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 upon this we are able to select a wide variety of regular customizations to meet up the requirements of various properties that are important 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, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our product range with more than 1000 different standard gearboxes is most likely a good start to have the ability to deliver a product that stands out on your side.
Small gearboxes are high-quality gearboxes for regular drives. The electric engine is included with the gearbox right into a single unit (the first equipment is on the engine shaft). Individual gearboxes for connection to conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our professionals will be happy to help you make your selection. We will be happy to send you documentation or style the right set directly, on ask for.

Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix position is typically comparatively bigger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), 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, easily running and highly dynamic drive systems.
Our high-performance gear products are designed to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, producing them much sought after in the industry. Because of this 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 ensures optimum rolling get in touch with under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be utilized for the same torque, and smaller gears with remarkable power density also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing perform necessary for troublefree rolling contact to be substantially reduced and therefore the gear backlash to end up being minimized.
Dual chamber shaft seals developed by Ever-Power are used as regular in parallel shaft, shaft mounted 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
