3. NLGI Grade Selection Guide & Applications
| NLGI Grade | Consistency | Recommended Applications |
|---|---|---|
| NLGI 000 / 00 | Semi-fluid / Fluid | Centralised automatic lubrication systems, enclosed gear housings, worm gears, large slow-speed open gears |
| NLGI 0 | Very Soft | Slow-speed heavily loaded plain bearings, large rolling element bearings, centralised grease distribution systems |
| NLGI 1 | Soft | Rolling element bearings at low–moderate speeds, electric motor bearings, conveyor and idler bearings |
| NLGI 2 | Normal / General Purpose | General-purpose industrial and automotive bearings, wheel bearings, chassis, universal joints — most standard applications |
| NLGI 3 | Firm | High-speed bearings, vertical shaft bearings, applications prone to grease leakage or migration |
4. Performance Features & Benefits
- Lithium soap thickener — proven, widely compatible, and cost-effective for general industrial service
- Solvent-refined mineral base oil — excellent lubrication film strength across the full NLGI 000–3 range
- Effective EP additive package — passes Four-Ball Weld ≥ 250 kg, protecting heavily loaded contacts under shock and sustained load
- Anti-wear (AW) additives — reduces wear on rolling elements, raceways, and sliding surfaces
- Rust and corrosion inhibitors — protects ferrous and non-ferrous metals in humid and wet environments
- Antioxidant package — extends grease service life and resists oxidative thickening in storage and service
- Good water resistance — low water washout values across all grades; suitable for moderately wet environments
- Wide NLGI range (000–3) — single product family covers fluid gear lubrication through firm bearing grease, simplifying inventory
- Compatible with most standard sealing materials (NBR, FKM)
- Suitable for use in centralised automatic lubrication systems (NLGI 000–1)
