Ever-Power Corporation , announces its right position NEMA gearbox designed to IP65 specs for use in wash straight down applications in packaging devices and comparable machinery. Rated backlash is certainly 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 input and output. All fasteners are stainless steel. Hard anodized aluminium or 316 Stainless housings can be found. Customizing for apart from NEMA motors or your specific application is 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 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 generates 16.2 Kg-cm of torque at 1.68 Amps.
When connected to a 1067 – EP, the 3317 has a maximum speed of a little over 900 RPM. At the result of the gearbox, the stage angle is just a little under 0.35°. When using the step position in calculations, you should derive the precise step position by dividing 1.8° by the gearbox reduction ratio.
This particular revision of the 3317 is manufactured by a different manufacturer, but should behave very much like 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 path with their slip fit “O” ring design. Low to high reduction ratios, flange install or foot mount types, right angle or hollow shaft right angle types available. Fit NEMA C-Encounter AC motors, brushless DC motors and brushed DC motors.

Longer Life
In comparison to a spur gear of approximately the same pitch diameter, Helical gears may transfer high loads at greater speeds. This is because of the gradual engagement of the teeth and soft transfer of the strain.
Helical Gears
Lightweight and Compact
Die cast aluminum equipment housings make these quickness reducers light in weight, allowing engineers to create more economical mounting provisions
Maintenance Free
High-quality synthetic grease is utilized in every gearboxes. They are loaded at the factory and do not need maintenance filling or level checks. This saves valuable time at create and eliminates concern for costly oil disposal needed by the EPA.
Mount in virtually any Direction
These gearboxes are sealed with machine “slip” suit “O” rings and dual lip spring shaft seals on both the motor and input shaft and output shaft driver. Thus, the gear motors can be mounted in any conceivable path without concern for the positioning of a breather connect.
