Deep Groove Ball Bearings SKF 6011

As an open roller bearing, this variant has neither sliding seals nor cover plates. This means that no additional friction losses are caused by sealing lips during operation, which facilitates high operating speeds. However, lubricants can escape unhindered to the outside and ambient media can enter the inside; for this reason, the bearing should operate in a sealed housing environment.

The standard radial bearing clearance corresponds to the standard operating clearance for single-row deep-groove ball bearings. It is dimensioned such that, after the bearing has been pressed onto the shaft and fitted into the housing bore, sufficient radial clearance remains. This design is suitable for standard applications with a balanced heat balance between the shaft and the housing.

The sheet steel cage keeps the rolling elements spaced apart and prevents the balls from coming into contact with one another. It is characterised by its low weight combined with high strength. Thanks to the open cage design, liquid lubricating oil or grease can reach the raceways unhindered, which aids heat dissipation during operation.

The roller bearing is designed for use at ambient temperatures ranging from -20 to +120 degrees Celsius. Within this temperature range, the components made from standard roller bearing steel (100Cr6) and the sheet steel cage retain their dimensional stability and shape. The actual limit value must always take into account the lubricant used.

Owing to the deep raceways in the inner and outer rings, the single-row bearing can accommodate radial loads as well as axial forces in both directions. As this is a general-purpose rolling bearing, it is suitable for rotating shafts subjected to combined loads, as is commonly the case in general mechanical engineering.
