Bearing Grease Quantity Calculator
Estimate a relubrication top-up quantity for grease supplied from the side of a bearing, using its outside diameter and width. Results are an initial selection aid and must be checked against manufacturer information.
Bearing Grease Quantity
Relubrication top-up estimate for grease supplied from the side of a bearing: G = 0.005 × D × B (grams).
Calculation assumptions
This estimates a replenishment quantity, not the initial bearing or housing fill. It applies to grease supplied from the side of a bearing; relubrication through the bearing rings requires different guidance. Confirm quantity, interval and suitability with the bearing or equipment manufacturer, allowing for bearing type, speed, temperature, contamination and grease escape paths. Do not apply this estimate to sealed-for-life bearings.
