We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or maybe 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 various properties that are important for each application.
If your application requires a gearbox with some special house such as for example small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, force or temperature, integrated linear screw, or a combination of this kind of properties, our product range with an increase of than 1000 different standard gearboxes is most likely an excellent start to be able to deliver something that stands out on your side.
Compact gearboxes are high-top quality gearboxes for regular drives. The electric engine is built-in with the gearbox into a single device (the first gear is on the motor shaft). Separate gearboxes for connection to conventional IEC motors can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased inside 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 request.

Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our achievement came from our relentless travel for quality with state-of-the-artwork technology, all while offering worm gearboxes will be affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and electric motor interfaces, will make the Ever-Ability worm gearbox the default personal preference for the sector. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Electricity Worm gearboxes provide high torque with low rate gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities are similar to helical gears, but its helix angle is typically comparatively bigger) and its own body is generally quite long in the axial path. The gears in these gearboxes could be best or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or dual), 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 dynamic drive systems.
Our high-performance gear devices are built to withstand the toughest commercial applications.
The apparatus 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 machines.
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 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 excessive gearing capacity enables smaller wheels to be utilized for the same torque, and smaller gears with excellent power density also increase reliability. Ever-Vitality geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play necessary for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to become minimized.
Dual chamber shaft seals produced by Ever-Power are used as standard 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
