Difference Between Deep Groove Ball Bearing and Angular Contact Ball Bearing

- May 05, 2021 -

What is angular contact ball bearings

There are raceways on the inner and outer rings of angular contact ball bearings, and the inner and outer rings can be mutually displaced along the axial direction of the bearing. This kind of bearing is especially suitable for bearing compound load, namely, radial and axial simultaneous action of the negative load. The axial load bearing capacity of angular contact ball bearings increases with the increase of contact Angle α. The contact Angle is the Angle between the contact point line of the ball and the raceway in the radial plane and the vertical line of the bearing axis.

Characteristics of angular contact ball bearings

General purpose assembly bearings are specially engineered so that when the bearings are mounted close to each other, any combination can achieve a given internal clearance or preload, as well as an average load distribution, without the use of gaskets or similar devices.

Application of angular contact ball bearings

Single row angular contact ball bearings: machine tool spindle, high frequency motor, combustion steam turbine, centrifugal separator, small car front wheel, differential pinion shaft.

Double row angular contact ball bearings: oil pump, Roots blower, air compressor, all kinds of transmission, fuel injection pump, printing machinery.

Difference Between Deep Groove Ball Bearing and Angular Contact Ball Bearing

Difference between deep groove ball bearing and angular contact ball bearing

Deep groove ball bearing is a representative of the rolling bearing, widely used can bear radial load and axial load, two-way is suitable for high speed rotation and requiring low noise, low vibration, steel plate with dust cover or rubber sealing ring seal type prefill the grease inside the bearing, to go stop ring or flange bearing, axial positioning, easy and convenient for the installation.The size of the maximum load bearing is the same as that of the standard bearing, but the inner and outer ring is filled with another groove, which increases the number of balls and improves the rated load.

Angular contact ball bearing of uranium with contact Angle between the ring and ball, standard contact Angle is 15/25 and three kinds of 40 degrees, the larger the contact Angle is the ability to load, the greater the contact Angle is smaller, the more conducive to high-speed rotation, single row bearing can bear radial load and axial load one-way, D combination, combination of DF, and double row angular contact ball bearings can withstand radial load and axial load, two-way The combination is suitable for the occasion where the unidirectional axial load is large and the rated load of each bearing is insufficient. The ball diameter is small and the number of balls is many. It is mostly used for the spindle of machine tool. In general, angular contact ball bearings are suitable for high-speed and high-precision rotation occasions.

For deep groove ball bearings and angular contact ball bearings with the same inner and outer diameter and width, the size and structure of the inner ring are different, while that of the outer ring is different.

1. The deep groove ball bearing is double-shouldered on both sides of the outer groove, while the angular contact ball bearing is generally single-shouldered.

2. The raceway curvature of the outer ring of deep groove ball bearings is different from that of angular etched balls, and the latter is often different from the former.

3. The raceway position of the outer ring of deep groove ball bearing is different from that of angular contact ball bearing. The specific value of the non-central position is considered in the design of angular contact ball bearing and is related to the degree of contact Angle.

In terms of use:

1. Two different purposes, deep groove ball bearing is suitable for small axial force and radial force, under, axial-radial joint load and torque load, and the single angular contact ball bearings can bear radial load, large axial load  according to the contact Angle different, twin pairs (varies with the pairing) can carry double words of axial load and torque load.

2. Different limit speed, the limit speed of angular catch ball bearings of the same size is higher than that of deep groove ball bearings.
