Deep Groove Ball Bearings SKF 6009 -Z/C3

The SKF 6009 -Z/C3 deep groove ball bearing, with dimensions of 45x75x16 mm, offers compact installation dimensions, increased C3 clearance and single-sided dust protection for industrial drives.

The 6009 -Z/C3 deep groove ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) in SKF’s Explorer design. With a bore of 45 mm, an outside diameter of 75 mm and a width of 16 mm, this radial ball bearing primarily accommodates radial loads as well as moderate axial loads. Thanks to the combination of a sheet steel cage and increased radial clearance, the bearing is suitable for applications involving thermal fluctuations or high speed requirements in industrial drive and conveyor technology.

In which applications does the 6009 -Z/C3 deep groove ball bearing prove its worth?

Preferred applications include industrial drives and rotating bearings where higher temperatures occur during operation. The single-row component covers a temperature range from –20 to +150 degrees. Designs with oil lubrication benefit from the open rear, through which lubricant can reach the rolling elements unhindered, whilst the metal cover plate on the opposite side prevents coarse dirt particles from entering.

What are the functions of the C3 bearing clearance and the Z-cover plate?

The designation C3 stands for a slightly increased radial bearing clearance. This internal clearance compensates for any interference fit on the shaft as well as thermal expansion of the rings during operation. The abbreviation ‘Z’ denotes a single-sided cover made of sheet steel. As this gap seal shields the inner ring without coming into contact with it, no additional friction losses occur, which facilitates high speeds without generating additional frictional heat.
