Deep Groove Ball Bearings FAG 6308 -N

The 6308-n deep-groove ball bearing from FAG Wälzlager is a single-row rolling bearing with an outer diameter of 90 mm and a width of 23 mm, offering a robust solution for rotating shafts.

The 6308-n deep groove ball bearing is a single-row radial ball bearing made from standard rolling-bearing steel, which accommodates radial forces as well as axial forces in both directions. The cylindrical bore allows for direct mounting on suitable shaft seats. Thanks to the deep groove geometry, the rolling elements run with low vibration and low friction within the ring, which promotes uniform concentricity in rotating assemblies.

What loads and operating conditions can the 6308-n deep-groove ball bearing accommodate?

The 6308-n deep groove ball bearing is primarily designed for radial loads; however, due to its design, it also accommodates axial forces in both directions. Its design for a temperature range of –30 to +120 °C allows operation under demanding thermal conditions in industrial environments. Lubrication via the housing is required to ensure smooth running, as open bearings do not have an integrated lubricant fill.

What are the advantages of the sheet steel cage and the open design?

As an open design, this ball bearing has no integrated seals, allowing lubricating oil or grease to flow unhindered to the rolling elements and raceways. This design is suitable for clean installation environments or external housing seals. The integrated sheet steel cage guides the rolling elements precisely and maintains a uniform spacing between them. In conjunction with the standard radial bearing clearance, this results in stable operating behaviour with standard fit selections.
