Deep Groove Ball Bearings SKF 6009 -2Z

The SKF 6009-2Z deep groove ball bearing, with dimensions of 45x75x16 mm, offers protection against foreign particles on both sides whilst ensuring low-friction operation.

This single-row deep-groove ball bearing 6009 -2Z primarily accommodates radial loads as well as moderate axial loads in both directions. Manufactured from through-hardened 100Cr6 rolling-element bearing steel in the SKF Explorer performance class, the bearing features non-contacting sheet steel cover plates on both sides. A guided sheet steel cage keeps the rolling elements evenly distributed in the deep raceways, whilst the cylindrical outer ring is designed without a groove or flange.

In which applications does the 6009-2Z deep-groove ball bearing prove its worth?

Designs with rotating shafts benefit from the properties of non-contact gap seals, as these do not generate any additional frictional heat. Designed for operating temperatures ranging from –20 to +120 degrees Celsius, the bearing unit is suitable for many industrial shaft arrangements. The Explorer-grade version is optimised for high fatigue strength under continuous operating conditions.

As the unit does not have integrated electrical insulation, care must be taken to ensure a suitable surrounding structure is in place for electrical units. The deep-groove ball bearing supports radial loads and combined axial loads without the need for separate adjustment work on the bearing seat.

What features do cover plates and tolerance class P6 offer?

The designation 2Z indicates sheet steel cover plates on both sides, which prevent lubricant leakage and keep solid particles out of the bearing interior. As the sheet metal covers do not come into contact with the inner ring, the rolling bearing achieves speeds on a par with open designs. Manufacture to tolerance class P6 (ABEC 3) ensures tighter dimensional and form tolerances than the standard tolerance, which supports precise concentricity on the 45 mm shaft.

In conjunction with the standard radial bearing clearance, the P6 class enables reproducible assembly with standard shaft-to-housing fit combinations.
