We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or perhaps without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based with this we can select a wide selection of normal customizations to meet the requirements of various properties that are essential for each application.
If your application requires a gearbox with some special home such as for example small dimensions or low weight with regards to electrical power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, tension 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 start to be able to deliver a product that stands out on your side.
Compact gearboxes are high-top quality gearboxes for standard drives. The electric electric motor is built-in with the gearbox into a single unit (the first equipment is on the electric 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 can not be purchased inside our e-shop. Our professionals will be happy to help you create your selection. We are happy to send out you documentation or style a suitable set directly, on demand.

Ever-Power worm gearboxes possess earned a popularity to be a business benchmark worldwide. Our success came from our relentless travel for quality with state-of-the-art technology, all while offering worm gearboxes will be affordable prices. High versatility accorded through a broad choice of mounting choices, shaft configurations and motor interfaces, would make the Ever-Electrical power worm gearbox the default determination for the market. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Electricity Worm gearboxes provide huge torque with low quickness gear ratio. Being basic and compact in style, these gears can achieve 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 larger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes could be ideal or left-handed dependant on the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key components for low backlash, easily 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, producing them much popular 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 backed simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root style in mixture 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 comparable torque, and smaller sized gears with extraordinary power density also increase reliability. Ever-Ability geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing enjoy required for troublefree rolling get in touch with to be substantially decreased and therefore the equipment backlash to be minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as standard during 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 devices:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
