Stober

Stöber Antriebstechnik is a leading German manufacturer of high-precision gearboxes, servo motors, drive amplifiers, and complete motion control systems for industrial automation. With over 75 years of experience in precision drive technology, Stöber delivers solutions for the most demanding positioning and motion tasks in manufacturing, robotics, and packaging technology.

The core Stöber range includes helical gearboxes, right-angle gearboxes, bevel gearboxes, planetary gearboxes, and worm gear reducers in high-efficiency, minimal-backlash versions. Gearboxes are available with hollow shaft, solid shaft, and flange outputs, and are compatible with all common servo motors from Siemens, Bosch Rexroth, Beckhoff, and other manufacturers.

The Stöber POSIDRIVE FDS 5000 and MDS 5000 drive amplifiers are advanced servo inverters with integrated STO (Safe Torque Off) safety function, multi-encoder interface, and built-in motion controller. They support protocols including EtherCAT, PROFINET, CANopen, and EtherNet/IP for seamless integration into modern automation systems.

Stöber servo motors in the EZ-series are specifically designed for use with Stöber gearboxes and offer optimal torque density, low inertia, and precise encoder resolution (up to 23-bit single/multi-turn). The gearbox-motor combination is supplied as a single optimized system, greatly simplifying commissioning time and parameterization.

At Verkopershulp.nl we carry over 7,183 genuine Stöber parts, including gearboxes, motors, drive amplifiers, encoders, and accessories. As an authorized distributor we guarantee fast delivery, technical support for selection and commissioning, and full warranty on all Stöber products.

History

Stöber Antriebstechnik was founded in 1934 in Pforzheim, Germany by Karl Stöber. The company began manufacturing precision gears for the jewelry industry of the Pforzheim region. In the 1950s Stöber expanded into industrial reducers and became a specialist in wear-resistant gearboxes for the manufacturing industry. In the 1980s and 1990s Stöber invested heavily in servo technology and developed its own servo drive systems and motors. The introduction of the POSIDRIVE drive series in the 1990s established Stöber's reputation as a manufacturer of complete motion control systems. The company remained a family business and grew organically through continuous product innovation. Today Stöber has its headquarters and manufacturing in Pforzheim with offices in Europe, North America, and Asia. The company supplies its products in over 50 countries and is known for exceptional technical service and application support. Stöber is ISO 9001 certified and invests significantly each year in R&D for the next generation of drive technology.

Frequently Asked Questions

How do I select the correct Stöber gearbox for my servo motor? ▾
The choice depends on the required gear ratio, output torque, input speed, mounting position, and motor flange. Stöber provides comprehensive selection tools and configuration software (STÖBER Drive) that calculate the optimal gearbox based on your load profile, cycle frequency, and required positioning accuracy.
Which communication protocols do Stöber POSIDRIVE drive amplifiers support? ▾
Stöber POSIDRIVE FDS 5000 and MDS 5000 drive amplifiers support EtherCAT, PROFINET, CANopen, DeviceNet, and EtherNet/IP. This makes them compatible with all common PLC and robot controllers from Siemens, Beckhoff, Bosch Rexroth, Mitsubishi, and other manufacturers. The integrated STO safety function meets SIL2/PLd requirements.
Are Stöber gearboxes compatible with motors from other brands? ▾
Yes, Stöber gearboxes are available with standardized IEC flange bores and shaft adapters compatible with motors from Siemens, ABB, SEW-Eurodrive, and other manufacturers. Stöber supplies specific adapter sets for most popular motor models. Use the Stöber motor matching guide for correct coupling.
What is the backlash of Stöber planetary gearboxes? ▾
Stöber planetary gearboxes are available in standard (backlash < 10 arcmin), precision (< 5 arcmin), and high-precision (< 3 arcmin or less) versions. For positioning applications requiring high repeatability, the precision or high-precision variants are recommended. Always specify the required backlash in your inquiry.
What is the IP protection rating of Stöber gearboxes? ▾
Standard Stöber gearboxes have an IP65 protection rating (dust-tight and splash-proof). IP66 or IP69K (high-pressure wash-down resistant) versions are available for the food and beverage industry where frequent cleaning with high-pressure jets is required. Stainless steel and food-safe lubricants are optionally available.
How long do Stöber gearboxes last? ▾
Stöber gearboxes are designed for a nominal service life of L10h = 20,000 operating hours or more at nominal load. Actual service life depends strongly on the load factor, lubrication, and environmental conditions. Correct lubrication with the recommended oil or grease is the most important factor for a long gearbox service life.
Does Verkopershulp.nl supply overhaul kits for Stöber gearboxes? ▾
Yes, we supply genuine Stöber overhaul kits with bearings, seals, gaskets, and lubricants for all common Stöber gearbox models. A timely overhaul significantly extends service life and prevents costly downtime. Specify the model number and serial number of your gearbox for the correct overhaul kit.
What is the efficiency of Stöber gearboxes? ▾
Stöber helical and planetary gearboxes achieve a mechanical efficiency of 96-98% per stage, thanks to precision-ground gears and high-quality lubrication. This results in minimal heat generation and energy losses, important for compact servo drives with high cycle frequency in the packaging and robotics industries.
