2, angular contact ball bearings are characterized by both radial and axial loads, high speed, the contact angle, the higher the axial load carrying capacity. Single row bearings can withstand axial load in one direction rail slider brands in the radial load, will cause additional axial force. And the only limit the axial displacement in one direction of shaft or housing. If paired mounting rail slider, a pair of bearing outer ring relative to that wide side face of wide and narrow side facing the narrow end. This can avoid additional axial force circular rail slider, and the shaft or housing to limit the axial clearance range in both directions. Angular contact ball bearing structure up to 70 kinds of variations. 2.1 nominal contact angle of 15 °, 25 °, 40 ° are three, the higher the contact angle the greater the axial load carrying capacity. High-precision and high-speed bearings usually take the contact angle of 15 °, the axial force, the contact angle will increase. 2.2 is generally inner or outer ring interlocking mouth, inner and outer rings can not be separated. After the thermal expansion of the outer ring and the inner ring, rolling elements, cage module assembly. Ball count more than the deep groove ball bearings, ball bearings rated load maximum, rigid and smooth operation. 2.3 can take advantage of the outer ring to adjust the radial clearance mutual displacement. Often used in pairs, and applying a pre-load, in order to improve the bearing rigidity. High-speed precision angular contact ball bearing installation: High-speed precision angular contact ball bearings, mainly for high-speed rotating light load situations requiring precision bearings, high speed, low vibration and low temperature rise limited life. Often high-speed spindle bearing installed in pairs, the inner surface grinding machine spindle speed key component parts. The main technical indicators: 1. Bearing precision index: more than GB / 307.1-94 P4 level precision 2. High-speed performance: dmN value of 1.3 ~ 1.8x 106 / min 3. life (average):> 1500 h high-speed precision angular contact ball bearing life of a great relationship with the installation, you should note the following: 1. Bearing installation should be carried out in the clean, clean room, bearing should carefully matching, bearing spacer to go through the grind, in keeping inner ring spacer Under the premise of high-ring, the cage should be controlled in parallel 1um or less; 2. bearing should be cleaned before installation, cleaning the inner slope upward linear guide slider, feel should be flexible, no sense of stagnation, dried, in the specified amount of grease, oil mist lubrication should be placed in the case of a small amount of oil mist; 3. Bearing installation should use special tools, even by force, non-beat; 4. Bearings shall be stored in clean and ventilated, non-corrosive gases, relative humidity not more than 65%, long-term storage should be regularly rust.
