Several factors influence the quantity of grease that would go into a bearing at the selected interval. Critical factors include:
- Design of the bearing (plain, roller, ball or spherical roller).
- Type of shield used in the bearing.
- Size and speed from which to calculate dN values.
- Viscosity of the lubricant in the grease.
If you look closely at the manufacturer’s guidelines, you should see both general and specific directions for relubrication, including frequency and quantity for a given speed and load. The original equipment manufacturer (OEM) parameters are typically the best starting point for relubrication practices.
