Results are engineering estimates based on industry-standard bearing lubrication formulas (regrease volume Gₓ = D × B × K, where K = 0.005 for side ports or 0.002 for center-ring ports; NLGI frequency methodology with environmental correction factors). Actual intervals vary with grease type, bearing manufacturer recommendations, and operating conditions. Use condition-based monitoring such as ultrasound or grease analysis to refine intervals in service.
