Introduction
The self-aligning ball bearing is a bearing fitted with spherical ball bearings between the inner ring of the two raceways and the outer ring of the raceway.
Since the center of curvature of the raceway surface of the outer ring is the same as the center of the bearing, it has the same aligning function as the self-aligning ball bearing. When the shaft and housing are flexed, they can be automatically adjusted without increasing the bearing load. Spherical roller bearings can withstand radial loads and axial loads in both directions. Radial load capacity, suitable for heavy load, shock load conditions. The inner diameter of the inner ring is a tapered hole bearing that can be mounted directly. Or use an adapter sleeve and a removal cylinder to install on the cylinder shaft. The cage uses a steel stamped cage, a polyamide shaped cage and a copper alloy cage.
Self-aligning ball bearings have two types of structures, cylindrical bores and conical bores. The cages are made of steel plates and synthetic resins. Its characteristic is that the raceway of the outer ring is spherical and has self-aligning property. It can compensate the misalignment and shaft deflection to adjust the error of the ball bearing, but the relative inclination of the inner and outer rings must not exceed 3 degrees.
Can withstand large radial loads, but also can withstand a certain amount of axial load. This type of bearing outer ring raceway is spherical, so it has centering performance, when the shaft is forced to bend or tilt so that the inner ring centerline and the outer ring centerline relative tilt no more than 1 ° ~ 2.5 °, the bearing can still work .
Self-aligning ball bearings have cylindrical and conical holes. The conical bore has a taper of 1:1 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and three oil holes are machined on the outer ring of the bearing.
Product Features
It mainly bears radial load and can bear smaller axial load. The axial displacement of the shaft (housing) is limited to the clearance limit, and it has self-aligning performance. It allows the inner and outer periphery to work normally under relatively slanting conditions. It is suitable for parts whose bearing hole cannot strictly guarantee the coaxiality.
structure type
Dustproof caps and self-aligning ball bearings with seals have been filled with the proper amount of grease, and should not be heated or cleaned prior to installation. No relubrication is required during use. The operating temperature is - 30 °C to + 120 °C. between. Self-aligning ball bearings Main uses: Suitable for precision instruments, low noise motors, automobiles, motorcycles and general machinery, etc. It is the most widely used type of bearing in the mechanical industry.
