High Speed, High Load Capacity: Bearings for Screw Drives BSB..-SU-XL Single row axial angular contact ball bearings in X-life design, universal, with 60° contact angle

Longer rating life, higher speeds Universal bearings BSB..-SU-XL for high speed screw drives Features of the new X-life design Through the use of state-of-the-art Technical advantages of the new X-life design manufacturing techniques, axial angular The improved features offer a range of contact ball bearings BSB..-SU-XL in X-life design have the following features: ■ High dynamic load carrying capacity ■ Optimised contact face between the rolling elements and raceway ■ Increased raceway accuracy and Figure 1: Screw drive bearing arrangement with one bearing set, comprising three sealed and greased...

High basic load ratings C, Long grease operating life longer rating life Lhr Thanks to the technical changes, the surfaces, the material used for The reduced bearing friction in the basic dynamic load ratings C are the bearing rings is also subjected to axial angular contact ball bearings around 10% higher than those of special heat treatment. BSB..-SU-XL of X-life design and the previous bearing designs, Figure 3. As a result, the raceways of the inner and the associated reduction in heat gener- outer rings are more resistant to solid ation in the bearing permit high speeds. This also has the...

Modular concept offers standard designs The customer can select three different designs from one modular concept: Open bearings, not greased, suitable for oil lubrication or grease filling by the user Bearings with minimal gap seal on both sides, greased for life Open bearings, greased with multipurpose grease Arcanol Multitop (available by agreement). Sealed bearings BSB..-2Z-SU-XL Schaeffler offers all sizes in an X-life design with integral minimal gap seal (suffix 2Z). Advantages in detail: They are supplied greased with the multi-purpose grease Arcanol Multitop for optimum running characteristics,...

Bearing designations The designations of the universal bearings BSB..-SU-XL are constructed as follows, Figure 5. Marking of bearings The measured actual deviations of the inside and outside diameter are indicated not only on the box but also on the bearing itself, Figure 6. This means that grouping of bearings can be carried out, if necessary, even when the packaging is not present. Single row axial angular contact ball bearing with 60° contact angle, for screw drives Bore diameter_ Outside diameter_ BSB3062 -SU-XL BSB3062 -SU-XL-L055 BSB3062-2Z-SU-XL Greasing Greased with high performance grease...

Axial angular contact ball bearings Universal bearings for screw drives All sizes are available with greasing by agreement. Ordering example: BSB2562-SU-XL-L055. 2) Based on a preloaded bearing set comprising two greased bearings. 3) Guide value proven in practice for maximum speeds in applications for machine tools (approx. +50 °C bearing temperature for a proportion of 25% of the operating duration and at room temperature. The bearing is preloaded and free from external load).
