Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.

SKF Bearing W 639, the SKF bearing catalogue lists a large range of designs, variants and sizes of deep groove ball bearings. Beyond our catalogue offering, the SKF Explorer deep groove ball bearings are customizable to offer advantages for applications with specific performance needs.

Single row deep groove ball bearings are the most widely used bearing type. They are available capped (with seals or shields) or open. Open bearings that are also available capped may have recesses in the ring side faces.

SKF Bearing W 639, SKF inch bearings in the EE(B), RLS and RMS series are intended as aftermarket items and, therefore, SKF recommends not using these bearings for new bearing arrangement designs.

For bearing selection and technical details refer to the product table.
SKF can also supply bearings with a tapered bore. For detailed information.
Stainless steel deep groove ball bearings are corrosion resistant when exposed to moisture and several other media. They are available capped (with seals or shields) or open. Open bearings that are also available capped may have recesses in the ring side faces.
These bearings have a lower load carrying capacity than same-sized bearings made of high chromium steel.
For bearing selection and technical details refer to the product table and set the filter "Design" to "Single row, stainless steel".
Single row deep groove ball bearings with filling slots have a filling slot in both the inner and outer rings to accommodate more balls than standard deep groove ball bearings. Filling slot bearings have a higher radial load carrying capacity than bearings without filling slots, but their axial load carrying capacity is limited. They are also unable to operate at the same high speeds as bearings without filling slots.
Deep groove ball bearings with filling slots are available open or with shields on one or both sides. They are also available with or without a snap ring groove. Open bearings that are also available with shields may have recesses in the outer ring.
Large size deep groove ball bearings with filling slots, without cage, are available on request.
For bearing selection and technical details refer to the product table and set the filter "Design" to "Single row with filling slots".
Double row deep groove ball bearings are very suitable for bearing arrangements where the load carrying capacity of a single row 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.
Double row deep groove ball bearings are only available as open bearings (without seals or shields).
For bearing selection and technical details refer to the product table and set the filter "Design" to "Double row".
SKF double row deep groove ball bearings are fitted with two snap-type, ball centred glass fibre reinforced PA66 cages
When used at high temperatures, some lubricants can have a detrimental effect on polyamide cages. For additional information about the suitability of cages, refer to Cages.
