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 upon this we are able to select a wide variety of standard customizations to meet the requirements of varied properties that are important for each application.
If your application requires a gearbox with some special real estate such as small dimensions or low weight with regards 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 mixture of this kind of properties, our product range with an increase of than 1000 different standard gearboxes is most likely a good begin to have the ability to deliver something that stands out in your favor.
Small gearboxes are high-quality gearboxes for standard drives. The electric engine is included with the gearbox right into a single device (the first gear is directly on the motor shaft). Separate gearboxes for connection to conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our experts will be pleased to help you make your selection. We will be happy to send you documentation or design the right set directly, on demand.

Ever-Power worm gearboxes have earned a reputation to be a business benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the sector. The helical-worm and the Compact Worm Gearbox 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 velocity gear ratio. Being simple and compact in design, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix position is typically comparatively bigger) and its body is generally quite lengthy in the axial path. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-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 units are designed to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and invite diverse installation positions and applications, producing them much sought after in the industry. As a result 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 get in touch with 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 high gearing capacity enables smaller tires to be used for the same torque, and smaller sized gears with remarkable power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing perform necessary for troublefree rolling contact to be substantially reduced and then the gear backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are used as regular in 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 systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
