Have questions about bearings? You’re in the right place.
Find quick answers to common questions about selection, installation, maintenance, and more.
What causes abnormal noise or vibration during operation?
A: Common causes include poor lubrication, contamination, improper installation, incorrect clearance, or component damage (e.g., pitting, cage breakage). Inspect immediately and address root causes.
How much grease should I add? Is more better?
A: No—over-greasing causes overheating. Fill 1/3 to 1/2 of the free space inside the bearing. Sealed bearings come pre-lubricated and usually need no extra grease.
What are key tips for installing bearings correctly?
A: Keep everything clean, use proper fits (avoid hammering), heat ≤120°C if needed, and ensure shaft/housing alignment. Incorrect mounting is a leading cause of early failure.
What does “basic rating life” mean? How long will my bearing last?
A: Basic rating life (L₁₀) is the life 90% of identical bearings achieve under standard conditions. Actual life depends on lubrication, contamination, installation, and temperature—often varying significantly from L₁₀.
