Split spherical roller bearings are primarily used to support shafts in locations that are difficult to access. They find typical applications in various industries, including material handling equipment, conveyors, ventilation systems, steel rolling mills, ships, and paper production. In this article, we will discuss the knowledge related to the installation of split spherical roller bearings, particularly when replacing conventional bearings with adapter sleeves.

Understanding the Replacement of Bearings with Adapter Sleeves and Installation in Split Bearing Housings:

Split spherical roller bearings are commonly used as replacements for conventional spherical roller bearings with adapter sleeves. The condition for replacement is that the outer diameter, outer ring width, and diameter must remain the same.

These split spherical roller bearings can be installed in split bearing housings without requiring any additional mechanical modifications. This applies to other manufacturers' bearing housings as well, provided the internal dimensions are the same.

1. The installation space for split spherical roller bearings (top) is the same as that for conventional bearings with adapter sleeves (bottom), making the replacement process straightforward.

2. The installation of split spherical roller bearings is easy, involving simple checks and quick procedures, as they fit into the existing bearing housings.

3. Bearings with integrated locking rings have the same internal design as verified E1 designs.

4. Split spherical roller bearings are equipped with a solid cage made of glass-fiber-reinforced polyamide or brass and an integrated locking ring.

5. For specific applications, split spherical roller bearings with separate, split-lock rings are available.

Characteristics of Split Spherical Roller Bearings:

1. Split spherical roller bearings feature a cylindrical inner bore. The inner and outer rings, along with the roller-retaining cage, are divided into two halves and secured together with screws.

2. Most split spherical roller bearings are based on the proven design of E1 spherical roller bearings. The only difference is the presence of rigid center ribs on the inner ring of some larger bearings.

3. These bearings are equipped with solid cages made of glass-fiber-reinforced polyamide or brass (suitable for high-temperature applications).

4. Split spherical roller bearings have the same standard tolerances as non-split radial bearings and the normal internal clearance of non-split spherical roller bearings with cylindrical bores (DIN 620).

5. In most cases, the locking ring is integrated into the inner ring.

Steps for Installing Split Spherical Roller Bearings:

1. Support the weight of the rotor.

2. Remove the bearing housing cover.

3. Disassemble the old bearing (cutting the conventional bearing with adapter sleeves using a cutting machine is recommended).

4. Place half of the outer ring under the bearing housing, align it with the inner ring mounted on the shaft, and then tighten both inner rings together using screws.

5. Install the remaining components and place the upper half of the outer ring.

6. Lower the shaft to load the bearing.

7. Install the upper part of the bearing housing.

Please note that these steps are a general guide. Always refer to the specific bearing model and the detailed installation instructions provided by the manufacturer. Improper installation may lead to equipment failure or accidents and can reduce the bearing's lifespan and performance. Ensure you understand all necessary safety measures and correct operating procedures before proceeding with the installation.
