High Precision Self-aligning Ball Bearings Chrome steel GCr15 1200ATN
Self-aligning ball bearings are bearings equipped with round balls among the internal ring of two raceways and the outer ring of which the raceways are spherical.
The center of curvature of the outer ring raceway surface is consistent with the center of the bearing, and it has the same self-aligning function as the self-aligning Ball Bearing. When the shaft and housing are deflected, they can be adjusted automatically without increasing the bearing burden. Spherical roller bearings can withstand radial loads and axial loads in two directions. Large radial load capacity, suitable for heavy loads and shock loads. The inner diameter of the inner ring is a bearing with a tapered bore, which can be directly mounted. Or install it on the cylindrical shaft using an adapter sleeve and a dismantling sleeve. The cages use steel stamping cages, polyamide forming cages and copper alloy turning cages. The self-aligning ball bearing has two structures of cylindrical hole and conical hole, and the material of the cage is steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical, with automatic centering, which can compensate for the errors caused by non-concentricity and shaft deflection, but the relative inclination of the inner and outer rings should not exceed 3 degrees. It can bear large radial load and also bear certain axial load. The outer ring raceway of this type of bearing is spherical, so it has self-aligning performance. When the shaft is bent or tilted under force, so that the relative inclination of the center line of the inner ring and the center line of the outer ring does not exceed 1°~2.5°, the bearing can still work. .
The inner hole of self-aligning ball bearing has two types: cylindrical and conical. The taper of the conical bore is 1:1 2 or 1:30. In order to enhance the lubricating performance of the bearing, an annular oil groove and three oil holes are machined on the outer ring of the bearing.
Self-aligning ball bearing product features：
Mainly bear radial load, and can bear small axial load at the same time. The axial displacement of the shaft (housing) is limited within the clearance limit, and it has automatic centering performance. It allows normal operation under the condition that the inner and outer periphery are relatively inclination. It is suitable for the parts where the bearing seat hole cannot strictly guarantee the coaxiality.
Self-aligning ball bearing structure
The self-aligning ball bearing with dust cover and sealing ring has been filled with an appropriate amount of grease during assembly. It should not be heated or cleaned before installation. It does not need to be lubricated during use. It is suitable for operating temperature - 30 ℃ to + 120 ℃ between. Main uses of self-aligning ball bearings: suitable for precision instruments, low-noise motors, automobiles, motorcycles and general machinery, etc., and are the most widely used type of bearings in the machinery industry.
