Too long between lubrications causes grease starvation and premature failure; too short causes over-greasing, which also damages bearings.</p> <h2 id="formula-iso-281--skf-method">Formula (ISO 281 / SKF Method)</h2> <p><strong>tf (hours) = (14 × 10⁶ / (n × √d)) − K</strong></p> <p>Where:</p> <ul> <li><strong>n</strong> = rotational speed (rpm)</li> <li><strong>d</strong> = bearing bore diameter (mm)</li> <li><strong>K</strong> = speed factor correction (0 for n ≤ ndm/2; higher values for faster bearings)</li> </ul> <p>Simplified for dairy plant bearings at moderate speed:</p>
