We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear lead screw / ball screw adapted to your flexible modular concept.
Based on this we can select a wide selection of regular customizations to meet up the requirements of various properties that are essential for each application.
If your application takes a gearbox with some special house such as for example small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our item range with more than 1000 different standard gearboxes is probably a good start to be able to deliver a product that stands out on your side.
Compact gearboxes are high-quality gearboxes for regular drives. The electric electric motor is built-in with the gearbox into a single unit (the first equipment is on the electric motor shaft). Individual gearboxes for link with conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our professionals will be happy to help you create your selection. We are happy to send out you documentation or style a suitable set directly, on ask for.

Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a broad choice of mounting options, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low quickness gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively larger) and its own body is normally quite long in the axial direction. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key components for low backlash, smoothly running and highly dynamic drive systems.
Our high-performance gear devices are built to withstand the toughest commercial applications.
The gear housings are machined on all sides and permit diverse mounting positions and applications, making them much popular in the industry. Because of this our geared motors tend to be to be found within our customers own devices.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design backed by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be used for the same torque, and smaller gears with excellent power density also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing enjoy required for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to become minimized.
Dual chamber shaft seals developed by Ever-Power are utilized as standard in parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive systems:
Excellent power density
Diverse mounting options
