Structure
Spherical roller bearings with tapered bore bore with the rear code K and K30 installed on the matching adapter sleeve become rear code K+H type and K30+H type bearings. These bearings can be mounted on a smooth shaft without a shoulder and are suitable for applications where the bearing needs to be mounted and dismounted frequently. In order to improve the lubrication performance of the bearing, there are annular oil grooves in the outer ring of the bearing and three evenly distributed oil holes are drilled, the post-code is W33.

Advantages
1. The radial load capacity is large. Easy to install, can be installed directly or use the tight sleeve, assembly cylinder installed on the cylindrical shaft.
2. Can bear a certain axial load. The outer ring raceway of this kind of bearing is spherical and can bear large radial load. Therefore, it has the aligning performance, which is not affected by the misalignment of shaft and bearing box or shaft deformation and deflection, and can compensate the coaxiality error.
3. With two rows of spherical rollers, the outer ring has a common concave spherical raceway, the inner ring has two concave raceway inclined to an Angle with the bearing axis, the center of curvature of the outer ring raceway is consistent with the bearing center.
4. In addition to bear radial load, but also can bear two-way axial load and its combined load. The bearing capacity is large, and it has good vibration resistance and impact resistance.
Scope of application
Widely used in papermaking machinery, reducers, railway vehicle axles, rolling mill gearbox bearing housing, rolling mill rolls, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers and other industries.
