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 variety of regular customizations to meet up the requirements of varied properties that are essential for each application.
If your application requires a gearbox with some special real estate such as small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, extended life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of this kind of properties, our item range with more than 1000 different standard gearboxes is probably a good begin to have the ability to deliver a product that stands out in your favor.
Small gearboxes are high-quality gearboxes for standard drives. The electric engine is included with the gearbox into a single device (the first gear is on the motor shaft). Individual 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 experts will be happy to help you make your selection. We will be happy to send you documentation or style a suitable set directly, on request.

Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are inexpensive prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and electric 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, 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 perform higher gear ratio than 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 body is normally 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.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key elements for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear products 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. As a result 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 simply 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 materials used and surface finish maximizes load capacity. This high gearing capacity allows 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 consequently 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 gear backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are utilized 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
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
