FLEX COUPLINGS
FLEX COUPLINGS
FLEX COUPLINGS

BAUMANN FLEX COUPLINGS ARE CONNECTION ELEMENTS THAT ARE INDEPENDENT OF THE DIRECTION OF ROTATION AND ARE CHARACTERIZED BY AN EXTREMELY LONG SERVICE LIFE.
 
The radially, axially and angularly flexible products can be used up to a torque of 900 Nm. All components are made of steel.

The BAUMANN Flex couplings are temperature resistant from -40°C to +100°C in the standard version. For special applications couplings for temperatures up to + 300°C are also available. The standard range includes couplings for torques from 2.5 to 900 Nm.

Depending on the design, the spring bodies are connected with sleeves, flanges or hubs. All designs are available in three different lengths. All sizes are available from stock in various predrilled versions. On request, customer-specific bores, keyways, threaded bores, etc. can be made for you.
