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 at this we are able to select a wide selection of ordinary customizations to meet up the requirements of varied 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 electrical 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 such properties, our item range with more than 1000 different standard gearboxes is probably an excellent start to be able to deliver something that stands out on your side.
Small gearboxes are high-top quality gearboxes for standard drives. The electric electric motor is included with the gearbox into a single device (the first gear is on the electric motor shaft). Individual gearboxes for link with conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our specialists will be pleased to help you create your selection. We will be happy to send you documentation or style the right set directly, on demand.

Ever-Power worm gearboxes possess earned a status to be a business benchmark worldwide. Our success originated from our relentless travel for level of quality with state-of-the-artwork technology, all and will be offering worm gearboxes will be affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and motor interfaces, produces the Ever-Electricity worm gearbox the default choice 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-Ability Worm gearboxes provide great torque with low acceleration 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 body is generally quite lengthy in the axial path. The gears in these gearboxes could be best or left-handed depending upon the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Vitality gearboxes and geared motors are the electro-mechanical key elements for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear devices are built to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse installation 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 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 design in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This huge gearing capacity enables smaller wheels to be utilized for the exact torque, and smaller sized gears with excellent power density also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing enjoy required for troublefree rolling contact to be substantially reduced and therefore the gear backlash to end up being minimized.
Dual chamber shaft seals developed by Ever-Power are utilized as standard for parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
