440 Stainless steel double-row self-aligning ball bearings S1207

Stainless steel Aligning Ball Bearing is a Bearing fitted with spherical ball balls between the inner ring of two raceways and the outer ring of a spherical raceway.

The curvature center of the outer ring raceway surface is consistent with the bearing center, so it has the same self-aligning function as the automatic Self-Aligning Ball Bearing. In the case of shaft and housing deflection, it can be automatically adjusted without increasing the bearing burden. Self-Aligning Roller Bearing can bear radial load and axial load in two directions. Large radial load capacity, suitable for heavy load, impact load. The inner diameter of the bearing ring is taper hole, which can be mounted directly. Or use a tight set sleeve, disassembly cylinder to install on the cylindrical shaft. The cages are made of steel sheet stamping cages, polyamide forming cages and copper alloy car cages.

The stainless steel self-aligning Ball Bearing has two kinds of structure: cylindrical hole and conical hole, and the material of cage is steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical and has automatic self-aligning, which can compensate for the errors made by the self-aligning ball bearing with different concentricity and shaft deflection, but the relative inclination of the inner and outer rings shall not exceed 3 degrees.

Can bear large radial load, but also can bear a certain axial load. The outer ring raceway of this kind of bearing is spherical, so it has the performance of self-aligning. When the shaft is bent or tilted and the relative tilt of the center line of the inner ring and the center line of the outer ring is less than 1° ~ 2.5°, the bearing can still work.

Stainless steel self-aligning ball bearing inner hole has cylindrical and conical two kinds. The taper of the conical inner hole is 1:1 2 or 1:30. In order to strengthen the lubrication performance of bearings, annular oil grooves and three oil holes are processed on the outer ring of bearings.
