Designs and variants
Spherical roller bearings have 2 rows of rollers, a common sphered outer ring raceway and 2 inner ring raceways inclined at an angle to the bearing axis.
The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for
example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.
Factors influence spherical roller bearing performance
Bearing performance is not only determined by load or speed ratings. There are a number of other factors that contribute to bearing performance. To a large extent, performance is influenced by the geometry of the rollers,
raceways and cages, the heat treatment, as well as the surface finish of all contact surfaces. Main factors which influence spherical roller bearing performance include, but are not limited to:
1.Symmetrical rollers
2.Roller tolerances
3.Special roller profile
4.Self-guiding rollers and a guide ring between the 2 rows of rollers
5.Metal cages
Basic design bearings
Depending on their series and size, standard spherical roller bearings are as following basic designs:
CC design bearings have 2 stamped window-type steel cages, an inner ring without flanges and a guide ring centred on the inner ring. The CC design is indicated by the
designation suffix C or CC. Large CC design bearings with the designation suffix EC or ECC have an optimized internal design for increased load carrying capacity.
CA design bearings have a machined double prong-type brass cage, an inner ring with a retaining flange on both sides and a guide ring centred on the inner ring. The flanges
on the inner ring are designed to keep the rollers in place when swivelling the bearing during installation or maintenance. The flanges are not designed to guide the rollers
or accommodate any axial load. The CA design is indicated by the designation suffix CA. Large CA design bearings with the designation suffix ECA have an optimized internal design for increased load carrying capacity.
E design bearings have 2 stamped window-type steel cages, an inner ring without flanges and a guide ring centred on the inner ring (d ≤ 65 mm) or on the cages (d > 65 mm). They have an annular groove and 3 lubrication holes in the outer ring. E design bearings are indicated by the designation suffix E. All E design bearings have an optimized internal design for increased load carrying capacity.
Annular groove and lubrication holes
Spherical roller bearings are available with an annular groove and 3 lubrication holes in the outer ring (designation suffix W33) or 3 lubrication holes in the outer ring (designation suffix W20) . E design bearings have an annular groove and 3 lubrication holes as standard and therefore, the W33 designation suffix is not necessary
Cages
Cages in spherical roller bearings are an integral part of the bearing internal design. Depending on their internal design, series and size, spherical roller bearings are fitted with 1 of the cages . For additional information about the suitability of cages, refer to Cages and Cage materials .

Maintenance Tips for Prolonging the Life of a Worm Gearbox
Proper maintenance is essential to ensure the longevity and reliable performance of a worm gearbox. Here are some maintenance tips to consider:
- Lubrication: Regularly check and replenish the lubricant in the gearbox. Use the recommended lubricant type and quantity specified by the manufacturer.
- Lubrication Schedule: Follow a lubrication schedule based on the operating conditions and manufacturer recommendations. Regular lubrication prevents friction, reduces wear, and dissipates heat.
- Temperature Monitoring: Keep an eye on the operating temperature of the gearbox. Excessive heat can degrade the lubricant and damage components.
- Cleanliness: Keep the gearbox and surrounding area clean from debris and contaminants. Regularly inspect and clean the gearbox exterior.
- Seal Inspection: Check for any leaks or damage to seals and gaskets. Replace them promptly to prevent lubricant leaks and contamination.
- Alignment: Ensure proper alignment between the worm and worm wheel. Misalignment can lead to increased wear and reduced efficiency.
- Torque Monitoring: Monitor the torque levels during operation. Excessive torque can cause overloading and premature wear.
- Regular Inspections: Periodically inspect all components for signs of wear, damage, or unusual noise. Replace worn or damaged parts promptly.
- Proper Usage: Operate the gearbox within its specified limits, including load, speed, and temperature. Avoid overloading or sudden changes in operating conditions.
- Expert Maintenance: If major maintenance or repairs are needed, consult the manufacturer’s guidelines or seek the assistance of qualified technicians.
By following these maintenance tips and adhering to the manufacturer’s recommendations, you can extend the lifespan of your worm gearbox and ensure its optimal performance over time.
Diagnosing and Fixing Oil Leakage in a Worm Gearbox
Oil leakage in a worm gearbox can lead to reduced lubrication, increased friction, and potential damage to the gearbox components. Here’s a step-by-step process to diagnose and fix oil leakage:
- Inspect the Gearbox: Perform a visual inspection of the gearbox to identify the source of the leakage. Check for oil stains, wet spots, or oil pooling around the gearbox.
- Check Seals and Gaskets: Inspect the seals, gaskets, and O-rings for any signs of wear, cracks, or damage. These components are common points of leakage.
- Tighten Bolts and Fasteners: Ensure that all bolts, screws, and fasteners are properly tightened. Loose fasteners can create gaps that allow oil to escape.
- Replace Damaged Seals: If you find damaged seals or gaskets, replace them with new ones. Use seals that are compatible with the operating conditions and lubricant.
- Check Breather Vent: A clogged or malfunctioning breather vent can cause pressure buildup inside the gearbox, leading to leakage. Clean or replace the breather vent if necessary.
- Examine Shaft Seals: Check the shaft seals for wear or damage. If they’re worn out, replace them with seals of the appropriate size and material.
- Use Proper Lubricant: Ensure that you’re using the correct lubricant recommended for the gearbox. Using the wrong type of lubricant can cause leaks.
- Apply Sealants: In some cases, applying a suitable sealant to the joints and connections can help prevent leaks. Follow the manufacturer’s instructions for proper application.
- Monitor Leakage: After addressing the issues, monitor the gearbox for any signs of continued leakage. If leakage persists, further investigation may be required.
- Regular Maintenance: Implement a regular maintenance schedule that includes checking seals, gaskets, and other potential leakage points. Timely maintenance can prevent future leakage issues.
If you’re unsure about diagnosing or fixing oil leakage in a worm gearbox, consider consulting with a professional or gearbox manufacturer to ensure proper resolution.
Preventing Backlash in a Worm Gearbox
Backlash in a worm gearbox can lead to reduced accuracy, positioning errors, and decreased overall efficiency. Here are steps to prevent or minimize backlash:
- High-Quality Components: Use high-quality worm gears and worm wheels with tight manufacturing tolerances. Precision components will help reduce backlash.
- Proper Meshing: Ensure the worm gear and worm wheel are properly aligned and meshed. Improper meshing can lead to increased backlash.
- Preload: Applying a small amount of preload to the worm gear can help reduce backlash. However, excessive preload can increase friction and wear.
- Anti-Backlash Mechanisms: Consider using anti-backlash mechanisms, such as spring-loaded systems or adjustable shims, to compensate for any inherent backlash.
- Lubrication: Proper lubrication can reduce friction and play a role in minimizing backlash. Use a lubricant that provides good film strength and reduces wear.
- Maintenance: Regularly inspect and maintain the gearbox to identify and address any changes in backlash over time.
It’s important to strike a balance between reducing backlash and maintaining smooth operation. Consulting with gearbox experts and following manufacturer guidelines will help you optimize your worm gearbox’s performance while minimizing backlash.
