2303 Series Steel, MOD 0.8 Pinion Gear (1/4" Round Bore, 20 Tooth)

This 20 tooth pinion gear has a ¼” bore to fit on a ¼” round or D-profile shaft. When installed on a ¼” D-shaft, the M5 x 0.8mm set-screw tightens down onto the flat side of the shaft for an excellent hold.

The built-in shim allows this gear to run directly against a ¼” ID bearing without contacting the outer race.
