GER MOTORS I TECHNICL INFORMTION 43 Outrigger bearing assembly SNM2NN n outrigger bearing is available for applications with high radial or thrust loads on the shaft. This option is used primarily for applications with high shaft loads. The design utilizes roller bearings in the front mounting flange. These bearings absorb the radial and thrust loads on the shaft so that the life of the motor is not affected.
