Overview
The SKF 6309JEM is a high-performance, non-shielded deep groove ball bearing engineered for demanding industrial applications. Single row deep groove ball bearings are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. The 6309 JEM Bearing is constructed with a single row of balls, a deep groove raceway in the outer ring, and is known for its robustness and durability. This lot of three bearings provides a reliable power transmission solution for machinery requiring consistent, efficient operation.
Key Features
- Single-row deep groove design for optimized radial and axial load handling
- High load-carrying capacity: it can support heavier radial loads compared to other types of ball bearings
- Non-shielded open closure for easy inspection and relubrication
- Capable of handling both radial and axial loads simultaneously
- Steel construction with precision-ground raceways for accurate performance
- Low friction operation reduces noise and vibration in rotating equipment
