Deep Groove Ball Bearings SKF 609 /C3

The SKF 609/C3 deep groove ball bearing, with dimensions of 9x24x7 mm, increased C3 clearance and high running accuracy, ensures precise concentricity in compact industrial drives.

The SKF 609/C3 deep groove ball bearing is a single-row radial ball bearing in the Explorer design for compact installation spaces. With a bore of 9 mm, an outside diameter of 24 mm and a width of 7 mm, the rolling bearing primarily accommodates radial loads as well as moderate axial loads. Manufactured from standard 100Cr6 rolling-bearing steel and guided by a sheet steel cage, the design retains its dimensional stability at operating temperatures ranging from –20 to +150 degrees.

What are the typical operating conditions for the open deep-groove ball bearing 609/C3?

It is particularly recommended for use in compact rotating shaft assemblies and small drives where low friction and high speeds are paramount. As an open bearing, this design does not require integrated cover plates or sealing discs, which minimises frictional resistance. Designs featuring external housing seals, a lubricating oil circuit or targeted relubrication benefit from this unobstructed access to lubricant. The combination of a compact size and a robust sheet steel cage supports smooth, continuous operation in industrial assemblies.

What are the advantages of the C3 bearing clearance and tolerance class P6/P5?

The suffix /C3 indicates a slightly increased radial bearing clearance. This increased clearance between the balls and raceways helps to prevent seizing if temperature differences occur between the inner and outer rings during operation, or if tight fits cause the ring to expand. Furthermore, the bearing is characterised by dimensional accuracy to Class P6 and running accuracy to Class P5. These tight manufacturing tolerances ensure low-vibration shaft operation and contribute to even load distribution.
