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 on this we are able to select a wide selection of standard customizations to meet up the requirements of various properties that are essential for each application.
If your application takes a gearbox with some special residence such as for example 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 an increase of 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-quality gearboxes for regular drives. The electric electric motor is built-in with the gearbox into a single unit (the first gear is on the motor shaft). Individual gearboxes for link with conventional IEC motors may 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 pleased to help you create your selection. We are happy to send out you documentation or style the right set directly, on demand.

Ever-Power worm gearboxes possess 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 affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and motor 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, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low quickness gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix position is typically comparatively larger) and its body is normally quite lengthy 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 (single 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, smoothly running and highly powerful drive systems.
Our high-performance gear products are designed to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and invite diverse installation positions and applications, making them much sought after in the industry. Because of this our geared motors are often 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 supported simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root style in mixture 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 excellent power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing enjoy required for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are used as standard in parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets the requirements of advanced drive systems:
Excellent power density
Diverse mounting options
Precision Worm Gearboxes & Geared Motors
