Feed gear units
Feed gear units to the spn standard
SPN feed gear units are assembly and hand tools with a very high power density. High torques in conjunction with small dimensions and pleasing design make them excellent tools for wide-ranging applications.
Due to the modular system you also have the option to customize your screw spindle to suit your screwing application.
Customer-specific transmission solutions, precise and reliable, are our daily drive.
Basic design of feed gear units
Compared to power gear units, SPN feed gear units transmit significantly higher torques in the same installation space. That means they can handle larger torques in a very small installation space. The gear units are not designed for a defined service life (e.g. 20,000 operating hours) but rather to achieve a defined number of load cycles, depending on the screwing application.
These are the advantages of the SPN feed gear units to the spn standard
- High power density
- Various drive and output versions
- Low-maintenance
- Modular system
- Good adaptation options
