Product details
Model Number: 71918 Brand Name: ZYS Key Specifications/Special Features: ZYS singlerow angular contact ball bearings can bear radial load and one direction axial load.And radial loads produce axial forces in these bearings.Therefore, the single-row angular contact ball bearings are often used with other bearings which can withstand axial load in the opposite direction.That is, angular contact ball bearings are commonly used in pair, or in setswith three, four and even five bearings.Angular contact ball bearings have higher limited speed,1. Contact anglesZYS precision angular contact ball bearings with15°(C) and 25° (AC) contact angular. As for the angular contact ball bearings, the bigger of the contact angle is, the greater the axial load capacity is, the bearing with 15° contact angle is used when the high speed and light axial load are needed, and the 25° contact angle bearing should be adopted on the contrary. The paired use can bear both axial load and radial load or synthetic2. Four dimension series
The precisionangular contact ball bearings for spindles have four dimension series, 718, 719, 70 and 72. With the same inner diameter, the outer diameter and the width of 718, 719, 70 and 72 increase in turn
3. Application:
Machine tool spindle
Robot technology
High-frequency motor
Gas turbine
Centrifuge
Small-size automobile front wheels
Differential pinion shaft
4. Advantages:
The inner ring , outer ring and rolling element are made in high carbon chromium bearing steel, the chamfer arc radius of rings is reasonable, which is not only convenient to install, but also guaranteed to improve the installation precision and reduce the risk of the related parts being bumped;
The speed performance is outstanding
Unique heat treatment process allows products to achieve the best dimensional stability and rigidity, so as to reduce wear and tear;
Multiple pre-load levels can help to meet different requirements for speed and system stiffness, which is more reasonable to select and use the levels.
5. The principles of selectingprecision bearings
ZYS has developed and produced various kinds and structures of high-speed precision bearings, each of which has special working conditions. Selecting different types and structures should depend on specific working conditions. When choosing bearings, the following properties should be taken into consideration.
6. Application
For the high-precision bearings, 18,19, (1) 0 dimensional seriesin particular, the bearing ring thickness is thin, so the fitting condition, when the bearing is assembled to spindle and housing, has a significant impact on the running accuracy, internal clearance or preloadof the bearing. Therefore, not only the bearing
