Spherical Roller Bearings CC
Features
Spherical roller bearings have two rows of spherical rollers, the outer ring has a common concave spherical raceway, the inner ring has two concave raceways inclined at an angle to the bearing axis, and the center of curvature of the outer ring raceway is Bearing center is the same. The spherical roller bearing is self-aligning and is not affected by the misalignment of the shaft and the bearing housing or the deformation and deflection of the shaft, and can compensate for the concentricity error caused thereby. In addition to bearing radial load, this type of bearing can also bear bidirectional axial load and its combined load, with large bearing capacity and good anti-vibration and impact resistance.
Spherical roller bearings have 2, standard (N), 3, 4 and 5 sets of internal clearances, while tapered bore spherical roller bearings use 3 sets of clearances as the standard clearance. Bearings larger or smaller than the standard value of clearance can also be produced according to user requirements.
Vibration machinery bearings need to use larger radial clearance, 3, 4 groups or non-standard clearance between 3 and 4.
The spherical roller bearing for vibrating screen has 4 sets of clearance.
Easy to install:
Spherical roller bearings have two types of inner holes: cylindrical and conical. The taper of the conical taper hole is 1:12 and 1:30. This conical inner hole bearing is equipped with an adapter sleeve or a withdrawal sleeve. The tapered inner bore spherical roller bearing can be easily and quickly assembled on the optical shaft or stepped machine shaft.
