Description
Competition eligibility
Legal for FIRST Tech Challenge (FTC) and FIRST Robotics Competition (FRC). Eligibility is set by each season's game manual — check the current rules before you compete.
Being steel, these pinion gears provide greater overall strength (as compared to brass or aluminum) ,Transfer the torque of your servo into a gear train with these MOD 0.8 servo gears. This 40 tooth servo gear is most commonly used to drive the 80 tooth hub gear, spaced 48mm away, in order to create a 2:1 ratio. This gear reduction will increase the torque at the hub gear to 2x what the servo produces. This gear may also be used to drive a 20 tooth pinion gear spaced 24mm away for a 2:1 overdrive if you’re set out to increase the rotation of the servo.
