Angular contact ball bearings

Angular contact ball bearings support both radial and axial loads through asymmetric races that house the bearing’s spherical rolling elements, also called bearing balls, on an angle. The deeper the angle between the bearing and its axis, the greater the axial load the bearing can carry. Because the axial load is proportionate to the radial load, a greater axial load capacity means less radial load capacity. Angular contact ball bearings come in single- and double-row configurations depending on the direction of loads they carry. Single-row angular contact ball bearings only support axial loads in one direction, while double-row angular contact ball bearings support axial loads in both directions. In addition, we also produce miniature angular contact ball bearings. 

Manufactured to the same close tolerances as the radial type, but designed with contact angles of 15, 30, and 40 deg to accommodate greater thrust loads.

Applications

 Angular contact ball bearings are engineered for use in high-speed, high precision applications for:

 * Dental and medical equipment

 * Chemical

 * General industry

 * Utilities

 * Turbocharger 

A common choice, at higher precision levels, for applications such as machine tool spindles where both accuracy and high thrust loads are present. They are typically mounted in pairs, also called duplex bearings, providing thrust capacity in either direction and good rigidity for applications where shaft movement is critical.


BestQuality single row angular contact ball bearings Factory
single row angular contact ball bearings can accommodate axial loads in one direction only, and should always be adjusted against another bearing which accommodates the opposed thrust load.  Their bearing rings have an upper and a lower shoulder and are non-separable.Spindle bearings are a special design of the single row angular contact ball bearings; they were developed primarily for high-speed work spindles of machine tools. The spindle bearings differ from the angular contact ball bearings by the contact angle, the degree of accuracy, and the type of cage. Single row angular contact ball bearings, which are intended for mounting in pairs (in sets) directly adjacent to each other, are manufactured in the so-called universal design.these bearings can be used in pairs in any arrangement without shims. Depending on the design selected, the mounted bearing pair has the required axial clearance, freedom from clearance or preload. This gives easier design of the bearing arrangement and mounting of the bearings.Wuxi LOTTON Bearing Manufacturing Co., Ltd.

Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported (Load ratio). The bearings are separable, comprise solid outer rings, split inner rings and ball and cage assemblies with brass or polyamide cages. The two-piece inner rings enable a large complement of balls to be accommodated. The inner ring halves are matched to the particular bearing and must not be interchanged with those of other bearings of the same size. The outer ring with the ball and cage assembly can be mounted separately from the two inner ring halves.Four-point contact bearings are single-row angular contact ball bearings and therefore require significantly less space in an axial direction than double-row designs.In conclusion, these advantages improve the overall cost-efficiency of the bearing position significantly and thus bring about a sustainable increase in the efficiency of the machine and equipment.Wuxi LOTTON Bearing Manufacturing Co., Ltd.

Double row angular contact ball bearing
Double row angular contact ball bearingsThe design of the double row angular contact ball bearing corresponds to two single row angular contact ball bearings arranged back to back. The bearing is capable of carrying high radial loads and thrust loads in both direction. It is particularly suitable for applications calling for high axial rigidity.Double Row Angular Contact ball bearings may offer some economic benefits as well as handling and mounting benefits versus pairs of Single Row Angular Contact ball bearings; however, they may offer less design flexibility and performance in some cases.Design Attributes * Specific geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads. * Expanded options include special lubricants, cage materials, preloads and coatings for additional corrosion resistance. Double Row Angular Contact ball bearings are available in two numerical series:?5200 Series – Lighter load, higher speed, more/smaller balls per bore diameter.?5300 Series – Heavier load, slower speed, fewer/larger balls per bore diameter.If you need help in selecting the best products for your particular application, please remember that design engineering and application assistance are available from LOTTON as part of our value-added services designed to make your job easier.
