Goteborg, Sweden, April 26, 2017: SKF high performance, high reliability Explorer bearings series added new members: SKF single row angular contact ball bearings. By optimizing the interior design of the bearing, the bearing performance is improved comprehensively, and it can help the compressor, pump and gearbox industry to improve the performance of the whole machine, thus further reducing the overall life cycle cost of the equipment.

 

By improving the design of copper cage for bearing, the 40 degree angular contact ball bearing in SKF Explorer level reduces noise and vibration level and improves performance. Compared with the previous design, the limit speed increased by 30%.

 

The bearing uses a new cage shape and a stronger brass material to reduce its contact stress, improve the strength of the cage, and increase the acceptance of the impact load and vibration, so as to ensure that the bearing runs in a more stringent working environment at a higher speed.

 

In addition to designing an improved 40 degree contact angle series, SKF Explorer single row angular contact ball bearings also provide a 25 degree contact angle series. Compared with the 40 degree version, the 25 degree contact angle is further increased by 20% at the rotational speed to withstand higher radial loads. In the two versions of the 40 and 25 degrees, the contact configuration of the ball to the cage can achieve lower working temperature and better geothermal stability, while the noise and vibration level of the bearing are reduced by 15%. For inconvenient maintenance applications, customers can choose the seal angle contact ball bearings in this series, which can prevent pollutants from entering the bearings during installation and subsequent operation.

 

The bearing of the SKF Explorer grade single angle contact ball bearing can also be used in 40 and 25 degree bearing groups, of which 40 degree contact angle bearing bears the main axial load, and the 25 degree contact angle bearing is used as the backup bearing. The bearing group is suitable for the existence of bidirectional axial force, in which the axial force of one direction is the main load, it can be prevented from preparing. The phenomenon of slippage is caused by insufficient bearing load, thus achieving longer service life.

 

SKF Explorer grade bearings are the achievements achieved in the field of bearing design, tribology, metallurgy, lubrication and machining technology, which have been developed and accumulated for many years. For the screw compressor, pump and gear box for low working temperature, high speed, high energy efficiency and high bearing reliability, the new 40 and 25 Explorer level single angle contact ball bearing is a very attractive choice to help their products stand out in the competition.
