[Basic guidelines for filling quantity]
Under high temperature and high speed rotation conditions, it is recommended to fill 15-20% of the free space volume of the bearing. This is a general standard for suppressing heat generation and torque increase, and extending the life of the grease.
【Application of Bell Hammer Metal Grease】
Bell Hammer Metal Grease is a high-performance grease primarily composed of solid lubricating components, differing in nature from urea grease. However, since it shares similar mechanical constraints regarding filling volume, using 15–20% of the space volume as a guideline is reasonable.
【Additional Advice】
• Excessive filling may cause performance degradation or heat-related issues.
• At high rotational speeds, stirring resistance may cause temperature increases, potentially shortening the grease's lifespan.
【Conclusion】
For Bell Hammer Metal Grease, we recommend filling to approximately 15–20% of the space volume, then observing temperature and behavior after use and making adjustments as needed.
