Deep Groove Ball Bearings SKF 6009

The SKF 6009 deep groove ball bearing offers precise running characteristics with main dimensions of 45x75x16 mm for demanding radial loads in mechanical engineering.

The 6009 deep groove ball bearing is a versatile single-row radial ball bearing made from standard rolling-element steel (100Cr6). As an open variant, the component is designed for external lubrication circuits or oil-lubricated systems. Thanks to its manufacture to SKF Explorer quality, the component features an internally optimised geometry. The integrated sheet steel cage guides the rolling elements at operating temperatures between –20 and +120 degrees. The design, which has no flange or groove on the outer ring, facilitates cylindrical mounting in standardised housing bores.

What is the SKF 6009 deep groove ball bearing suitable for?

Design engineers and maintenance personnel primarily use this design in rotating systems that mainly accommodate radial forces and low axial forces. Typical applications include shaft bearings and mechanical drive units with predominantly radial loads. As the component is of an open design, the lubricant reaches the raceways unimpeded. This is advantageous in applications with circulating oil bath lubrication or regular relubrication. Furthermore, as there are no contact seals, the bearing operates with low frictional resistance.

What does the tolerance class P6 mean for the 6009 deep groove ball bearing?

This radial ball bearing is manufactured to the enhanced tolerance class P6 (comparable to ABEC 3). The dimensional and concentricity tolerances are tighter than those of standard bearings, which contributes to smooth running and low vibration. In combination with the standard radial bearing clearance, the component is suitable for applications involving uniform thermal loads and requiring precise concentricity. During design, care must be taken to ensure a precise fit between the shaft and the housing bore in order to utilise the bearing’s guidance quality.
