Mobil Velocite Oil No. 3
ISO VG 2 Spindle Oil for Zero-Clearance Machine Tool Bearings
Mobil Velocite Oil No. 3 is an ISO VG 2 spindle oil designed for high-speed machine tool bearings with extremely close clearances. Also searched as Mobil Velocite No. 3 or Mobil Velocite Oil Number 3, this very low-viscosity machine tool lubricant is part of the Mobil Velocite Oil Numbered Series.
Mobil Velocite No. 3 is specifically recommended for “zero clearance” type spindle bearings that operate with very tight tolerances. This ISO VG 2 spindle oil helps support oil flow in fine-clearance areas while providing oxidation resistance, rust and corrosion protection, foam control, and water separation.
For machine shops, maintenance teams, and precision equipment operators, Velocite Oil No. 3 is a practical choice when the equipment manual calls for an ISO VG 2 spindle oil, high-speed spindle oil, or very light machine tool lubricant.
Key Benefits
- ISO VG 2 spindle oil for extremely close-clearance bearings
- Recommended for “zero clearance” type spindle bearings
- Designed for high-speed machine tool applications
- Helps support lubrication in fine-clearance areas
- Helps reduce deposit formation through oxidation resistance
- Helps protect metal surfaces from rust and corrosion
- Separates readily from water to support moisture removal
- Provides very good resistance to foaming
Recommended Applications
This low-viscosity spindle oil may be used in:
- Zero-clearance spindle bearings
- High-speed machine tool spindles
