We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to our flexible modular concept.
Based on this we are able to select a wide variety of standard customizations to meet the requirements of varied properties that are important for each application.
If your application requires a gearbox with some special property such as small dimensions or low weight with regards 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 mixture of this kind of properties, our product range with an increase of than 1000 different standard gearboxes is probably a good begin to be able to deliver a product that stands out in your favor.
Compact gearboxes are high-quality gearboxes for standard drives. The electric electric motor is built-in with the gearbox right into a single device (the first equipment is directly on the engine shaft). Separate 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 in our e-shop. Our professionals will be pleased to help you create your selection. We are happy to send you documentation or design a suitable set directly, on ask for.

Ever-Power worm gearboxes possess earned a status to be an industry benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and engine 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, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration 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 position is typically comparatively larger) and its body is generally quite long in the axial direction. The gears in these gearboxes could 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. Obtainable in Solid shafts (solitary or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key components for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear units 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. 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 supported simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact 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 high gearing capacity allows smaller tires to be utilized for the same torque, and smaller sized gears with extraordinary power density can also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing perform necessary for troublefree rolling get in touch with to be substantially decreased and then the gear backlash to be minimized.
Dual chamber shaft seals developed by Ever-Power are used as regular in parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
