Single-row radial contact ball bearings
The SNR single-row radial contact ball bearing range is suitable for the most diversified applications. Designed essentially to sustain moderate radial loads, these bearings, which are the most commonly used, also sustain moderate axial loads in all directions. They are particularly suitable for applications with high rotating speeds and when energy loss limitation is sought.
Thin-section ball bearings (ISO series)
In certain mechanical systems under low load rating, the ball bearing determined by the shaft diameter can be oversized in terms of load capacity. Bearing over sizing can introduce a weight and footprint penalty in the mechanical component's design. It is then advisable to resort to thin-section ball bearings.
These are rigid bearings, with a deep throat and no filling notch, capable of sustaining axial loads in both directions. Thanks to these properties, they are amongst the most economical and the most widely used bearings. They are essentially distinguished form the conventional series (16000, 6000, etc.) by their thin section and extremely low weight. Series 61800 are now available with sealings.
Increased width series
For high stress loading applications, SNR has designed a series of radial contact ball bearings featuring increased width. Fitted with a riveted steel cage and a dual, floating lip copper-asbestos seal, increased width bearings have an improved service life thanks to better pollution protection and more durable lubrication.
