These cylindrical DC geared motors with rust are available in a wide range of ratios and with five different motors (two power ratings of 6 V motors and three power ratings of 12 V motors). The gearmotors all have the same 25mm diameter housing and 4mm diameter output shaft, so it is generally easy to replace one version with another when your design requirements change (although the length of the gearbox tends to increase with the gear ratio). All versions are also available with an integrated 48 CPR quadrature encoder on the motor shaft.

Note: Overtightening or overloading gearmotors can greatly shorten their service life and even lead to immediate damage. For these gearboxes, an upper torque limit of 15 kg cm (200 oz-in) is recommended; we strongly recommend keeping the applied loads well below this limit. Standstills can also lead to rapid (usually within seconds) thermal damage to the motor windings and braids, especially in versions with high power HP motors; a general recommendation for operation with DC motors with standby is 25% or less of the standstill current.
