Machined NEMA 8 vacuum adapters
2021-02-15: In stock
Price is per 1 adapter, comes 2x with M2 screws. 2 screws stay in the NEMA motor, and two are removed to install the supplied screws when attaching the new design adapters.
1/4" NPT version:
Machined from 6061 T6 aluminum, these adapters allow you to supply vacuum to a hollow shaft NEMA 8 stepper motor. The top of the adapter is threaded 1/4" NPT so you can use a push-to-connect fitting (NOT SUPPLIED) for your vacuum tubing. The bottom of the adapter features a sealed bearing that provides a partial seal to the motor shaft so no sealant is required!
4mm Push-to-connect version:
Integrated push to connect fitting for 4mm OD tube. A sealed bearing under provides some sealing against the motor shaft without adding resistance to the rotation of the NEMA 8 motor.
