Description
UNIREX™ N3 grease is a premium-quality, lithium-complex product suitable for high-temperature service in rolling-element bearings
- These versatile greases can be used in a wide range of industrial applications and are particularly recommended for electric-motor lubrication.
- Unirex N greases exhibit excellent high and low temperature performance, resistance to water and corrosion, and long service life in a range of bearing applications.
- UNIREX N greases are not intended to be used under extreme pressure conditions where extra anti-welding properties are required.
- UNIREX N 3 meets the requirements of Lubricating Grease DIN 51825 – K3N – 20L and ISO L-XBDHA 3
Applications
- Most of the uses for UNIREX N involve manual methods of application.
- Although UNIREX N 2 is suitable for use in automatic centralized systems, equipment served by these systems would normally not require the long-life properties of UNIREX N, since one of the functions of automatic systems is to replenish the lubricant at relatively short time intervals. UNIREX N 3 should not be used in such systems.
Specifications
- DIN 51825 – K3N – 20L
- ISO 6743-9: 2003 L-XBDHA 3
Benefits
- Lithium-complex thickener resists softening / running out of bearings at temperatures up to 190°C
- Laboratory bearing rig tests show outstanding continuous lubrication performance at bearing temperatures of up to 140°C
- Start-up power requirements are low at temperatures down to at least -20°C. Meets DIN 51825 low temperature torque requirements at -20°C
- Exhibits excellent resistance to softening due to mechanical working
- Resists water washout and protects bearings against corrosion
- Channelling characteristics provide excellent performance in high- speed deep-groove ball bearings. Unirex N3 is recommended where DmN (mean bearing diameter X rpm) exceeds 360,000
