Ever-Power Corporation , announces its right position NEMA gearbox designed to IP65 specs for use in clean down applications in packaging products 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-bands shaft seals on both input and result. All fasteners are stainless steel. Hard anodized aluminum or 316 Stainless housings are available. Customizing for other than NEMA motors or your specific application is very easily done.
This Nema 17 stepper motor with 39mm body and 1.68A rated current, integrated with a 41mm Planetary gearbox of 5:1 gear ratio. It’s a good solution to applications that with unique space but require low swiftness and/or high torque.

Replaced by the 3325_0, a engine 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 generates 16.2 Kg-cm of torque at 1.68 Amps.
When connected to a 1067 – EP, the 3317 includes a maximum acceleration of a little over 900 RPM. At the output of the gearbox, the stage 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 particular revision of the 3317 is made by a different manufacturer, but should behave very similarly to the revision 0 version.
Brother Gearmotors NEMA C-Face Speed Reducers
The gears in these NEMA C-Face speed reducers are high strength, free of maintenance and can be mounted in any direction with their slip fit “O” ring design. Low to high reduction ratios, flange mount or foot attach types, right angle or hollow shaft correct angle types available. Suit NEMA C-Face AC motors, brushless DC motors and brushed DC motors.

Longer Life
Compared to a spur gear of around the same pitch size, Helical gears may transfer high loads in greater speeds. That is because of the gradual engagement of one’s teeth and easy transfer of the strain.
Helical Gears
Lightweight and Compact
Die cast aluminum gear housings make these velocity reducers light in weight, allowing engineers to design less expensive mounting provisions
Maintenance Free
High-quality synthetic grease is utilized in every gearboxes. They are stuffed at the factory , nor need maintenance filling or level checks. This saves precious time at set up and eliminates concern for expensive oil disposal needed by the EPA.
Mount in virtually any Direction
These gearboxes are sealed with machine “slip” suit “O” rings and double lip spring shaft seals on both motor and insight shaft and result shaft driver. Hence, the gear motors can be mounted in any conceivable direction without concern for the positioning of a breather connect.
