We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based upon this we are able to select a wide selection of standard customizations to meet the requirements of varied 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 in relation to power, high efficiency, quiet and vibration-free operation, extended life, high resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our product range with more than 1000 different standard gearboxes is probably a good start to be able to deliver something that stands out in your favor.
Compact gearboxes are high-quality gearboxes for regular drives. The electric motor is built-in with the gearbox into a single device (the first gear is on the electric motor shaft). Separate gearboxes for connection to conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our experts will be happy to help you make your selection. We will be happy to send you documentation or style the right set directly, on request.

Special wishes possible
Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a broad choice of mounting choices, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the sector. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low rate gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction 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 path. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key components for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear devices are built to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, producing them much popular in the industry. Because of this our geared motors tend to be to be found within 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 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 high gearing capacity allows 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 therefore incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing enjoy necessary for troublefree rolling contact to be substantially decreased and therefore the gear backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are utilized as regular in parallel shaft, shaft mounted and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
