We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to your flexible modular concept.
Based about this we are able to select a wide selection of common customizations to meet up the requirements of varied properties that are essential for each application.
If your application takes a gearbox with some special home such as small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of such properties, our product range with an increase of than 1000 different standard gearboxes is most likely an excellent start to be able to deliver something that stands out on your side.
Compact gearboxes are high-top quality gearboxes for standard drives. The electric motor is integrated with the gearbox into a single unit (the first equipment is directly on the 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 cannot be purchased inside our e-shop. Our specialists will be happy to help you make your selection. We will be pleased to send out you documentation or style the right set directly, on demand.

Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our success originated from our relentless get for level of quality with state-of-the-artwork technology, all while offering worm gearboxes will be affordable prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and electric motor interfaces, makes the Ever-Ability worm gearbox the default determination for the industry. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Electricity Worm gearboxes provide substantial torque with low quickness gear ratio. Being simple and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its own 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, side 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 are the electro-mechanical key components for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear models are designed to withstand the toughest industrial applications.
The gear 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 are often to be found as part of 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 ensures optimum rolling get in touch with 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 large gearing capacity enables smaller tires to be utilized for the equal torque, and smaller gears with exceptional power density also increase reliability. Ever-Electric power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play necessary for troublefree rolling contact to be substantially decreased and therefore the equipment backlash to be minimized.
Double chamber shaft seals produced by Ever-Power are used as standard during parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular equipment technology meets the requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
