Use the datasheet’s relubrication interval formula: Interval (hours) = 14,000 / (n × d^0.5) – where n = RPM, d = bearing bore (mm). For Alvania R3 at 1000 RPM, 50mm bore: interval ≈ 200 hours.
Shell Alvania R3 Grease offers several performance benefits, including: shell alvania r3 grease datasheet extra quality
Highly recommended for bearings in electric motors where a Grade 3 consistency is required. shell alvania r3 grease datasheet extra quality
Used in components that require long-term, reliable lubrication without frequent re-greasing. shell alvania r3 grease datasheet extra quality
Ambient temperatures fall below -20°C (use Alvania R2 or a synthetic grease for cold starts) or if speeds exceed 10,000 rpm (lighter NLGI 1.5 or 2 required).
Its long-term stability makes it a "fit and forget" solution for various sealed bearing types.
