Shell Alvania R3 Grease Datasheet Extra Quality ((new)) ❲720p❳

Short story — "Shell Alvania R3: The Datasheet That Saved the Day"

When the old press in Bayport Groundworks began to squeal in the second shift, the foreman, Mara, knew it was more than a loose bolt. Machines whisper problems before they shout them, and this one was singing a song of dried bearings and overdue lubrication.

Due to its Grade 3 stiffness and high-temperature tolerance, it is specifically recommended for: shell alvania r3 grease datasheet extra quality

: Specifically optimized for bearings operating at their maximum rated speeds within the stated temperature range. Oxidation and Mechanical Stability Short story — "Shell Alvania R3: The Datasheet

Do not discharge into drains, soil, or water. Dispose of used grease at authorized collection points. Composition: Penetration (Worked): 235 means it's firm enough for

The Extra Quality variant also includes advanced anti-oxidants and tackifiers, reducing hardening and bleed.

  1. Penetration (Worked): 235 means it's firm enough for vertical shafts. If your application is horizontal and slow-speed (<500 RPM), you could also use NLGI 2, but NLGI 3 reduces leakage.
  2. Base oil viscosity (105 cSt @40°C): Ideal for bearing speeds (DN factor up to 150,000). For DN >200,000, select a lower-viscosity base oil (e.g., Shell Alvania S2).
  3. Operating temperature limit: Do not exceed 110°C continuous. If your bearing housing runs at 120°C, you need a polyurea or calcium sulfonate grease.

3.2 Enhanced Water Resistance

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.
