Ever-Power Company , announces its right angle NEMA gearbox made to IP65 specs for use in clean straight down applications in packaging apparatus and comparable machinery. Rated backlash is usually 30 arc-minutes with choices for 4 or 8 arc-minutes. The NEMA 34 flanged gearbox has 440C Stainless steel bearings with seals and Nitrile o-rings shaft seals on both insight and result. All fasteners are stainless steel. Hard anodized light weight aluminum or 316 Stainless housings can be found. Customizing for other than NEMA motors or your specific application is quickly done.
This Nema 17 stepper motor with 39mm body and 1.68A rated current, integrated with a 41mm Planetary gearbox of 5:1 equipment ratio. It’s a great choice to applications that with unique space but need low rate and/or high torque.

Replaced by the 3325_0, a electric motor with the same NEMA size and same torque.
This NEMA-17 motor comes with an integrated Planetary gearbox with a 52/11 :1 ratio. It creates 16.2 Kg-cm of torque at 1.68 Amps.
When connected to a 1067 – EP, the 3317 includes a maximum quickness of just a little over 900 RPM. At the output of the gearbox, the step angle is just a little under 0.35°. With all the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio.
This specific revision of the 3317 is made by a different manufacturer, but should behave very similarly to the revision 0 version.

Longer Life
In comparison to a spur gear of approximately the same pitch diameter, Helical gears can transfer high loads in greater speeds. That is because of the gradual engagement of the teeth and smooth transfer of the load.
Helical Gears
Lightweight and Compact
Die cast aluminum equipment housings make these speed reducers light in weight, allowing engineers to design more economical mounting provisions
Maintenance Free
High-quality synthetic grease is utilized in all gearboxes. They are packed at the factory , nor need maintenance filling or level checks. This saves valuable time at setup and eliminates concern for pricey oil disposal required by the EPA.
Mount in virtually any Direction
These gearboxes are sealed with machine “slip” fit “O” rings and dual lip spring shaft seals upon both the motor and input shaft and output shaft driver. Therefore, the gear motors can be mounted in virtually any conceivable direction without concern for the positioning of a breather connect.
