What Are SKF Single Row Spherical Roller Bearings?
SKF single row spherical roller bearings feature barrel‑shaped rollers arranged in a single row between the inner and outer rings. The raceway geometry allows the bearing to self‑align, meaning it can compensate for angular misalignment between the shaft and housing without excessive stress or loss of performance.
This combination of high load capacity and misalignment tolerance makes them a robust choice for demanding industrial environments.
Design and Options
SKF single row spherical roller bearings are available in various designs and configurations to suit different applications:
- Open and sealed designs – open bearings for standard conditions, sealed bearings for enhanced protection against contamination and better lubricant retention
- Different internal clearances – to accommodate operating temperatures and fits (e.g. C3, C4 clearances for higher temperatures or tighter fits)
- Alternative cage materials – such as steel or brass cages, selected according to speed, load and lubrication requirements
- Special variants – available for high‑temperature, vibrating or heavily contaminated environments
Acorn’s bearing specialists can help you choose the appropriate series, clearance and design variant based on your operating conditions.
SKF Single Row Spherical Roller Bearings FAQs
What is the difference between single row spherical roller bearings and double row spherical roller bearings?
Single row spherical roller bearings contain one row of barrel‑shaped rollers, while double row designs have two rows. Double row spherical roller bearings typically offer higher load capacity and can handle heavier combined loads, whereas single row designs can be a more compact, cost‑effective solution where load requirements are lower but misalignment still needs to be accommodated.
How do I select the correct internal clearance (e.g. C3, C4)?
Internal clearance is chosen based on operating temperature, shaft and housing fits and load conditions. Higher operating temperatures or tight fits typically require increased internal clearance (such as C3 or C4). Provide your operating conditions and we’ll recommend a suitable clearance class.
What lubrication should be used with SKF single row spherical roller bearings?
These bearings can be lubricated with grease or oil. The best choice depends on speed, load, temperature and environmental conditions. SKF provides specific lubricant recommendations for different series; our team can help you select both the correct lubricant and relubrication intervals.
