Product Overview
The SKF 22316E is a high-performance double-row spherical roller bearing with relubrication features, designed for demanding industrial applications requiring exceptional load capacity and self-aligning capabilities. As part of the SKF Explorer performance class, this bearing combines advanced engineering with robust construction to deliver reliable operation even under severe conditions.
Key Features
- Self-aligning design: Accommodates misalignment (up to 0.5°) and shaft deflections with virtually no increase in friction or operating temperature
- Heavy load capacity: Handles high radial loads and significant bidirectional axial loads
- Relubrication optimization: Features an outer ring lubrication groove and holes for easy maintenance and extended service life
- Low friction: Engineered roller geometry minimizes energy loss and wear
- Durable construction: Sheet metal cage ensures stability and reliability in challenging environments
- SKF Explorer class: Premium performance level with enhanced material quality and manufacturing precision

Applications
The SKF 22316E is ideal for:
- Conveyor systems and material handling equipment
- Vibratory machinery and screening plants
- Pumps, compressors, and fans
- Gearboxes and industrial transmissions
- Paper and pulp processing machinery
- Mining and construction equipment
- Wind turbine components
Its self-aligning capability makes it particularly suitable for applications where shaft misalignment may occur due to installation errors, thermal expansion, or structural deflection.
Installation & Maintenance
- Designed for easy mounting with cylindrical bore (interference fit recommended)
- Relubrication points allow for in-service maintenance without disassembly
- Compatible with SKF modular mounting systems (housings, sleeves, and nuts)
- Recommended operating temperature range: -20°C to +120°C (with appropriate lubrication)
- Optimal performance achieved with SKF high-quality lubricants matched to application conditions
