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 at this we can select a wide variety of common customizations to meet the requirements of varied properties that are important for each application.
If your application takes a gearbox with some special real estate such as for example small dimensions or low weight in relation to ability, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, force or temperature, integrated linear screw, or a mixture 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 in your favor.
Compact gearboxes are high-top quality gearboxes for standard drives. The electric motor is included with the gearbox into a single unit (the first gear is on the engine shaft). Separate gearboxes for connection to 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 specialists will be pleased to help you create your selection. We are happy to send you documentation or design the right set directly, on request.

Ever-Power worm gearboxes have earned a reputation to be a business benchmark worldwide. Our achievement originated from our relentless get for level of quality with state-of-the-artwork technology, all while offering worm gearboxes will be affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, will make the Ever-Ability worm gearbox the default personal preference for the market. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Vitality Worm gearboxes provide excessive torque with low acceleration gear ratio. Being basic and compact in style, these gears can perform higher gear ratio compared to 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 own body is normally quite long in the axial path. The gears in these gearboxes can be ideal or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Vitality gearboxes and geared motors are the electro-mechanical key components for low backlash, smoothly running and highly dynamic drive systems.
Our high-performance gear units are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse mounting positions and applications, making them much popular in the industry. Consequently 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 by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.
The special tooth root style in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This huge gearing capacity enables smaller tires to be utilized for the comparable torque, and smaller gears with extraordinary power density can also increase reliability. Ever-Vitality geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing perform necessary for troublefree rolling get in touch with to be substantially reduced and therefore the equipment backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are utilized as standard on parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive devices:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
