What Are Spherical Roller Bearings Used For?
Spherical roller bearings are engineered to manage large radial loads, moderate axial loads, and continuous rotation even when misalignment occurs. Their unique design includes two rows of rollers that rotate within two raceways on the inner ring, with a shared spherical outer ring raceway. This enables smooth, consistent operation even if the shaft and housing are not perfectly aligned.
Typical uses include:
- Quarry and mining equipment
- Heavy conveyors and crushers
- Vibratory machines and compactors
- Gearboxes, fans, and marine propulsion systems
- High-load rotating shafts subject to impact or misalignment
- Two rows of rollers for greater load support
- Self-aligning design to correct for angular deviations
- Optional sealed versions to resist contamination
- Availability with brass cage for high-speed, high-temperature durability
- Adaptable to tapered sleeves or straight bore fits for flexible mounting
- Load direction: Will it support radial, axial, or combined loads?
- Speed and temperature: Is a brass cage or sealed version better for the environment?
- Mounting method: Will you use a tapered sleeve, adapter, or straight shaft?
- Misalignment risk: Will the bearing axis deviate during operation?
- Maintenance access: Do you need a long-life, low-maintenance option?
- Immediate UK stock
- Wide range of sizes and bearing types
- Trusted by clients across construction, mining, processing, and transport
- Technical advice available to help you specify the right product
- Fast dispatch and responsive service
These bearings are essential in applications where load capacity, resistance to contamination, and alignment flexibility are critical.
What Makes Spherical Roller Bearings Suitable for High Loads?
The key strength of spherical bearings lies in their ability to handle high radial loads and tolerate axial loads in either direction. Thanks to the rolling elements design and wide contact angles, they operate smoothly even when alignment is compromised due to shaft deflection, mounting errors, or shifting loads.
Main features include:
Our bearings are manufactured from robust materials, such as hardened steel, and are suitable for high-temperature and high-speed environments.
What Bearing Types and Sizes Are Available?
We supply a full selection of spherical roller bearings, including:
Standard Spherical Roller Bearings
Ideal for general use, supporting large radial loads with a self-aligning inner structure.
Spherical Roller Bearings with Brass Cage
Used in vibratory applications or where acceleration, friction, and high temperatures are present. These offer enhanced durability and precision.
Sealed Spherical Bearings
Pre-lubricated and protected against contamination, ideal for limited maintenance access and dusty environments.
Tapered Bore Bearings with Adapter Sleeves
Easy to mount and dismount in equipment with fixed shaft diameters. We offer a wide range of outside diameters, bore diameters, and cage designs to meet exact requirements. If you need support choosing the correct bearing type or configuration, our team is here to help.
Choosing the Right Spherical Roller Bearing for Your Equipment
To select the best bearing, consider:
If your setup involves angular misalignment, vibration, or heavy loads, most spherical roller bearings offer the ideal combination of strength and flexibility to deliver dependable performance.
