Heavy duty DA and DB Series gear motors maintain timing accuracy and are offered in a very
broad range of shaft speeds from 120 RPM through 24 RPD. These motors are recommended
especially for applications requiring high gear torque ratings (100 oz-in [706.2 mN-m] maximum)
and small size (DA case size: 2.5" [63.5 mm] dia. x 1.75" [44.5 mm] depth). Add 0.25" [6.35 mm]
to depth for DB case size.
Gear train materials include high quality bronze bearings, brass gears, hardened steel pinions
and wheel shafts.
Notes:
• A capacitor is required for operation and is supplied with 115V motors.
