We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based upon this we are able to select a wide selection of regular customizations to meet 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 with regards to power, high efficiency, quiet and vibration-free operation, extended life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of this kind of properties, our product range with an increase of than 1000 different standard gearboxes is probably a good start to have the ability to deliver something that stands out in your favor.
Small gearboxes are high-quality gearboxes for regular drives. The electric motor is integrated with the gearbox right into a single unit (the first equipment is on the motor shaft). Separate gearboxes for connection to 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 experts will be happy to help you create your selection. We are happy to send out you documentation or design the right set directly, on ask for.

Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the industry. 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 rate gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively larger) and its own body is generally quite long in the axial path. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single 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 units are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, producing them much sought after in the industry. Because of this our geared motors are often to be found within our customers own machines.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design supported by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling get in touch with under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity enables smaller tires to be utilized for the same torque, and smaller sized gears with remarkable power density also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing enjoy required for troublefree rolling get in touch with to be substantially reduced and then the gear backlash to become minimized.
Double chamber shaft seals produced by Ever-Power are used as regular in parallel shaft, shaft mounted and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive systems:
Excellent power density
Diverse mounting options
