Split spherical roller bearings are a type of spherical roller bearing that can be easily installed and maintained. These bearings are designed to withstand heavy loads and high speeds, making them ideal for use in a wide range of industrial applications. In this article, we will take a closer look at split spherical roller bearings, including their design, features, and benefits.
The design of split spherical roller bearings
Split spherical roller bearings are designed to provide support for heavy radial and moderate axial loads in applications where the shaft and housing cannot be easily separated. They consist of a spherical outer ring and a cylindrical inner ring that are separated by a center groove, allowing them to be easily disassembled for maintenance or replacement.
The outer ring of the bearing has a spherical raceway, while the inner ring has two raceways that are inclined at an angle to the bearing axis. This design allows the bearing to accommodate shaft misalignment, which can occur due to manufacturing tolerances or deflections in the shaft or housing.
The rollers of the bearing are typically cylindrical in shape, with a crowned or barrel profile that helps to distribute the load evenly across the rollers. They are made of high-carbon steel and are hardened for durability.
The cage of the bearing is typically made of pressed steel or a polyamide material, and is designed to keep the rollers evenly spaced and properly aligned.
The design of split spherical roller bearing also includes the seal, that protect the bearing from external contaminants and retain the lubricant. The most common type of seal used on this type of bearing is a contact seal, which typically consists of a steel outer ring and a rubber inner ring.
Overall, the design of a split spherical roller bearing combines the high load capacity of a spherical roller bearing with the convenience of being able to be easily disassembled, making it a great solution for heavy-duty industrial applications that require regular maintenance.
Features of split spherical roller bearings
One of the key features of split spherical roller bearings is their ability to accommodate misalignment. Unlike standard bearings, which can only accommodate a small amount of misalignment, split spherical roller bearings can accommodate larger amounts of misalignment without causing damage to the bearing or the shaft. This makes them ideal for use in applications where the shaft may be subject to vibration or other forces that can cause misalignment.
Another important feature of split spherical roller bearings is their ability to withstand heavy loads. The rollers in these bearings are typically made of high-quality steel, which gives them a high load-carrying capacity. This makes them ideal for use in applications such as heavy equipment, mining, and construction.
Split spherical roller bearings also have a high speed capability, which makes them suitable for high-speed applications such as fans, conveyors and compressors. The raceway design of these bearings gives them a high level of stiffness and stability, which helps to reduce the impact of vibration and other forces on the shaft and bearing.
Maintenance of split spherical roller bearing
Split spherical roller bearings are designed to be easily disassembled, making them convenient for maintenance. Here are some steps for maintaining a split spherical roller bearing:
- Clean the bearing and its surrounding area before disassembly to prevent contamination of the bearing during the maintenance process.
- Carefully disassemble the bearing, taking note of the orientation of the components.
- Inspect the bearing and its components for signs of wear or damage, such as pitting, scoring, or excessive wear on the rollers or races. If any damage is found, the bearing should be replaced.
- Clean all components with a suitable solvent, then dry them thoroughly.
- Apply a small amount of lubricant to the bearing components, being careful not to over-lubricate.
- Reassemble the bearing, making sure that all components are properly oriented and seated.
- Test the bearing for proper operation after reassembly.
It is recommended that you follow the manufacturer’s guidelines for lubrication, cleaning and assembly. Also, you should check the recommended intervals for the check and maintenance of the bearings in the operations manual, that will help you maintain the bearing in optimal condition.
Application of split spherical roller bearing
Split spherical roller bearings are used in a wide range of industrial applications due to their ability to withstand heavy loads and high speeds, and accommodate misalignment. Some common applications include:
- Heavy equipment: Split spherical roller bearings are used in construction, mining, and agricultural equipment as they can withstand the heavy loads and vibrations encountered in these types of machinery.
- Power generation: Split spherical roller bearings are often used in power generation equipment such as turbines and generators, where they must handle high speeds and heavy loads.
- Metal and cement production: They are commonly used in equipment found in metal and cement production, such as crushers, kilns, and conveyors, to support high loads and withstand harsh operating environments.
- Paper and Pulp Industry: They are also used in various equipment in the paper and pulp industry, such as press rolls, calender rolls, and rewinders.
- Fans and compressors: Split spherical roller bearings can handle the high speeds and loads encountered in fan and compressor applications such as air conditioning systems and industrial refrigeration.
- Conveyors: They are also used in conveyors and material handling systems, where they help to support heavy loads and ensure smooth operation.
These are just a few examples of the many industries and applications where split spherical roller bearings can be found. They are known for its durability and ability to withstand harsh conditions, making them a reliable and cost-effective solution for many industries.
In conclusion, split spherical roller bearings are an excellent choice for many industrial applications due to its design, features, and benefits. With easy installation and maintenance, high load-carrying capacity, and the ability to accommodate misalignment and high speeds, split spherical roller bearings are a cost-effective and reliable option for many industries.
