Spline = Hitec Standard Spline
Width = 1/8” (.125”)
O.D. = Outside Diameter
P.D. = Pitch Diameter

Finally a way to drive gears using servos! Our patented 48 pitch gears are designed to attach directly to the output spline of a servo. These gears work great in combination with our hub mounted gears to drive axles or build pan and tilt mechanisms.

Uses C1 Standard Spline

Center-Center Distance	Total Tooth Count (48 Pitch)
A (0.75”)	72
B (1.5”)	144
C (2.25”)	216

Example: Using distance A (0.75”) with 48P gears
Total tooth count (pinion gear + spur gear) must equal 72
For an application that requires a 2:1 ratio:
24T pinion gear + 48T spur gear = 72 total tooth count
48 ÷ 24 = 2 (2:1 ratio)
