The angular touch ball bearing can accept both radial and axial loads. It can work at higher speeds. The larger the touch angle is, the higher the axial load can be. The high precision and high speed bearings usually take a 15 degree touch angle. Under the force effect; the touch angle will increase. The single-row angular touch ball bearing can only accept the axial load in one direction; when receiving the radial load; it will lead to the additional axial force. And can only constrain the shaft or the shell in one direction. Axial displacement. If paired double device; make the outer ring of a pair of bearings opposite; that is, the wide end faces the wide end face; the narrow end faces the narrow end face. This prevents the additional axial force from being caused; and can be in both directions Constrain the shaft or housing within the axial clearance range.
The angular touch ball bearing can have a relative displacement on the horizontal axis due to the inner and outer ring raceways; therefore, it can accept the radial load and the axial load combined load (the single row angular touch ball bearing can only accept the unidirectional axial load; thus usually The pair of devices are often used. The raw materials of the cage are brass, synthetic resin, etc.; they are distinguished by bearing method and operating conditions.
The angular touch ball bearings are: 7000C type (âˆ=15Â°), 7000AC type (âˆ=25Â°) and 7000B (âˆ=40Â°). The type of bearing has the lock on the outer ring; usually the inner and outer rings Can not be separated; can accept the combined load of radial and axial and the axial load in one direction. The ability to accept the axial load can be determined by the touch angle; the touch angle is large; the ability to accept the axial load is high. Axial displacement of the shaft or casing in one direction.
