Bearing show: Precision Deep Groove Ball Bearings(EMQ Bearings) 698ZZ 8*19*6mm
Deep groove ball bearing is the most representative rolling bearing,it can suffer from both axial and bidirectional radial load. It can be used in these occasions with the demand of high rotation,low noise, and low oscillation. Bearing with seal together with steel cover of rubber seal usually filled with lubricant inadvance ,the outside ring with stopping circle or flange,these will not only be easier for axial orientation, but also good for the installing of outside shell.The size of maximum loading bearing is just the same as standard bearing, while with back fill trough in the inside and outside, which can add the balls,and improve the maximum load at the same time.
Corresponding designation equivalent Gcr15
Ⅲ. Vibration and Noise
According to ralated standard, the vibration noise(dB) of "DAW" bearing for their vibration under acceleration
and divided into four groups:Z1,Z2,Z3,Z4.
Also the bearing can be divided into four groups in according to vibration speed" V1,V2,V3,V4.

Based on reliable quality , Daiwa has got great achievement in the field of high rotating speed, and cooperated with several aeromodelling motor companies to develop good ball bearing with high speed,low noise,long life features. Advantages in the manufacturing process gradually formed and started to take a fixed market share. Shared a very big market in excess of 70% for miniature ball bearing domestically. Especially in aeromodelling market ,we are taking 80% market share .
