Drive Arrangements and Mounting Positions of Our Tensioning Systems
We offer various tensioning systems for almost every drive arrangement and installation situation. Our response to individual requests: We develop custom models. Tailored in detail to your needs.
Drive arrangement in free space
Chain tensioner with arc profile. Ideal installation situation in empty space just behind the drive wheel. Here combined with sliding rails.
Installation with deflection profile
Spann-Box® with deflection profile, resulting in double the length of the tensioning path, installation situation 1
Installation with deflection profile
Tension-Box® with deflection profile, resulting in double the length of the tensioning path, installation situation 2
Installation with double deflection
Omega tensioning station for demanding tensioning situations with particularly long chain strands. Double deflection.
Side installation
For space constraints below the chain, Spann-Boy® for side mounting.
Reversing operation
Many of our tensioning systems are suitable for reversible operation.
Particularly high temperatures, chemical and corrosion resistance
Our standard version in Original S® green is suitable for use in temperature ranges from -40°C to 60°C. With the right choice of plastic, stainless steel springs and stainless steel housing, temperatures from -40°C to 200°C are possible. By selecting suitable materials for the sliding profile and housing, our Spann-Box® range also offers the option of chemical resistance and corrosion resistance.
THE PERFECT COMBINATION
TENSIONING AND GUIDING
We recommend using guides in combination with a chain tensioner, as this increases the lifespan of the chains. MURTFELDT's chain guides are designed for low-friction movements in systems and machines. They are characterized by high wear resistance and excellent sliding properties.
PRODUCT HIGHLIGHT
Omega Tensioning Station
For precise tensioning of chains in demanding applications, we have developed the Omega Tensioning Station. The automatic chain tensioning system reduces vibrations and extends the lifespan of the chains. It is ideal for long chain drives and reverse operation.
