Deep Groove Ball Bearings SKF 6009 -2RS1/C3

The SKF 6009 -2RS1/C3 deep groove ball bearing, measuring 45x75x16 mm, offers compact protection against dirt and reliably compensates for thermal expansion.

This single-row deep groove ball bearing 6009 -2RS1/C3 combines radial load-carrying capacity with reliable sealing for continuous industrial operation. The SKF brand bearing in the Explorer version is made from standard 100Cr6 rolling-element bearing steel and features a dimensionally stable sheet steel cage. With key dimensions of a 45 mm bore, 75 mm outside diameter and 16 mm width, the component can be fitted precisely into suitable housings. The enhanced manufacturing accuracy to tolerance class P6 also ensures consistent concentricity.

What is the 6009-2RS1/C3 deep groove ball bearing suitable for in operation?

The bearing is well-suited for use in industrial drives, gearboxes and rotating shafts that primarily have to withstand radial forces and moderate axial forces. Thanks to its permissible operating temperature range of –20 to +120 degrees Celsius, the unit can cope with demanding environmental conditions. The cylindrical outer ring, which has no flange or groove, allows for flexible installation in smooth bearing seats. Typical applications include situations where the ingress of dirt must be prevented whilst frictional heat is generated.

When is the combination of a 2RS1 seal and C3 clearance advisable?

The factory designation 2RS1 stands for sealing discs that abrate against both sides, making it difficult for moisture or foreign particles to penetrate. At the same time, the system retains the lubricant inside the bearing. The increased radial bearing clearance (C3) reliably compensates for thermal expansion of the materials between the shaft and the housing. Choose this specification if your design requires tight fits or if temperature differences occur during operation that would reduce the internal bearing clearance.
