Shell Alvania G3 Data Sheet
The Roll Stability test shows a penetration change of +30 max. This means Alvania G3 softens very little under shearing forces. In vibrating or high-torque applications, the grease retains its consistency and does not turn into a liquid run-off.
A common confusion exists between Alvania G2 (NLGI 2) and Alvania G3 (NLGI 3) . Here is a quick comparison:
| Property | Alvania G2 | Alvania G3 | |----------|------------|-------------| | NLGI Grade | 2 | 3 | | Penetration (worked) | 265–295 | 220–250 | | Flowability | Semi-fluid, easy to pump | Firm, requires positive displacement pump | | Best for | Horizontal shafts, centralized systems | Vertical shafts, vibrating screens, slow bearings | | Low temp limit | -25°C | -20°C |
Practical advice: Use G3 when G2 tends to run out too quickly. Use G2 when G3 is too stiff to reach the bearing through long grease lines. shell alvania g3 data sheet
It provides a protective barrier against moisture and corrosive elements, making it suitable for outdoor equipment or environments where humidity is a factor.
Shell Alvania G3 is a light, high-performance grease formulated for lubrication of plain and rolling element bearings in automotive and industrial applications. It typically uses a lithium complex thickener and a synthetic/base oil blend, offering good mechanical stability, water resistance, oxidation stability, and protection against wear and corrosion.
A: No. For food processing, use Shell Cassida Grease series. The Roll Stability test shows a penetration change
| Property | Value | Implication | |----------|-------|--------------| | Thickener | Lithium complex | Excellent mechanical stability, high dropping point. | | NLGI Grade | 2 | Standard consistency; suitable for most centralized systems and bearings. | | Dropping Point | >260°C (500°F) | High temperature capability before liquefying. | | Operating Temperature | -20°C to 150°C (-4°F to 302°F) | Broad range; intermittent use up to 150°C. | | Base Oil Viscosity (40°C) | ~150 cSt | Medium-viscosity oil – good film strength for normal to slightly heavy loads. | | Base Oil Type | Highly refined mineral oil | Good oxidation resistance, but not synthetic. | | 4-Ball Weld Load (ASTM D2596) | ~260-280 kg | Moderate extreme pressure (EP) performance. | | Water Washout (79°C) | <5% loss | Excellent resistance to water washout. | | SKF EMCOR (Rust) | 0-0 (pass) | Excellent corrosion protection in fresh/salt water. |
