# ZK Bevel gearboxes | Technology that gets it right

The ZK Series is designed for a service life of over 20,000 operating hours. The stable grey cast-iron housing in RAL 7021, paint-free sealing elements and shafts ensure a precise fit. Special coatings and customer-specific versions with additional paint-free areas at various connection interfaces are available on request.

ZK Bevel gearboxes are available with ratios 1:1, 2:1 and 3:1; further variants are in development. Proven lubrication reduces maintenance effort.
