QFeatures of MISUMI Economy series Bearings
Economy series New 1Why are all MISUMI Economy series Bearings tested for noise and vibration? And why do we insist on achieving "Z1" level?
Specs
Bearings Through the test of Bearing noise and vibration, we can find out whether the Bearing is defective. Bearing
vibration is divided into four levels: Z0, Z1, Z2, Z3 and Z4 (Higher level, Lower noise and vibration)
