Rosta tensioners offer various user benefits.

Rosta Inc. has been supplying innovative industrial technologies for Canadian businesses for more than three decades – a tradition carried on by its parent company in Switzerland for more than three-quarters of a century. The company’s core product line includes tensioner solutions, or machine elements for maintenance-free tensioning of chain drives and belts. Some common examples are self-adjusting motor-base suspensions, for initial tensioning of large belt drives, and chain and belt tensioners, for efficient secondary tensioning.

Transmission of constant torque

Tensioners come in different models to suit virtually any user requirement. Rosta tensioning devices offer several significant benefits, from transmission of constant torque to dampening of vibration in belt bands.

The four primary user advantages of investing in Rosta tensioner solutions instead of those of the company’s competition:

  • Easy installation – The worker should use a central bolt to install these tensioner devices on stiff, even, and clean machine parts. 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 – By handling the belt gently, the tensioner reduces the level of wear on rollers and bearings, so users benefit from longer component lives.
  • No maintenance necessary – Periodic re-tensioning maintenance is no longer required with Rosta tensioners. Tensioners eliminate the compensation of lengthening from age and belt slip, in addition to other frequent problems.
  • A variety of options – Rosta tensioners come in seven standard sizes, and they offer a wide range of different characteristics for varying applications. For instance, heat-resistant and oil-resistant options are available, while stainless steel models can assist users in the pharmaceutical and food-processing industries. Users can also choose from a broad spectrum of operating temperatures, running from -40 to 120 degrees Celsius.

Rosta also offers many accessories to work with these tensioners, including safety sprockets, pre-tensioning devices, and support brackets. Double arm tensioners cam prevent misalignment.

Rely on Rosta for tensioners that can serve virtually any need that a user may have.
