What is the purpose of angular contact ball insulated bearings of insulated rolling bearings

wallpapers Industry 2020-10-26
Angular contact ball insulated bearing rings have contact angles with the ball. The standard contact angles are 15°, 30° and 40°. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the more conducive to high-speed rotation.
Single row insulated bearings can bear radial load and unidirectional axial load, DB combination, DF combination and double row bearings can bear radial load and bidirectional axial load. The DT combination is suitable for occasions where the unidirectional axial load is large and the rated load of a single bearing is insufficient. High-speed ACH type bearings have small ball diameters and many balls, and are mostly used in machine tool spindles.
Angular contact ball bearings are suitable for high-speed and high-precision rotating structure with two single row angular contact ball bearings combined on the back. Shared inner ring and outer ring, can bear radial load and bidirectional axial load.
The non-filled groove bearing also has a sealed type. The main applicable cages are: steel stamping cage (bowl shape...single row; S shape, crown shape...double row) copper alloy or phenolic resin cutting cage, synthetic resin forming cage
The main purpose:
Single row: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, front wheel of small car, differential pinion shaft
Double row: oil pump, roots blower, air compressor
Various transmissions, fuel injection pumps, printing machinery.
Four-point contact ball bearings can withstand radial loads and bidirectional axial loads. A single bearing can replace angular contact ball bearings with front or back combinations. It is suitable for bearing pure axial load or synthetic load with larger axial load component. This type of bearing can form a contact angle (α) when bearing axial load in any direction, so the ring and the ball are always on any contact line. Mainly applicable cage: copper alloy cut cage.
Main applications: aircraft jet engines, gas turbines, etc.
