SKF Self-aligning ball bearings:
The SKF self-aligning ball bearing is a bearing equipped with spherical balls between the inner ring of two raceways and the outer ring with spherical raceways.
There are two rows of steel balls, the inner ring has two raceways, the outer ring raceway is an inner spherical type, and the center of curvature of the outer ring raceway surface is consistent with the bearing center, so it has self-aligning performance.Need SKF Self-aligning ball bearings SKF 2209 EKTN9
When the shaft and casing deflect, it can be adjusted automatically without increasing the bearing burden. It can automatically compensate for the coaxiality error caused by the deflection of the shaft and the deformation of the housing. It is suitable for the parts of the bearing seat and cannot guarantee the coaxiality.
This kind of bearing mainly bears radial load. While bearing radial load, it can also bear a small amount of axial load. It is usually not used to bear pure axial load. For example, if a pure axial load is received, only one row of steel balls is stressed. The radial load capacity is large, suitable for heavy load and impact load.
The inner diameter of the inner ring is a tapered bore bearing, which can be installed directly. Or use adapter sleeve and dismounting cylinder to install on the cylindrical shaft. The cage uses steel stamping cage, polyamide forming cage and copper alloy car cage.
Application fields:
Self-aligning ball bearings are suitable for industries such as heavy and shock loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, cement, sugar extraction and general machinery.
SKF Spherical roller bearing:
SKF Spherical roller bearings are bearings with drum rollers assembled between an inner ring with two raceways and an outer ring with spherical raceways.
With two rows of rollers, it is mainly used to bear radial loads and can also withstand axial loads in either direction. The radial load capacity is high, especially suitable for work under heavy load or vibration load, but can not bear pure axial load; the outer ring raceway of this type of bearing is spherical, so its self-aligning performance is good and can compensate for coaxiality errors.Buy SKF Spherical roller bearing SKF 22214E/C3
