Oriental Motor 5GVR12.5B – KII Series Parallel Shaft Gearhead, 90 mm, 12.5:1, for 90 W Motors
The Oriental Motor 5GVR12.5B is a KII Series parallel shaft gearhead with a 12.5:1 gear ratio, a 90 mm (3.54 in) frame and a metric 18 mm output shaft. It is designed for Oriental Motor GVR-type pinion shaft motors in the 90 mm, 90 W class, such as the 5IK90GVR induction motors.
The 5GVR12.5B reduces motor speed by a factor of 12.5 and increases output torque. With the 90 W 5IK90GVR-UA induction motor at 115 VAC and 60 Hz, it gives a rated speed of 144 rpm and a rated torque of 6.6 N·m (58 lb-in). It suits conveyors, packaging machines and general-purpose drives that need solid torque from a compact 90 mm drive.
