SNR 71926HVUJ74A High precision angular contact ball bearings
The Limiting Speed depends on the SNR 71926HVUJ74A type, dimensions, lubricating method, load, etc. The Limiting Speed of a Longer Life Precision Bearings is limited by the circumferential speed of the contact sections of the seal and raceway ring. When using a Longer Life Precision Bearings at 75% or more of its Limiting Speed, select the correct required grease type and amount or the correct lubrication oil and method.
