German Brammer bearings Brammer models Brammer prices
Brammer bearings can simultaneously withstand radial and axial loads. They can operate at higher speeds. The larger the contact angle, the higher the axial load capacity. The contact angle is the angle between the line connecting the contact points of the ball and raceway in the radial plane and the perpendicular to the bearing axis. High-precision and high-speed bearings typically use a 15 degree contact angle. Under axial force, the contact angle increases. Brammer bearing applications Single-row angular contact ball bearings: machine tool spindles, high-frequency motors, gas turbines, centrifugal separators, front wheels of small cars, differential pinion shafts, booster pumps, drilling platforms
German Brammer coupling Brammer model Brammer price
Brammer couplings consist of components such as an internal gear ring with the same number of teeth and a flanged half-coupling with external teeth. External teeth are available in two tooth profiles: straight teeth and crowned teeth. Crowned teeth refer to external teeth machined into a spherical surface, with the center of the sphere on the gear axis. The backlash is larger than that of standard gears. Crowned tooth couplings allow greater angular misalignment (compared to straight-tooth couplings), improve tooth contact conditions, increase torque transmission capacity, and extend service life. During operation of gear couplings, relative displacement occurs between the two shafts, and the tooth surfaces of the internal and external gears periodically slide axially relative to each other, inevitably forming
