Precision Angular Contact Ball Bearings
Series: 718 series & 719 series
Precision Angular Contact Ball Bearings
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.
The spindle bearing produced by our company is single row angular contact ball bearing with high-precision , mainly used in lathe spindles , robot arm , measuring instrument etc . This kind bearing was designed specially for high technology , have the following characteristics :
1. High Precision
2. High-speed Performance
3. High Rigidity
4. Low Vibration
5. Low Temperature rise
