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 on this we are able to select a wide selection of regular customizations to meet the requirements of various properties that are essential 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 power, high efficiency, quiet and vibration-free operation, extended life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our product range with an increase of than 1000 different standard gearboxes is most likely a good begin to be able to deliver something that stands out on your side.
Compact gearboxes are high-quality gearboxes for regular drives. The electric engine is built-in with the gearbox into a single unit (the first gear is directly on the motor shaft). Individual gearboxes for link with 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 specialists will be happy to help you make your selection. We will be happy to send out you documentation or style the right set directly, on ask for.

Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our success originated 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 choices, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. 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-Power Worm gearboxes provide high torque with low speed gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively bigger) and its own body is generally quite lengthy in the axial direction. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or dual), 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 powerful drive systems.
Our high-performance gear models are designed to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, making 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 backed simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling get in touch with 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 high gearing capacity enables smaller wheels to be utilized for the same torque, and smaller gears with excellent power density can also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play required 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 utilized as standard in parallel shaft, shaft installed 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
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
