Overview
The SKF 6313 JEM is a radial deep groove ball bearing engineered for high-performance industrial applications. This single-row bearing features a 65mm bore diameter, 140mm outer diameter, and 33mm width, delivering robust load capacity in a compact form factor. The open closure design accommodates standard lubrication methods and is widely used in electric motors, gearboxes, and mechanical power transmission systems.
Key Features
- Single-row deep groove design for reliable radial and light axial load handling
- Open closure (unsealed) allowing easy access for maintenance and relubrication
- Steel cage construction rated ABEC 1 precision for industrial duty
- Alloy steel rings and balls for extended service life and corrosion resistance
- Compatible with standard SKF lubrication schemes (MT47 grease recommended)
- Straight cylindrical bore for direct shaft mounting
Technical Specifications
The SKF 6313 JEM meets ISO 15 deep groove ball bearing standards and delivers consistent performance across industrial environments. Dynamic radial load capacity is 97.5 kN, making it suitable for moderate to high-speed applications. The bearing operates with minimal friction and low noise, critical for precision machinery.
Typical Applications
- Electric Motors: Both industrial and household motor spindles
- Pumps & Compressors: Centrifugal and rotary equipment
