Description
Key features:
Due to an increasing demand for gearboxes that can handle more precise movements, we have developed precision gearboxes. The technology is based on the high qualities that generally characterize worm gearboxes. In addition to the special design, production and assembly methods, the gearboxes meet strict precision requirements. On request, we can prove backlash, tolerances, etc. by means of measurement reports
Clearance values include all clearances for bearings and gears, as well as tolerances for keys and keyways, bearing seats, etc. The backlash values do not include elastic and static deformations due to the loads to which the gearbox is subjected. Contact our specialists for more information.
- ATEX certification: Our standard worm gear products are supplied for zones 2 and 22 according to the ATEX directive. Products for zones 1 and 21 can be supplied according to the task
- Custom gear ratios: Available in a range of gear ratios from 5.4:1 to 75:1. Other ranges are available on request
- Oil and lubricants: We have a wide range of oil/lubricants for different operating temperatures and for special environments. The gearboxes are lifetime lubricated with fully synthetic oil as standard
- Gear size: We offer gearboxes with center distances from 42 to 99 mm and with output torques from 10 to 891 Nm
- Output shaft material: Our output shafts are made of SS1672-08 as standard. Other materials are possible
- Drive side: For D-side mounting, we offer motor flanges, coupling housings or end covers for other power inlet connections. Customizations are possible
