We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or perhaps without integrated linear lead screw / ball screw adapted to your flexible modular concept.
Based on this we are able to select a wide variety of common customizations to meet up the requirements of varied properties that are important for each application.
If your application takes a gearbox with some special home such as for example small dimensions or low weight in relation to vitality, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of this kind of properties, our item range with an increase of than 1000 different standard gearboxes is probably a good start to be able to deliver a product that stands out in your favor.
Small gearboxes are high-quality gearboxes for standard drives. The electric electric motor is included with the gearbox right into a single unit (the first gear is directly on the motor shaft). Individual gearboxes for connection to 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 happy to help you make your selection. We are pleased to send you documentation or design the right set directly, on demand.

Ever-Power worm gearboxes possess earned a status to be a business benchmark worldwide. Our success originated from our relentless drive for level of quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and engine interfaces, will make the Ever-Ability worm gearbox the default personal preference 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-Ability Worm gearboxes provide huge torque with low velocity 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 are similar to helical gears, but its helix position is typically comparatively bigger) and its body is normally quite long in the axial direction. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Electrical power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, easily running and highly powerful drive systems.
Our high-performance gear devices are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, producing them much sought after 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 backed by FEM (Finite Element Method). This tooth geometry ensures 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 great gearing capacity enables smaller wheels to be used for the equal torque, and smaller sized gears with exceptional power density can also increase reliability. Ever-Vitality geared motors are consequently incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform necessary for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to become minimized.
Double chamber shaft seals produced by Ever-Power are used as standard for parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
Precision Worm Gearboxes and also Geared Motors
