Feature of Angular contact ball bearings:
When the single-row angular contact ball bearing is carrying the radial load, they will be a component of force in the axial direction. Therefore it is suggested that two of there bearings be applied in back-to-back or face-to-face arrangements. Single row bearings can carry radial load and axial load in one direction. Double-row angular contact ball bearings have two designs of one outer ring and two inner rings and one outer ring and one inner ring. For the design with one outer ring and two inner rings, the axial clearance is easy to control during machining.
Applications:
These bearings are mainly applied in the machine tool spindles, high-frequency motors, gas turbines, oil pumps, air compressors, printing machines and other installations.
Ball Bearing - Spindle Bearings
Spindle ball bearings are single-row large ball bearings characterized by their particular design engineered with either a 15° or a 25° angular contact. They contain raceways in both the inner and outer rings which can be displaced in relation to the bearing axis and in relation to each other. These rings are assembled with a stationary cage, and the balls cannot be dismantled from the ball bearing housing.
Spindle ball bearings are designed to provide the utmost support for a number of different types of loads making them popular mining bearings. The mechanism's loading capacity proportionally increases with the augmentation of the contact angle. Due to the device's eminent and relentless accuracy, these ball bearings are often utilized when there is a need for utmost precision, high bearing capacity, high-speed and an impeccable accuracy. As a result, they are primarily used as machine tool spindle bearings and mining bearings.
Engineering & Design
Spindle bearings are designed with a soaring level of radial and axial rigidity in order to accommodate to heavy loads and high speed environments. The axial load is supported in only one of its sides, and is adjusted against a second spindle ball bearing of the same type.
The rings of high speed spindle bearings are typically made from corrosion-resistant steel, while the balls are made from either steel or ceramic. In order to decrease the mechanism's friction and increase the speed, the device is usually supported by a solid plastic (usually phenolic resin) window cage, but different materials are available and may be chosen to accommodate specific room temperatures. Spindle ball bearings are often finished with an external grease, oil or air lubricating coating.
In order to comply by ISO regulations, spindle bearings must abide by tolerance restrictions in regard to their accuracy and dimensions. While these control the shaft's installation onto the bearing houses and the dimensions of the apparatus, the regulations create universal standards which yield utmost simplicity in dissembling and replacing pieces of large ball bearings worldwide.
Models
There are two primary kinds of spindle bearings:
Open Spindle Bearings: These types of spindle bearings contain large balls inside the bearing housing in order to maximize its performance capacity. The external ring in these large ball bearings usually has only one shoulder.
Closed Spindle Bearing: This model has the same external dimensions as open large ball bearings, but is often packed with small balls, reducing the capacity yet increasing the axial rigidity and speed.
