Angular contact ball bearings

Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis

The most commonly used designs are:

single row angular contact ball bearings

double row angular contact ball bearings

four-point contact ball bearings

In addition to the bearings presented in this section, other angular contact ball bearings include:

Super-precision angular contact ball bearings

Double row cam rollers

Fixed section angular contact ball bearings

Hub bearing units

Product Description

This 3317A bearing is a metric double row angular contact bearing without filling slots, with a steel cage, and a normal radial internal clearance. The bearing's dimensions are 85x180x73.

SKF Open Type Double Row Angular Contact Ball Bearings:

Correspond to the design of two single row angular contact ball bearings side by side but occupying less space. They can accommodate radial loads as well as axial loads acting in both directions. They provide a rigid bearing arrangement and accommodate tilting moments well.

Benefits: Compact, rigid, accommodates tilting, radial and axial loads

Brand / Quality: SKF - High Quality

Seals / Shields: None

Clearance: * Standard

SKF double row angular contact ball bearings correspond in design to two single row angular contact ball bearings arranged back-to-back, but take up less axial space. They can accommodate radial loads as well as axial loads in both directions. They provide stiff bearing arrangements and are able to accommodate tilting moments.

 The standard assortment of SKF double row angular contact ball bearings comprises bearings in the 32 A, 33 A and 33 D series. Bearings in the 52 and 53 series are no longer available from SKF and have been replaced with 32 and 33 series bearings. With the exception of size 3200, 32 and 33 series bearings are dimensionally interchangeable with bearings in the 52 and 53 series. Size 3200 has a width of 14 mm instead of 14.3 mm.

SKF BA1B 307788 bearing leader bearing in Reunion are widely used in industrial drive, agriculture, compressors, motors and generators, construction, industrial fan, industrial transmission and other fields. SKF BA1B 307788 bearing leader bearing in Reunion can ensure high quality for more than 80% raw material of SKF BA1B 307788 bearing leader bearing in Reunion provided by the steel plant.

Discription of Double Row Angular Contact Ball Bearings:

ngular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, and dentistry equipment, the centrifugal forces generated by the balls changes the contact angle at the inner and outer race.

angular contact ball bearing, is made of Chrome Steel. which have a contact angle so that they can sustain significant axial loads in one direction together with radial loads.

The features of  angular contact bearing is that it can bear both radial load axial load, the axial load capacity depends on how big the contact angle is, the bigger angle, the bigger capacity.

angular contact ball bearing  is mainly applied on high speed, high precision and little axial load occasions, such as airplane engine main shaft, machine tool main shaft and main shafts of other high speed precision machine. It can also be applied on high frequency motor, steam turbine, oil pump, air compressor and printing machine etc. It is one of the bearings most widely used in machinery industry.

-  Back-to-bacd arrangement (DB)

- Face to face arrangement (DF)

- Tandem arrangement (DT)

- Stamping steel cage (J)

- Stamping brass cage (Y)

- Nylon cage (TVP)

- High hardness fiber holder (TPA)

- One brass cage (MP)

 

Bearing feature:

1. With unidirectional and bidirectional two types

2. Use option in the ring, can permit of installation error.

3. High grade ball - high speed rotates the quiet and smooth

4. High Quality Steel - Ultra clean steel to extend bearing life by up to 80%.

5. The height of the grease technology - N-S-Klubricant technology can make the grease live longer and improve the performance of the bearing

6. In order to permit of installation error, whether one-way or two-way, can choose spherical self-aligning spherical seat cushion type or take ball seat ring type.
