Deep Groove Ball Bearings FAG 6217

The FAG 6217 single-row deep-groove ball bearing (85x150x28 mm) accommodates both radial and axial loads and operates with standard bearing clearance.

As a single-row radial ball bearing, the 6217 is one of the most versatile machine components for rotating shafts. Manufactured from standard roller bearing steel 100Cr6, this component supports shafts with a diameter of 85 mm in housings with a 150 mm bore. The deep raceways in the inner and outer rings accommodate not only predominantly radial loads but also axial forces in both directions. Thanks to its open design, the bearing can be integrated directly into lubrication circuits.

What loads and operating conditions does the 6217 deep-groove ball bearing accommodate?

This bearing supports rotating machine parts with medium to large shaft diameters that are subject to combined loads. The 28 mm wide version provides a robust guide for rotating components. As the outer ring has neither a flange nor a ring groove, the cylindrical ring fits flush into smooth housing bores. The combination of a sheet steel cage and rolling elements made from standard rolling-bearing steel ensures smooth concentricity.

What are the advantages of the open design with a sheet steel cage?

The open design without integrated sealing washers allows unhindered exchange of grease or lubricating oil with the surrounding system. The guided sheet steel cage maintains a constant spacing between the balls, reduces internal friction and saves weight compared with solid cages. The bearing is designed for a temperature range of -20 to +150 degrees Celsius. For operation, the housing must be externally sealed against dirt and moisture to prevent premature wear of the raceways.
