Ever-Power Company , announces its right angle NEMA gearbox designed to IP65 specs for use in wash down applications in packaging devices and similar machinery. Rated backlash is 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 output. All fasteners are stainless. Hard anodized aluminium or 316 Stainless housings can be found. Customizing for apart from NEMA motors or your unique 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 gear ratio. It’s a great choice to applications that with special space but need low quickness and/or high torque.

Replaced by the 3325_0, a 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 linked to a 1067 – EP, the 3317 includes a maximum speed of a little over 900 RPM. At the result of the gearbox, the step angle is a little under 0.35°. When using the step angle in calculations, you should derive the specific step position by dividing 1.8° by the gearbox decrease ratio.
This specific revision of the 3317 is made 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 may be mounted in virtually any path with their slip fit “O” ring style. Low to high decrease ratios, flange mount or foot install types, right angle or hollow shaft correct angle types available. Match NEMA C-Face AC motors, brushless DC motors and brushed DC motors.

Longer Life
Compared to a spur equipment of around the same pitch diameter, Helical gears can transfer high loads at greater speeds. That is due to the gradual engagement of one’s teeth and clean transfer of the strain.
Helical Gears
Lightweight and Compact
Die cast aluminum gear housings make these swiftness reducers light in weight, allowing engineers to create less expensive mounting provisions
Maintenance Free
High-quality synthetic grease is used in every gearboxes. They are packed at the factory and do not require maintenance filling or level checks. This saves valuable time at set up and eliminates concern for expensive oil disposal necessary by the EPA.
Mount in Any Direction
These gearboxes are sealed with machine “slip” fit “O” rings and double lip spring shaft seals upon both motor and input shaft and output shaft driver. Thus, the gear motors can be mounted in virtually any conceivable path without concern for the positioning of a breather plug.
