Angular contact ball bearing
Angular ball bearings are also called angular contact radial thrust ball bearings. This type of bearing is particularly suitable for carrying combined loads (radial and axial load) as well as pure axial loads and can be operated at relatively high speeds. The axial load carrying capacity of angular contact ball bearings changes along with dimensions of contact angle. The larger the contact angle, the better the axial load carrying capacity is. The contact angle α is defined as the angle between the line joining the contact points of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.

Product Description of Angular contact ball bearing
- High load-bearing capacity
The lower shoulder allows a large number of balls to be packed into the bearing, giving it a relatively high load carrying capacity. - Good running characteristics
Fast acceleration and deceleration can be achieved. - Easy mounting of universal matched bearings
- No need to adjust the correct internal clearance or preload
- Angular contact ball bearings are designed to meet the increasingly demanding requirements of original equipment manufacturers.
- These bearings have contact angles so that they can carry significant axial and radial loads in one direction.
- offers one of the most comprehensive ranges of angular contact ball bearings.
Single row angular contact ball bearings are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet metal or brass cages.
The raceways of the inner and outer rings are offset from each other along the bearing axis. The bearings are available in open and sealed designs. They have very limited angular adjustment capabilities.
Double row angular contact ball bearings can withstand axial loads in both directions and high radial loads.
They are particularly suitable for bearing configurations where rigid axial guidance is required.
- Angular contact ball bearing
Pre-lubricated bearings have integral seals or shields and are filled with long-life grease. - In many applications, these bearings can be used without additional seals, enclosures or protectors.
- Shielded ball bearings are protected on one or both sides by a metal shield fixed to the outer ring.
- This tight clearance shield retains lubricant and helps prevent the entry of large foreign objects.
- Sealed ball bearings use steel-reinforced rubber seals that are firmly fixed in the grooves of the outer ring. Contact with the inner ring always provides a reliable seal.
- We also offer a variety of contact, light contact and non-contact seals to help protect you while balancing speed and torque requirements
- High quality steel – Ultra clean steel extends bearing life by up to 80%.
- Advanced grease technology – lubricants extend the life and performance of grease.
- High-grade balls – quiet and smooth operation even at high speeds
- Super-finished raceways – specially ground to minimize noise and improve lubricant distribution and life.
- Contact angles – available in 15, 25, 30 and 40 degree angles.
Cages – available in a range of polyamide, steel and brass cage assemblies.
Application of Angular contact ball bearing
- Angular contact bearings are ideal for use in gearboxes, pumps, motors and clutches or other high-speed applications. They are commonly used in material handling, machine tools, steel mills and the wind energy industry.
- Because angular contact ball bearings are available in hundreds of different sizes and because these bearings come in two types, they are used in a wide range of industries and equipment.
- Angular contact ball bearings for agricultural applications
- The needs of the agricultural industry are heavy machinery and equipment. Angular contact ball bearings are known for their high performance and high axial and radial load capacity, making them an ideal solution for agricultural machinery.

FAQ
Due to their internal design, ball bearings cannot usually be disassembled down to the component level; therefore, they cannot usually be refurbished.
Solid base shells are manufactured without cavities and fillers; they are stronger than hollow bases, and there are no traps for bacteria and fungi to grow. In the thermoplastic shell, the sturdy base will not break under steam or high-pressure washing. The hollow base saves material and weight to reduce costs. Some people use epoxy resin to backfill the hollow base to eliminate the trap of bacteria breeding, but this will not increase the strength, will cause the installation surface to be uneven, and water will seep between the shell and the filling material, causing cracking.
Use particularly thermally stable bearing rings, larger internal clearance (C4), specially selected lubricants that will not decompose at high temperatures, and zinc anodized flinger. There are two basic versions of our high temperature bearings. The suffix “C4HR5” represents the bearing that can withstand 400°F, and the suffix “C4HR23” represents the bearing that can withstand 450°F.
For critical applications such as pulp and paper processing, printing and packaging, material tearing can cause expensive downtime due to excessive torque and vibration.
The two biggest factors affecting the starting and running torque of the bearing are the seal design and lubricant selection. The shaft and bearing seat fit, component accuracy and surface finish, and retainer design also have some influence.
In higher speed applications, non-contact sealing devices are usually required to minimize operating torque and heat generation, so oil baffle rings and secondary sealing devices are usually required. Flowing oil lubrication systems are usually the best solution.
After proper installation, most seated bearings only need to be relubricated regularly with a small amount of grease and checked to ensure that they operate at low temperatures, quietness, and sufficient accuracy.
This depends on many factors, such as the application’s load conditions, operating speed, duty cycle, temperature, and operating environment. The technical information section of this website provides some basic information. Our engineers can help you determine more specific theoretical life calculations.
When noise and/or operating temperature increase or operating accuracy decreases, bearings should be replaced.
Lubricant of choice
Lubrication joint type or location
Sealing materials and design options
Dimensions, suitable for housing or insert
Fixing screw options
Paint the shell in any color
Too little or too much lubricant
Incorrect lubricant type
Poor bearing installation
Improper internal clearance
Excessive load and/or speed
Extreme temperature
Pollution
Movement between mounting surfaces
The noise emitted by the bearing may be caused by a combination of one or more factors, such as insufficient working clearance, excessive working clearance, changes in working clearance due to temperature, damage to the contact area, contamination, inappropriate lubricants or The raceway is damaged.
Lubricants have five basic functions for bearings:
Reduce friction
Reduce wear
Reduce temperature rise
Minimize corrosion
Seal contaminants
We do not recommend mixing grease. Mixing incompatible greases will cause the mixture to harden, preventing it from releasing any oil. Mixing incompatible greases can also soften the mixture, which releases all the oil. In either case, the mixture will not be able to properly lubricate the bearing. We strongly recommend using the same type of grease originally provided with the bearing.
