Bearings are one of the most important parts in mechanical equipment. It mainly supports the mechanical rotating body and reduces the friction coefficient of the mechanical load during the transmission of the equipment. There are many types of bearings, and different types of bearings can be selected according to different uses.

Deep Groove Ball Bearings

The most representative one is the rolling bearing, which has a wide range of uses, can withstand radial load and bidirectional axial load, and is suitable for occasions with high-speed rotation and noise and vibration requirements. The sealed type bearing with steel plate dust cover or rubber sealing ring has been pre-filled with grease, and the outer ring has a stop ring or flange, which is convenient for axial positioning and assembly in the shell. Maximum load type The size of the bearing is the same as that of the standard bearing, but there is a filling groove in the inner and outer rings, which increases the number of rolling balls and greatly improves the rated load.

Angular contact ball bearings

There are contact angles between the ring and the ball of angular contact bearings. The standard contact angles are 15 degrees, 25 degrees and 40 degrees. The larger the contact angle, the greater the axial load capacity; the smaller the contact angle, the more conducive to high speed. Rotating, single row bearings can bear radial load and unidirectional axial load, DB combination, DF combination and double row angular contact ball bearings can bear radial load and bidirectional axial load, DT combination is suitable for unidirectional axial load comparison Larger, insufficient rated load of a single bearing, small ball diameter and a large number of balls, are mostly used for machine tool spindles.

In general, angular contact ball bearings are suitable for high-speed, high-precision rotating equipment.

Structure difference

Deep groove ball bearings and angular contact ball bearings with the same inner and outer diameter and width dimensions have the same inner ring size and structure, but the outer ring size and structure are different:

  1. Deep groove ball bearings have double shoulders on both sides of the outer ring channel, while most angular contact ball bearings are single shoulders;
  2. The curvature of the outer ring raceway of deep groove ball bearings is different from that of angular contact ball bearings, the latter is generally greater than the former;
  3. Deep groove ball bearing outer ring track position is also different from an angular contact ball bearing. It is not the center position. The specific value is taken into account in the design of angular contact ball bearing and is related to the degree of contact angle.

Use difference

  1. According to the different attributes of the two, there are differences in the use of applications. Deep groove ball bearings are suitable for bearing radial forces, small axial forces, combined axial and radial loads and moment loads; angular contact ball bearings can bear a single radial load and larger axial loads (depending on the contact angle There are differences), double pairing (different with different pairing methods) can withstand two-way axial load and moment load.
  2. Due to the different properties of the two, the limiting speed is different. The limiting speed of angular contact ball bearings of the same size is higher than that of deep groove ball bearings.
