We deliver worm gearboxes, spur gearboxes and planetary gearboxes with as well as without integrated linear lead screw / ball screw adapted to your flexible modular concept.
Based in this we can select a wide variety 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 property or home such as small dimensions or low weight with regards to vitality, 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 product 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-top 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 electric motor shaft). Separate gearboxes for connection to conventional IEC motors can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased in our e-shop. Our experts will be pleased to help you make your selection. We are pleased to send out you documentation or design a suitable set directly, on request.

Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our success came from our relentless travel for quality with state-of-the-art 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, would make the Ever-Electricity worm gearbox the default determination for the industry. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide excessive torque with low speed gear ratio. Being simple and compact in design, 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 position is typically comparatively bigger) and its own body is normally quite long in the axial path. The gears in these gearboxes could be ideal or left-handed depending upon the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary or double), 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 dynamic drive systems.
Our high-performance gear models are built to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse installation positions and applications, making them much sought after in the industry. Consequently our geared motors are often to be found as part of 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 get in touch with 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 substantial gearing capacity enables smaller tires to be utilized for the exact torque, and smaller gears with exceptional power density also increase reliability. Ever-Electricity geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing enjoy necessary for troublefree rolling contact to be substantially reduced and therefore the equipment backlash to become minimized.
Double chamber shaft seals developed by Ever-Power are utilized as standard during parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
