Predict Bearing Service Life
> ADVANCED L10H CALCULATION BASED ON ISO 281 STANDARDS.
Bearing life refers to the number of revolutions or operating hours a rolling bearing can achieve before fatigue occurs. The L10 basic rating life represents the point where 90% of bearings remain operational.
For high-performance applications, ZGBK provides this Professional Lnmh Calculator to adjust for reliability, temperature, and shock loads.
Calculation Parameters
NOTE: THE RESULT REPRESENTS A THEORETICAL VALUE UNDER IDEAL OPERATING CONDITIONS AND SHOULD BE USED AS A REFERENCE FOR DESIGN AND SELECTION.
Formula: Lnmh = a1ft(106/60n)(C/Pfw)p
Factors Affecting Longevity
Load Conditions
Actual loads include axial and radial forces. Heavy vibration reduces life exponentially.
Operating Speed
High RPM increases heat generation and stress cycles, requiring precision lubrication.
Lubrication Quality
Effective oil film prevents metal-to-metal contact, drastically improving L10h.
Contamination
Dust and moisture lead to abrasive wear and premature fatigue on raceways.
Alignment
Incorrect installation causes uneven stress distribution and rapid failure.
