According to related standard, the vibration noise (dB) of bearigs for their vibration under acceleration are divided into four groups:Z1,Z2,Z3and Z4. Also they can be divided into four groups in according to vibration speed (u m/s):V1,V2,V3 and V14.
Normlly, common bearings sre delivered with Z1 group vibration value if no special requirement from customers while the bearings for export will be delivered with vibration Z2 group specification. However, please note your special requirement on vibratoin inyour order.
Single bearing vibration noise under acceleration (dB) specification is shown on table
Single bearing vibration speed (u m/s) specification is shown on table.
