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 selection of regular customizations to meet the requirements of varied 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 power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of such properties, our item range with more than 1000 different standard gearboxes is most likely a good begin to have the ability to deliver something that stands out in your favor.
Compact gearboxes are high-quality gearboxes for regular drives. The electric engine is included with the gearbox into a single unit (the first equipment is on the engine shaft). Individual gearboxes for link with conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they cannot be purchased in our e-shop. Our professionals will be happy to help you make your selection. We will be happy to send you documentation or design the right set directly, on request.

Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our achievement came 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 broad choice of mounting choices, shaft configurations and motor 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, add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low velocity gear ratio. Being simple and compact in style, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type qualities act like 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 could be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or double), 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, easily running and highly dynamic drive systems.
Our high-performance gear products are built to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, making them much sought after in the industry. As a result 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 simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact 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 excellent power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing enjoy necessary for troublefree rolling contact to be substantially decreased and then the gear backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are utilized as regular 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
