We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to our flexible modular concept.
Based on this we can select a wide selection of standard customizations to meet the requirements of various properties that are essential for each application.
If your application requires a gearbox with some special property or home such as small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, extended 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 probably a good start to have the ability to deliver a product that stands out on your side.
Compact gearboxes are high-quality gearboxes for regular drives. The electric electric motor is included with the gearbox into a single unit (the first gear is on the electric motor shaft). Separate gearboxes for connection to conventional IEC motors can also be supplied on request.
Because of 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 you documentation or style the right set directly, on ask for.

Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are inexpensive prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and 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, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low rate gear ratio. Being basic and compact in style, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type qualities are similar to helical gears, but its helix position is typically comparatively larger) and its body is generally quite long in the axial path. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or dual), with torque arm or torque limiter.
Top Quality 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 units are built to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse mounting 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 style in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be utilized for the same torque, and smaller sized gears with outstanding power density can also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing enjoy necessary for troublefree rolling contact to be substantially decreased and therefore the gear backlash to be minimized.
Dual chamber shaft seals produced by Ever-Power are used as regular in parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
