Precision Gears Performance in Accuracy Your addition in transmission.
The foundations were laid over 100 years ago: In the small mill belonging to the Stephan family in the 1890s, everything already centered around the perfect drive system. And this is how it has remained though we have of course grown in the meantime. Premium Stephan: Innovative and reliable Today we offer a wide range of products in the field of gear units and geared motors. This enables us to offer our customers tailored solutions at any time, from a standard gear unit, through products adapted for specific applications, to custom-made gear units. Precision gearbox compact series MELIOR MOTION With almost 30 years experience in the development and production of highly precise, backlash-free customised gearboxes, Premium Stephan is a leading supplier to the robotic industry. The new MELIOR MOTION range is another exciting innovation from Premium Stephan, specifically designed for use in robots, medical devices, machine tools and many other types of automation equipment.

Product highlights The need of highly precise gearboxes in machinery and plant engineering is steadily increasing. The main requirements are for low backlash and high torques, considering at the same time optimal values in terms of tilting and torsion stiffness in a very compact design. Premium Stephan does not only offer a new standard precision product range, but is also able to make adaptions and special solutions, to meet your request. The impressive knowhow in design and production of the Premium Stephan engineers is based on an experience of more than a quarter-century in the development of special precision gearboxes for individual, customized requirements in the automation industry. The product range can be supplied as sub-assemblies which can be directly mounted into your application. Alternatively we offer enclosed gearbox designs and Geared Motors, which are supplied for use with standard mineral oils. All sizes are available as full shaft versions (execution -V) or hollow shaft version (execution -H), with hollow shafts up to 73 mm diameter, allowing a feed-through of cables.

Customized Precision Gearboxes Our Customized Precision Gears dispose of a backlash smaller than 0.1 arcmin and can therefore be described as backlash-free. The accuracy in positioning of +/- 0.03 mm is achievable throughout the very long lifetime of the gearbox, thanks to the special constructional design. Your addition: Individually configurable concerning housing design and adaption of the servo motor to your specifications Long-lasting even under the toughest working conditions Adaptable to customer-specific requirements and dimensions thanks to various possibilities of solution Powerful due to the use of high load-bearing components Uniquely high efficiency in the market Very low energy demand Maintenance free thanks to optimal constructional design Low-noise due to optimal gearing geometry Features Advantages Flexible concept of assembly based on a modular system. Optimized gearing geometry and precise grinding create a smooth rolling of the tooth flanks involved in the engagement. Premium-Stephan self-adjusting gear technology. Lubrication with special and food grade oil possible. High quality sealings at input and output shaft. Hollow shafts up to a diameter of 95 mm. Diverse rigid housing options. High resistance due to use of highest quality components. Production under favorable and competitive conditions. The result is a perfect tooth engagement, even load distribution across the complete face width, minimum vibrations and therefore a smooth, low-noise operation. This ensures there is no deterioration in backlash throughout the very long lifetime. Operation also in medical technology and food industry. Suitability for super clean room applications. Easy realization of feedthrough of cables or other media. Guarantees maximum resistance under high load and trouble-free operation. Applicable even under the toughest working conditions, e.g. at welding.
