4317 Series Steel, MOD 0.8 Miter Gear (8mm REX Bore, 24 Tooth)

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.

Miter gears are a specific type of a bevel gear that create a 1:1 ratio at 90° due to their 45° pitch cone angle. Though we also offer the larger 4315 Series Miter Gears, 4317 Series Miter Gears are sized for more intricate applications that benefit from compactness and lesser rotating mass!

This 8mm REX Bore Miter Gear is able to mesh with any other 4317 Series Miter Gear, regardless of bore size. Simply space the back of each miter gear 20mm from the center of the shaft driving the other miter gear, and make sure their shafts are at 90° to each other.

This miter gear’s 8mm REX bore (as seen in our 7203 Series Yellow Jacket Planetary Gear Motors) is the go-to for beefy, positive drive. Meanwhile, its two M5 set-screws—located on flats 120° apart—ensure that the gear will not move axially along a shaft, even in the most strenuous applications
