Jatec22324CA Double Row Tapered Spherical Roller Bearing Self Aligning 120x260x86

22324CA/W33

The 22324CA/W33 is a spherical roller bearing designed for handling substantial radial and axial loads. It features a double-row roller configuration and a spherical outer raceway, which provides automatic alignment to compensate for shaft misalignment and deflection.

Key Features:

• Self-Aligning: The spherical outer raceway allows the bearing to automatically realign, accommodating shaft misalignment and angular errors.
• Load Capacity: Capable of supporting high radial loads as well as bidirectional axial loads.
• CA Construction: Includes a high-strength brass cage that offers durability, self-lubricating properties, and some plastic deformation capability.

This bearing is well-suited for applications in heavy machinery, mining equipment, and industrial settings where misalignment and heavy loads are common.

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.

Raw Material & Structure

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.

How to Install Spherical Roller Bearing?

Universal Failure Modes

1. The bearing is damaged when the aligning Angle is exceeded during installation.

2. When installing the bearing inner ring with the press, avoid the support under the outer ring to prevent the installation of the bearing when the bearing is pressed down, resulting in the crushing of the outer ring edge.

3. The installation axial was preloaded which causes damage to the aligning roller bearing.

4. Fracture of inner ring caused by large installation interference.

5. Poor lubrication leads to early wear of bearing raceway.
