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 on this we are able to select a wide variety of standard customizations to meet up 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 with regards 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 this kind of properties, our item range with an increase of than 1000 different standard gearboxes is probably a good begin to be able to deliver something that stands out on your side.
Compact gearboxes are high-quality gearboxes for regular drives. The electric electric motor is integrated with the gearbox right into a single device (the first gear is directly on the electric motor shaft). Separate gearboxes for link with conventional IEC motors may 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 pleased to help you create your selection. We are happy to send out 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-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 engine interfaces, makes the Ever-Power worm gearbox the default choice for the sector. 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 speed gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities are similar to helical gears, but its helix angle is typically comparatively larger) and its own body is generally quite long in the axial path. The gears in these gearboxes could 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. Available 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 elements for low backlash, smoothly 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 permit diverse mounting positions and applications, producing them much popular in the industry. Consequently our geared motors tend to be 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 backed by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root style in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity enables smaller tires to be used for the same torque, and smaller sized gears with outstanding power density can also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing play required for troublefree rolling get in touch with to be substantially decreased and then the gear backlash to be minimized.
Double chamber shaft seals produced by Ever-Power are utilized as standard in parallel shaft, shaft installed and helical worm gears for a higher 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
