Parallel Shaft Gearhead

SIEGMA 5GN3K

SIEGMA 5GN3K is a 90 mm square parallel shaft gearhead with a 3:1 ratio for SIEGMA GN-pinion AC motors (40, 60 W). It gives 600 r/min output at 60 Hz with a 4-pole motor and up to 0.92 N·m (8.14 lb-in) of permissible torque, depending on the motor. Equivalent to Oriental Motor 5GN3KA (current Oriental Motor numbering: 5GN3SA): matched on frame size and gear ratio.

Typical uses are conveyors, indexers, packaging machinery and food processing equipment.

Mounting

Mounts to the standard 90 mm GN/GU frame — same bolt pattern as Oriental Motor and other major brands (104 mm bolt circle).

Output shafts are not standardized across brands: this gearhead has a 12 mm (0.472 in) h7 shaft with a 4 mm key. Check it against the dimension drawing before fitting a coupling, pulley or sprocket.

A motor and gearhead must share the same frame size and pinion type; use this gearhead with SIEGMA GN-pinion motors.

Features
  • Metric 12 mm (0.472 in) h7 output shaft with a 4 x 4 x 25 mm key
  • Accepts SIEGMA GN-pinion motors, 90 mm frame
