Self-aligning ball bearings have two rows of steel balls, inner ring has two raceways, outer ring raceway for the spherical type, with self-aligning performance. Can automatically compensate for the shaft deflection and shell deformation caused by the coaxial error, suitable for supporting the hole can not guarantee the concentricity of the parts. This kind of bearing mainly bear the radial load, can bear the radial load too at the same time, can also bear a small amount of axial load, usually not to bear the pure axial load, bear the pure axial load, only one steel ball Roller bearings with two rows of rollers, mainly used to bear radial load, but also can withstand any direction of the axial load. This kind of bearing has high radial load capacity, especially for heavy load or vibration load, but it can not bear pure axial load. It has good self-aligning performance and can compensate coaxial error. Technical staff with you to understand the characteristics of self-aligning roller bearings:
1, carrying capacity;
2, the main radial load, but also can withstand a certain axial load, but can not afford pure axial load;
3, aligning performance, to compensate for coaxial error;
4, the limit speed is low.
Spherical roller bearings in two raceway inner ring and raceway for the spherical outer ring, equipped with drum-shaped roller bearings. Outer ring raceway surface of the center of curvature and bearing the same, so with self-aligning ball bearings with the same self-aligning function. In the shaft, shell deflection occurs, you can automatically adjust the load and the axial load in both directions. Radial load capacity, suitable for heavy load, shock load situation. The inner diameter of the inner ring is tapered bore bearings that can be mounted directly. Or use an adapter sleeve that is mounted on the cylinder shaft. Cage use of steel stamping cage, polyamide forming cage and copper alloy car cage. Spherical roller bearings are divided into: cylindrical bore, conical bore.
Conical bore taper were 1:12 post-code-named K-aligning roller bearings (153000 or 113000 type) and 1:30 after the code-named K30-aligning roller bearings. Such bearings and conical shafts are arranged, the axial movement of the inner ring can adjust the bearing radial clearance. The main purpose: papermaking machinery, gear reducer, railway vehicles axle, rolling mill gear box seat, roller mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, various industrial reducer, .
Spherical roller bearings can withstand radial loads, but also can withstand any direction of the axial load. Has a high radial load capacity, especially for heavy duty or vibration load, but can not afford pure axial load.
