Understanding NLGI Grades for Grease Selection

NLGI describes grease consistency, not overall quality, and affects pumpability and retention.

• Why This Topic Matters - Understanding NLGI Grades for Grease Selection affects bearing life, grease consumption, downtime, and maintenance cost. Good selection reduces trial-and-error in the field.
• Grease Selection Checklist - Confirm temperature, speed, load, water, dust, application method, relubrication interval, compatibility, and packaging before ordering.
• What to Send for a Recommendation - Send equipment type, speed, load, operating temperature, water or dust exposure, current grease, preferred NLGI grade, and packaging requirement.
