Single row deep groove ball bearings are particularly versatile. They are simple in design, non-separable, suitable for high and even very high speeds and are robust in operation, requiring little maintenance. Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads, even at high speeds.
Single row deep groove ball bearings are the most widely used bearing type. Consequently, they are available from SKF in many executions and sizes:
–open basic design bearings
–ICOS® oil sealed bearing units
–bearings with snap ring groove, with or without snap ring
Other deep groove ball bearings for special applications, shown in the “Engineering products” and “Mechatronics” sections, include:
–high temperature bearings
–bearings with Solid Oil
–polymer ball bearings
The SKF product range also includes bearings with a tapered bore. This variant is not included in this catalogue. Information will be provided on request.
SKF single row deep groove ball bearings are manufactured as standard to Normal tolerances.
SKF Explorer single row deep groove ball bearings are produced to higher precision than the ISO Normal tolerances. The dimensional accuracy corresponds to P6 tolerances, expect the width tolerance, which is considerably tighter and reduced to
–0/–60 μm for bearings with outside diameter up to 110 mm
–0/–100 μm for larger bearings.
The running accuracy depend on the bearing size and corresponds to
–P5 tolerances for bearings up to a 52 mm outside diameter
–P6 tolerances for bearings above 52 mm up to 110 mm outside diameter
–Normal tolerances for larger bearings.
For bearing arrangements where accuracy is a key operational factor, some SKF single row deep groove ball bearings are also available with accuracy completely to P6 or P5 tolerance class specifications. The availability of these bearings should always be checked before ordering.
The tolerances for classes Normal, P6 and P5 are in accordance with ISO 492:2002.
