Learn about super duplex angular contact ball bearings from Schatz, a Made in USA bearing manufacturer that is ITAR certified and has an AS9100D / ISO 9001:2015 certified facility.
A super duplex angular contact ball bearing is a high-performance bearing designed for applications that require high positional accuracy and low torque. It is a design enhancement over a simple duplex angular contact ball bearing.
Schatz designs and manufactures these high-performance products in Poughkeepsie, New York (USA). Keep reading to learn more, and contact us for all of the angular contact bearings and custom bearings you need.
Configurations for Super Duplex Angular Contact Ball Bearings
These bearings can use either a face-to-face configuration or a back-to-back configuration. In both configurations, the bearing races set an internal preload.
Face-to-Face Configuration
In a face-to-face configuration, there are two outer rings and one inner ring. The inner ring has two raceways which are precision ground in the same manufacturing process to optimize race-to-race runouts and size variation.
Back-to-Back-Configuration
In a back-to-back configuration, there are two inner rings and one outer ring. The outer ring has two raceways which are precision ground in the same manufacturing process to optimize race to race runouts and size variation.
Bearing Races
The bearing races are precision preload ground to have a gap which closes at a predetermined axial force. This sets an internal preload into the bearing, which produces a high bearing stiffness in all axes while still maintaining low frictional torque.
Applications for Super Duplex Angular Contact Ball Bearings
These ball bearings are predominantly used in the aerospace and military and defense industries. They also find use in high-speed machinery and heavy-duty equipment.
Advantages Over Simple Duplex Angular Contact Ball Bearings Sets
Super duplex angular contact ball bearings are preferred over simple duplex angular contact ball bearings for three main reasons: ease of assembly, accuracy, and friction.
Ease of Assembly
Due to the integral nature of the two raceways, super duplex angular contact ball bearings cannot inadvertently be installed in the wrong orientation. This is a common problem for simple duplex angular contact ball bearings and can lead to system failure.
Accuracy
Super duplex angular contact ball bearings are manufactured using precision manufacturing processes for tighter race to race runouts. This offers more consistent bearing accuracy.
Friction
Due to the tighter race to race runouts, they provide less torque variation.
