380:1 Micro Metal Gearmotor HPCB 12V with Extended Motor Shaft

This gearmotor is a miniature high-power, 12 V brushed DC motor with long-life carbon brushes and a 379.17:1 metal gearbox. This version has stainless steel gearbox plates instead of the standard brass ones for increased durability and resistance to wear from radial loads. The gearmotor has a cross section of 10 × 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter. This version also has a 4.5 × 1 mm extended motor shaft.
