30-Tooth Graham Escape Wheel With 608 Hub
An 80 mm, 30-tooth Graham (deadbeat) escape wheel for pendulum clocks and automata, with forward-raked teeth and a 22.05 mm press-fit pocket for a 608 bearing (8 x 22 x 7 mm) so it turns freely on an 8 mm arbor. It has five spokes and is 5 mm thick, keeping it light for low drive weights, and it pairs with an anchor that spans 7.5 teeth.
