Drive innovation: Rosta’s tensioners deliver four key advantages for maintenance-free tensioning

Rosta makes many tensioner options.

For more than 35 years, Rosta Inc. has been making world-class industrial technologies in Canada – a tradition continued by its parent company in Switzerland for 80 years. The manufacturer’s core product line includes tensioner devices, or machine components for maintenance-free tensioning of chain drives and belts. Common examples of these tensioners include self-adjusting motor-base suspensions, for initial tensioning of large belt drives, in addition to chain and belt tensioners for efficient secondary tensioning.

Various designs for many needs

Tensioners are available in various designs to comply with virtually any user needs. These devices offer several substantial benefits, ranging from transmission of constant torque to dampening of vibration in belt bands. Rosta cites four main advantages of investing in its tensioners instead of alternative solutions from the company’s competitors:

• Simple installation – Tensioners should be installed on stiff, even, and clean machine components with a central bolt. The frictional connection on the flange is typically enough for final positioning, and the positioning notch can add assurance on the dirty or uneven surfaces by setting a roller pin.
• Long operational lifespan – The tensioner device reduces the level of wear on the rollers and bearings with gentle handling of the belt, so users benefit from extended lives of parts.
• No maintenance necessary – Periodic re-tensioning maintenance is no longer required with Rosta tensioner solutions; tensioners eliminate the compensation of lengthening from age to bet slip, in addition to other common issues.
• A variety of options – Rosta tensioners are available in no less than seven sizes, and they offer a wide range of varying characteristics for different applications. Heat-resistant and oil-resistant options are available, for instance, and stainless steel models can help customers in the pharmaceutical and food-processing industries. Businesses can also choose from a broad variety of operating temperatures, from -40 to 120 degrees Celsius.

Rosta also offers accessories that work with these tensioners, such as safety sprockets, pre-tensioning devices, and support brackets. Double arm tensioners can prevent misalignment. For tensioners that can service almost every need that a customer may have, trust the Rosta team.
