We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to your flexible modular concept.
Based upon this we are able to select a wide selection of standard customizations to meet the requirements of various properties that are essential for each application.
If your application takes a gearbox with some special property such as small dimensions or low weight in relation 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 mixture of this kind of properties, our product range with more than 1000 different standard gearboxes is probably a good begin to have the ability to deliver something that stands out on your side.
Small gearboxes are high-quality gearboxes for standard drives. The electric motor is built-in with the gearbox right into a single unit (the first gear is directly on the engine shaft). Individual gearboxes for connection to conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our experts will be happy to help you create your selection. We are happy to send you documentation or style the right set directly, on ask for.

Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm reduction 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 lengthy in the axial direction. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key components for low backlash, efficiently running and highly Compact Worm Gearbox powerful drive systems.
Our high-performance gear models are built to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and invite diverse installation positions and applications, producing them much sought after in the industry. Consequently our geared motors are often to be found as part of 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 ensures 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 allows smaller tires to be used for the same torque, and smaller sized gears with outstanding power density also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing perform necessary for troublefree rolling contact to be substantially decreased and then the gear backlash to end up being minimized.
Double chamber shaft seals developed by Ever-Power are utilized 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
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
