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 in this we are able to select a wide selection of common 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 with regards to electricity, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, force or temperature, integrated linear screw, or a combination of such 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 on your side.
Small gearboxes are high-top quality gearboxes for standard drives. The electric engine is included with the gearbox into a single unit (the first equipment is directly on the electric motor shaft). Separate 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 in our e-shop. Our experts will be pleased to help you make your selection. We are happy to send you documentation or design a suitable set directly, on demand.

Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our success came from our relentless drive for level of quality with state-of-the-art technology, all while offering worm gearboxes will 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 personal preference for the market. 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-Electricity Worm gearboxes provide great torque with low quickness 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 qualities are similar to helical gears, but its helix position is typically comparatively larger) and its body is generally quite long in the axial direction. The gears in these gearboxes could be best or left-handed dependant on the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Vitality gearboxes and geared motors will be the electro-mechanical key components for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear systems are designed to withstand the toughest industrial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, making them much popular in the industry. Consequently 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 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 huge gearing capacity enables smaller tires to be utilized for the exact torque, and smaller gears with outstanding power density also increase reliability. Ever-Electrical power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play necessary for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are utilized as standard through parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive devices:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
