Angular contact ball bearing 7030/p4

d:150mmD:225mmB:35mm W: 4.7kg basic dynamic load ratings: 119kN basic static load ratings: 132kNlimit speed:1900~2800r/minAngular contact ball bearings feature: 1. To face configure line towards the load bearing polymer bearing axis. Axial load carrying in both directions, although each is only by a bearing (or series bearing) load. Rigidity of this configuration is not back to back arrangement so high, is not suitable for the overturning moment. 2. To configure the bearings back to back line towards the load bearing axis divergence. Can carry axial load in both directions, although each time only by a bearing (or series bearing) load. Back to back configuration relative rigidity to withstand overturning moment.　　3. Series bearings can not be compared with group group bearing or bearing adjustment, usually in series, and back to back, or a combination of serial and face to face configuration.　　4. In the series configuration, bearing the load line is parallel. The average distribution of radial and axial loads on the bearings, but only in one direction axial load carrying. Therefore, a set of bearings in series configuration is usually relative to another can take the opposite direction to adjust the axial load bearing.
