Angular contact ball bearings and deep groove ball bearings are all representative needle roller bearings, which have a wide range of applications and can bear radial and two-way axial loads. They can be used for high-speed operation and require low noise and low vibration sites. Sealed roller bearings with carbon steel plate dust cover or silicone rubber sealing rings are filled with grease beforehand, and roller bearings with stop rings or punch dies on both sides are used. It is easy to locate accurately in the axial direction and beneficial to the installation in the shell. The specifications and models of large-load roller bearings are the same as those of standard roller bearings, but there is a filling groove inside and outside, which improves the number of balls and improves the smooth load.

The type and direction of load are different:

Deep groove ball bearings:

Deep groove ball bearings are a more common type of needle roller bearings. It is important to bear radial loads, but it can also bear radial loads and axial loads. The surface tension is zero when the work is only bearing radial load. When deep groove ball bearings have very large radial backlash, they have the characteristics of angular contact roller bearings and can bear very large axial loads. The friction resistance of deep groove ball bearings is not large, and the limit transmission ratio is also very high.

Angular contact ball bearings:

Between the ring and the ball is the surface tension, the standard contact Angle of 15/25 and 40 degrees three, the higher the Angle of contact under the premise. The larger the capacity of axial load is in the work, the column roller bearing can bear radial load and unilateral axial load, DB composition, DF composition and angular contact ball bearing of self-aligning roller bearing can bear radial load and two-way axial load, DT constitute the field where single axial load is very large and independent roller bearing stable load is insufficient, ACH type roller bearing is quickly used. The ball diameter is small, the number of balls is large, most of them are used for machine tool spindle. In general, angular contact ball bearings can be rapidly and precisely machined for rotating fields.

The structure industry is different:

1, deep groove ball bearings on both sides of the cross-sectional double shoulder, and angular contact ball bearings are generally single shoulder;

2. The refraction rate of cross section on both sides of deep groove ball bearings is different from that of angular contact ball, and the back one is generally higher than the front one;

3. The position of the internal cross section of angular contact ball bearings in each part of the deep groove ball bearing is different. For other parts, the actual value is considered in the design of angular contact ball bearings, which is related to the degree of contact Angle;

In terms of scope of application:

1. The scope of application of the two is different. Deep groove ball bearings are suitable for bearing radial force, relatively small axial force, axial and radial collaboration load and torsional load. Angular contact ball bearings can bear single radial load and very large axial load (which varies with different contact angles), and double pairing (which varies with different matching methods) can bear bi-directional axial load and torsional pitch load.

2. The ultimate transmission ratio of deep groove ball bearings is different from that of angular contact ball bearings. Under the same specification and model environment, the ultimate transmission ratio of angular contact ball bearings will be higher than that of deep groove ball bearings.
