Deep groove ball bearings are typical rolling bearings with a wide range of applications that can withstand radial and bi-directional axial loads and are suitable for high speed rotation and applications requiring low noise and vibration.
Deep groove ball bearings are simple in structure and easy to use. Mainly used to bear radial load. Can be used to bear pure axial load, but also can bear the combined radial and axial load.
Sealed type bearing with steel plate dust cover or rubber seal, pre-filled with grease, outer ring bearing with stop ring or flange, both easy to axial positioning and easy to install on the shell, larger size bearing with the same standard bearing, but the inner and outer ring has a fixed groove, increasing the number of ball loading and increasing the rated load.
Angular contact ball bearing: contact angle between the collar and the ball, the standard contact angle of 15/25 to 40 degrees, the contact angle is large when the axial load capacity, the contact angle is small conducive to high-speed rotation.
Single row bearing can bear radial load and one-way axial load, DB, DF and double row angular contact ball bearing can bear radial load and two-way axial load, DT group is suitable for one-way axial load and single bearing rated load is not enough, high-speed use ACH type bearing, ball diameter is small, ball number is large, mainly used for machine tool spindle.
In a word, angular contact ball bearings are suitable for high speed and high precision rotating occasions. Inside and outside diameter is the same, the width of the same deep groove ball bearings and angular contact ball bearings, the inner ring size, structure is the same, while the outer ring size, structure are different.
1, deep groove ball bearing outer ring groove both sides of the double shoulder, angular contact ball bearings generally only a shoulder.
2, deep groove ball bearing outer ring groove curvature and angular contact ball bearings are different, often larger than angular contact ball bearings.
3, deep groove ball bearing outer ring groove position and angular contact ball bearing is different, non-center position, the specific value by the design of the consideration, and the size of the contact angle.
