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 upon this we can select a wide variety of regular customizations to meet up the requirements of varied properties that are important for each application.
If your application requires a gearbox with some special house such as 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 this kind of properties, our product 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 device (the first gear is directly on the engine shaft). Individual gearboxes for connection to conventional IEC motors can 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 out you documentation or design a suitable set directly, on ask for.

Special wishes possible
Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are inexpensive prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the sector. The helical-worm and the double-worm version, 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 swiftness gear ratio. Being simple and compact in style, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix position is typically comparatively bigger) and its own body is generally quite long in the axial direction. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, easily running and highly powerful drive systems.
Our high-performance gear devices are designed to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse installation positions and applications, producing them much popular in the industry. Consequently 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 simply 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 allows 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 as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play required for troublefree rolling contact to be substantially decreased and therefore the gear backlash to be minimized.
Double chamber shaft seals produced by Ever-Power are used as standard in parallel shaft, shaft mounted and helical worm gears for a higher 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
