nema gearbox

Ever-Power Corporation , announces its right angle NEMA gearbox made to IP65 specs for use in clean down applications in packaging devices and comparable machinery. Rated backlash is 30 arc-minutes with options 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 result. All fasteners are stainless. Hard anodized 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 gear ratio. It’s a good solution to applications that with special space but require low velocity 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 linked to a 1067 – EP, the 3317 has a maximum acceleration of just a little over 900 RPM. At the output of the gearbox, the stage angle is a little under 0.35°. When using the step angle in calculations, you should derive the exact 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 direction with their slip fit “O” ring style. Low to high reduction ratios, flange install or foot attach types, right position or hollow shaft right angle types available. Fit NEMA C-Encounter AC motors, brushless DC motors and brushed DC motors.

Longer Life
Compared to a spur gear of around the same pitch diameter, Helical gears can transfer high loads at greater speeds. This is due to the gradual engagement of the teeth and soft transfer of the load.
Helical Gears
Lightweight and Compact
Die cast aluminum equipment housings make these acceleration 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 filled at the factory and don’t need maintenance filling or level checks. This saves valuable time at set up and eliminates concern for pricey oil disposal necessary by the EPA.
Mount in virtually any Direction
These gearboxes are sealed with machine “slip” suit “O” rings and dual lip spring shaft seals upon both the motor and insight shaft and output shaft driver. Therefore, the gear motors can be mounted in any conceivable direction without concern for the position of a breather plug.
