Deep Groove Ball Bearings FAG 6217 -2Z

The FAG 6217 -2Z deep-groove ball bearing (85x150x28 mm) features sheet metal shields on both sides to protect against particles whilst maintaining a compact design.

The 6217-2Z deep groove ball bearing is a single-row rolling bearing designed primarily for radial loads. With an inside diameter of 85 mm, an outside diameter of 150 mm and a width of 28 mm, this design is suitable for a wide range of shaft constructions in mechanical engineering. Manufactured from standard roller bearing steel 100Cr6, the bearing complies with tolerance class P0/PN (ABEC 1). A guided sheet steel cage maintains an even spacing between the rolling elements and ensures smooth running.

In which applications is the 6217-2Z deep groove ball bearing used?

In terms of design, the 6217 -2Z deep-groove ball bearing is suitable for rotating shafts subjected to predominantly radial loads and moderate axial forces in both directions. The deep raceway geometry accommodates these combined force components. As the outer ring has no flange or groove, the component can be fitted flush into cylindrical housing bores. The permissible temperature range extends from –30 to +120 degrees Celsius, meaning the bearing can withstand the typical thermal conditions encountered in continuous industrial operation.

What is the function of the 2Z cover plates?

The double-sided cover with non-contacting sheet metal discs (designation 2Z) protects the interior of the bearing from coarse dirt particles and swarf. Unlike sliding seals, metallic gap seals do not generate any additional frictional heat on the rotating surfaces. The bearing is manufactured with standard radial bearing clearance. This specification is suitable for fits and operating conditions involving moderate heating, where no increased operating clearance is required.
