New bearings for high-speed applications
Fig. 1: Centrifugal compressor.
Bearings in the new SKF Explorer single-row angular contact ball bearing assortment with 25° contact angle, equipped with a new brass cage and an improved raceway geometry, can withstand much higher speeds (up to n×dm = 1,050,000 mm/min) and are more robust in severe operating conditions compared to SKF Explorer single-row angular contact ball bearings with 40° contact angle.
The new 25° contact angle assortment from bore diameter 15 mm up to 70 mm in the 72 AC series and from 17 mm to 70 mm in the 73 AC series was launched in April 2017 and is available from stock or in a short time.
Because of the modular single-row angular contact ball bearing design, customers can choose the most suitable cage, sealing and contact angle to design new compressor generations that are more efficient and reliable, to reduce total costs of ownership for the operators.
