Relubrication Guide

Determining the correct Klüber relubrication interval is essential for maximizing bearing life and minimizing maintenance costs. The following guidelines apply to KLÜBER Barrierta L:

Recommended Relubrication Intervals

For food-grade high-temperature perfluorinated grease with NLGI 2 (typical; varies by grade), under normal operating conditions (moderate speed, <70°C, clean environment), a baseline relubrication interval of 6-12 months is recommended. This is a starting guideline — actual intervals should be adjusted based on:

• Operating temperature — grease life halves for every 15°C increase above 70°C
• Speed factor (n×dm) — higher speeds require more frequent relubrication with smaller quantities
• Environment — wet, dusty, or high-vibration environments shorten relubrication intervals by 30-50%

Relubrication Quantity

Use the general formula: G = 0.005 × D × B, where G = grease quantity in grams, D = bearing OD (mm), B = bearing width (mm). For high-speed applications, reduce the calculated quantity by 30-50%. Fill 30-50% of bearing free space for standard applications.

Condition-Based Monitoring

For critical equipment, use ultrasonic grease monitoring or vibration analysis to optimize relubrication intervals. Contact KOEED for a KLÜBER product recommendation tailored to your specific operating conditions.
