The MG528T/0.5M is a 28-tooth motor pinion designed for use with 48-pitch gear systems, specified at Module 0.5mm and a 5mm motor shaft bore. It is made for RC electric drive trains that employ 48-pitch gearing.
Use this pinion when replacing a worn part or when altering the drive ratio to 28T within a 48-pitch configuration. The 45-steel material delivers a durable mating face but correct mesh and alignment must be observed to avoid excess wear on mating gears.
Fitting guidance: ensure the motor shaft bore is 5mm, set axial position to reach proper mesh, secure the pinion fastener and check for endplay. Inspect tooth engagement and fastener security after first runs and adjust mesh slightly if needed for consistent operation.
Tuning perspective: selecting this 28T pinion adjusts the driven ratio by a known step, helping you trade off acceleration and top speed while remaining within the parameters of your motor and ESC on 48-pitch systems.
