The SKF deep groove ball bearing of the JEM series is a single-row bearing, designed to support radial and axial loads in both directions. It is used in electric motors, pumps, fans and transmissions. At MR Accesorios Industriales we carry it as a brand and advise you so you choose the exact code for your application.
The JEM series designation is read in parts. The main number, as in 6309 JEM, indicates the size and dimension series: the 6 corresponds to series 6, the 3 to diameter series 3 and the 09 to the bore code. The suffix JEM identifies a stamped, riveted steel sheet cage with an optimized design. This cage guides the rolling elements and withstands the accelerations and temperatures usual in industrial applications.
In Argentine industry, JEM series deep groove ball bearings are found in electric motors, centrifugal pumps, fans, compressors, conveyor belts and machine tools. They are common in food, textile and chemical plants and in the metalworking sector. Their ability to run at high speeds and their low maintenance make them suitable for continuously operating equipment.
To select the correct bearing, verify the shaft diameter, the type of load and the environmental conditions. The sealing can be open, shielded or sealed; choose according to contamination and the need to retain lubricant. Internal clearance and lubrication must follow the manufacturer's recommendations. During mounting, ensure correct alignment between shaft and housing, and use suitable tools to avoid damaging the rings.
SKF JEM series bearings are interchangeable with equivalent bearings from other brands that follow the same standardized dimensions. When replacing, compare not only the code but also the cage type, sealing and internal clearance. If you have doubts, consult us with the original code and the shaft and housing dimensions. At MR Accesorios Industriales we can help you identify the right equivalent.

Frequently Asked Questions
- What are the dimensions of the SKF 6309 JEM bearing?
- The SKF 6309 JEM bearing has a 45 mm bore, a 100 mm outside diameter and a 25 mm width (45 x 100 x 25 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6309.
- What does the suffix JEM mean on an SKF bearing?
- The suffix JEM indicates a stamped and riveted steel sheet cage with an optimized design. This cage is suitable for applications with moderate and high speeds, and allows good guiding of the rolling elements.
- How do I choose between an open and a sealed bearing?
- It depends on the environment and maintenance. Open bearings allow relubrication and better heat dissipation; sealed or shielded bearings retain lubricant and protect against contaminants. Consider cleanliness, humidity and equipment accessibility.
- Can I replace an SKF bearing with another brand?
- Yes, if the standardized dimensions and key characteristics match: cage type, sealing and internal clearance. Always verify the code and dimensions before replacing. If you have doubts, consult us with the equipment data.
