Precision gear for Teradek RT lens motors

This 0.8-mod wide 32-pitch gear mounts directly on the RT MK3.1 or MK3.0 lens motor to drive cine-style or ENG lenses. The 0.5 inch (12 mm) gear width provides a secure interface for focus or iris control on professional camera rigs. It is built for operators who need reliable mechanical coupling between motor and lens.

Passive mechanical component

The gear has no active electronics, so it draws no power and produces no heat or noise during operation. Thermal management and acoustic performance are determined entirely by the attached lens motor and camera system. No electrical consumption or cooling considerations apply to this accessory itself.

Questions about this item

How is the 0.8-mod wide 32-pitch gear fitted onto the RT MK3.1 lens motor and which step is often missed?

Slide the 12 mm gear onto the motor shaft, align the keyway, then tighten the set screw — the step many skip is confirming the key seats fully before locking it down

What maintenance will the 32-pitch gear need after extended use with cine-style lenses?

Periodically check the set-screw torque and inspect the 0.8-mod teeth for wear; replace the gear if the pitch shows rounding or backlash increases
