SKF double row deep groove ball bearings

SKF double row deep groove ball bearings correspond in design to single row deep groove ball bearings. Their deep, uninterrupted raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and axial loads in both directions.

SKF double row deep groove ball bearings are very suitable for bearing arrangements where the load carrying capacity of a single row deep groove ball bearing is inadequate. For the same bore and outside diameter, double row bearings are slightly wider than single row bearings in the 62 and 63 series, but have a considerably higher load carrying capacity.

SKF double row deep groove ball bearings

SKF double row deep groove ball bearings are fitted with two snap-type, ball centred glass fibre reinforced PA66 cages (designation suffix TN9). The lubricants generally used for rolling bearings do not have a detrimental effect on cage properties. However, some synthetic oils and greases with a synthetic oil base and lubricants containing EP additives, when used at high temperatures, can have a detrimental effect on polyamide cages.

SKF double row deep groove ball bearing data

Dimension standards Boundary dimensions: ISO 15:2011
Tolerances Normal
Internal clearance Normal, C3
Misalignment ≤ 2 minutes of arc
The permissible angular misalignment between the inner and outer rings depends on the size and internal design of the bearing, the radial internal clearance in operation and the forces and moments acting on the bearing. As a result, only approximate values are listed here. Any misalignment increases bearing noise and reduces bearing service life.
