The grease contains oxidation inhibitors that resist thickening and the formation of sludge over long periods of use. This "extra quality" oxidation stability means longer re-greasing intervals and reduced downtime for maintenance.
Note: This is NOT an NSF H1 food-grade grease. For food processing, refer to Shell Gadus S2 V220 series.
When a datasheet specifies "Extra Quality," it refers to production batches that meet stricter internal tolerances than the industry minimums (DIN 51825 or ISO 6743-9). For Shell, this implies: shell alvania r3 grease datasheet extra quality
Understanding the Shell Alvania R3 grease datasheet extra quality is critical for buyers who cannot tolerate batch variation in food-grade adjacent or precision bearing environments.
In high-vibration environments (e.g., rock crushers or vibrating screens), standard greases can thin out, leading to leakage. Alvania R3 Extra Quality retains its NLGI 3 consistency even after 100,000 shear cycles. This translates to: Note: This is NOT an NSF H1 food-grade grease
The Extra Quality variant undergoes a more rigorous water washout test. At 79°C, standard greases might lose 4-5% mass; Extra Quality loses less than 3%. For applications like agricultural equipment or marine deck machinery, this is a decisive factor.
Using the RPVOT method (ASTM D2272), Extra Quality batches recorded pressure drop times exceeding 180 minutes at 150°C, compared to 140 minutes for standard. This means: When a datasheet specifies "Extra Quality," it refers
Water washout is a leading cause of bearing failure. Shell Alvania R3 has excellent water resistance properties. It does not easily wash out of bearings, making it an ideal choice for marine applications, paper mills, or outdoor equipment exposed to the elements.
