We deliver worm gearboxes, spur gearboxes and planetary gearboxes with as well as without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based about this we are able to select a wide selection of standard customizations to meet the requirements of various properties that are important for each application.
If your application takes a gearbox with some special property or home such as small dimensions or low weight in relation to vitality, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of this kind of properties, our item range with more than 1000 different standard gearboxes is most likely an excellent start to have the ability to deliver something that stands out in your favor.
Small gearboxes are high-top quality gearboxes for regular drives. The electric engine is integrated with the gearbox into a single device (the first gear is directly on the electric 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 can not be purchased inside our e-shop. Our specialists will be pleased to help you create your selection. We will be pleased to send out you documentation or style the right set directly, on request.

Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our achievement came from our relentless travel for top quality with state-of-the-artwork technology, all and will be offering worm gearboxes happen to be affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and electric motor interfaces, produces the Ever-Vitality worm gearbox the default decision for the sector. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Ability Worm gearboxes provide excessive torque with low speed gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio than 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 own body is normally quite long in the axial direction. The gears in these gearboxes can be ideal 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 (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 components for low backlash, smoothly running and highly dynamic 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 mounting positions and applications, producing them much sought after in the industry. As a result our geared motors are often 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 supported 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 components used and surface finish maximizes load capacity. This great gearing capacity allows smaller tires to be used for the exact torque, and smaller sized gears with extraordinary power density can also increase reliability. Ever-Electrical power geared motors are consequently incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing perform necessary for troublefree rolling get in touch with to be substantially reduced and therefore the equipment backlash to become minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as standard for 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

Offered in 9 sizes, these worm gearboxes could be supplied with free insight shaft, with hollow bore insight shaft and engine flange, and double decrease mixture units for slow swiftness applications. Employing cast iron housings, top quality bronze alloy worm wheels and long life bearings, reliability and efficiency are the major features of this range.
High Precision Right Position Transmission
Long Lifetime
Wide Selection Of Ratios
Special Surface Treatments
