering bearing temperature rise during continuous high‑speed running. Even under ‑50 ℃ cold conditions, it maintains good fluidity for smooth cold startup and energy saving.
Performance characteristics
- Ultra‑high‑speed performance: Speed factor up to 1,300,000 mm/min, stable lubrication for high‑speed spindle and rolling bearing systems
- Excellent low‑temperature property: Reliable fluidity at‑50℃, low starting torque, energy‑saving for cold‑environment equipment startup
- Superior water‑resistance & anti‑wear: Special calcium‑soap formula, good water repellency and wear protection, extend bearing service life
Low friction & low heat generation: Low friction coefficient reduces heat build‑up under continuous high‑speed rotation
Good load‑bearing capacity: Suitable for moderately‑loaded ball screws, threaded spindles and tapered roller bearings
Stable short‑fibre texture: Homogeneous grease structure, good mechanical stability, not easy to soften or leak under dynamic operation

Application
Machine tool spindle systems: Spindle bearings, tapered roller bearings for high‑speed machine tool units
Precision drive components: Threaded spindles, moderately‑loaded ball screws, precision gear tooth surfaces
Textile high‑speed equipment: Spinning turbine bearings operating under continuous ultra‑high‑speed conditions
General industrial high‑speed bearings: Plain & rolling bearings exposed to moisture, requiring water‑resistant anti‑wear lubrication and direct sunlight.
■ Apply grease evenly to gear teeth and contact surfaces.
■ Use an appropriate amount to ensure full coverage without excess.
■ Apply manually or through a lubrication system.
■ Run equipment at low speed after application to ensure proper distribution.
