We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or maybe without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based in this we can select a wide selection of standard customizations to meet the requirements of various properties that are important for each application.
If your application takes a gearbox with some special property such as for example small dimensions or low weight in relation to electricity, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, tension 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 start to be able to deliver something that stands out on your side.
Small gearboxes are high-top quality gearboxes for standard drives. The electric electric motor is integrated with the gearbox into a single unit (the first gear is on the motor shaft). Individual gearboxes for connection to conventional IEC motors can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our specialists will be happy to help you create your selection. We will 
be happy to send you documentation or style a suitable set directly, on demand.

Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes will be affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and electric motor interfaces, causes 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 an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration gear ratio. Being basic and compact in design, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix position is typically comparatively bigger) and its body is generally quite long in the axial direction. The gears in these gearboxes can be best 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-Electrical power gearboxes and geared motors are the electro-mechanical key components for low backlash, efficiently running and highly dynamic drive systems.
Our high-performance gear systems are built to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, producing them much sought after in the industry. As a result our geared motors tend to be to be found as part of 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 backed by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This excessive gearing capacity enables smaller tires to be utilized for the same torque, and smaller sized gears with exceptional power density can also increase reliability. Ever-Vitality geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play necessary for troublefree rolling contact to be substantially reduced and therefore the gear backlash to end up being minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as standard in parallel shaft, shaft mounted and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
