Precision Angular Contact Ball Bearings

Series:718 series, 719 series 
The bearing Can withstand radial load and axial load at the same time. It can work at a higher speed. The contact angle is greater,the axial load capacity is larger,but the bearing limiting speed is lower. After purchasing,the bearing should be adjusted at the time of installation, so that the operating clearance or preload to achieve the required range. If the user makes a request. CHG can also be supplied in groups.
