The SKF JEM series deep groove ball bearing is a single-row design that handles radial and axial loads in both directions. You will find it in electric motors, pumps, fans and transmissions. MR Industrial Accessories supplies this bearing and helps you match the exact code to your application.
Break the JEM designation into its parts. Take 6309 JEM: the 6 is the series, the 3 is the diameter series and the 09 is the bore code. The JEM suffix points to a stamped, riveted steel sheet cage with an optimized design. That cage keeps the rolling elements in place and copes with the acceleration and temperature levels common in industrial service.
In US plants, JEM series bearings turn up in electric motors, centrifugal pumps, fans, compressors, conveyor belts and machine tools. Food, textile and chemical operations use them, as does metalworking. They run at high speeds with little maintenance, which suits equipment that stays online.
Selection starts with shaft diameter, load type and the surrounding conditions. Choose open, shielded or sealed based on contamination and whether you need to hold lubricant in. Follow the manufacturer's guidance for internal clearance and lubrication. When mounting, line up shaft and housing correctly and use the right tools so the rings are not damaged.
SKF JEM series bearings interchange with equivalent bearings from other makers that share the same standardized dimensions. For a replacement, check cage type, sealing and internal clearance along with the code. If anything is unclear, send us the original code plus shaft and housing dimensions. MR Industrial Accessories can help you pin down the right equivalent.
To get a quote, message us on WhatsApp with the full bearing code. If you do not have it, send shaft and housing dimensions, load type and working conditions. Our technical team responds with a suitable option and we arrange delivery.

Frequently asked questions
- SKF 6309 JEM bearing: what are its dimensions?
- SKF 6309 JEM measures 45 mm across the bore and 100 mm across the outside diameter; its width is 25 mm (45 x 100 x 25 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6309.
- What does the JEM suffix mean on an SKF bearing?
- JEM indicates a stamped, riveted steel sheet cage with an optimized design. It suits moderate and high speeds and guides the rolling elements well.
- How do I choose between an open and a sealed bearing?
- It comes down to the environment and maintenance. Open bearings allow relubrication and heat dissipation; sealed or shielded bearings keep lubricant in and contaminants out. Consider cleanliness, humidity and how accessible the equipment is.
- Can I replace an SKF bearing with another brand?
- Yes, if standardized dimensions and key characteristics match: cage type, sealing and internal clearance. Always check the code and dimensions before replacing. If in doubt, consult us with the equipment data.
