TENSIONING
BELTS
Tensioning systems for belts make machines more efficient
Belts of all kinds in machines and systems are exposed to high loads. MURTFELDT belt tensioners reliably maintain tension through spring force and ensure maximum operational safety and durability for round, V-, and flat belts, even at high speeds.

The advantages at a glance
- Easy installation
Holes in the housing base, in combination with our mounting brackets, enable quick and secure installation in existing systems
- Flexible installation options
The Spann-Box® and Spann-Boy® can be mounted below the belt, next to the belt, on the long side and front side of the tensioner
- Reduced wear
A smoothly running belt protects the drive elements and extends maintenance intervals for a longer service life of the belts and systems
- Easy retrofitting
Adaptable to existing systems without costly modifications, even in limited installation spaces
Drive arrangements
Lateral installation
The Spann-Boy® TS belt tensioner is the ideal solution for applications with limited installation space, as it is mounted laterally next to the belt. It can be mounted on either the longitudinal or front side of the belt, or used as an idler pulley to ensure optimal belt tension.
Tension roller
The tension roller is made from Original S® black. It is based on UHMW-PE, offers good sliding properties, high wear resistance, is electrostatically dissipative, and ensures a long service life. For special belts, the rollers can be individually customized as needed.
Material usage
The housing of the tensioner is made of steel or, for a corrosion-resistant option, of material.
The high-quality ball bearings are "Made in Germany" and offer particularly long service life.

TANDEM TENSIONER
The Tandem Tensioner ensures consistent belt tension in demanding applications. It is robust and low-maintenance, which results in a long service life and reduced belt wear. Feel free to contact us if needed!
THE PERFECT COMBINATION
TENSIONING AND GUIDING
We recommend using guide rails in combination with a belt tensioner, as this increases the service life of the belts. MURTFELDT belt guides are designed for low-friction motion in systems and machines. They are made from our high-quality Original S® and are suitable for round belts, V-belts, timing belts, and flat belts. Optionally, they are prepared with a corresponding groove for use with a steel C-profile.

Belt Tensioners for Reliable Drive Systems
Proper belt tension is essential for the performance and service life of belt-driven systems. Incorrect tension can lead to increased wear, energy losses, and unplanned downtime. MURTFELDT belt tensioners help ensure reliable belt guidance for round belts, flat belts, and V-belts, supporting smooth and efficient drive operation.
Designed for demanding industrial environments, MURTFELDT belt tensioners combine compact construction, easy installation, and robust performance. They help reduce stress on drive components, lower maintenance requirements, and improve the operational reliability of machinery and equipment.
Whether used in conveying technology, mechanical engineering, or automated production systems, MURTFELDT belt tensioners help maintain consistent belt tension and improve overall drive efficiency. The result is reduced wear, extended service life, and greater productivity across a wide range of industrial applications.
