tensioner devices

Rosta tensioning systems offer many significant user benefits.

Rosta has been an international force in rubber suspension technology for more than three-quarters of a century, and Rosta Inc. has brought the company’s innovations to Canada for three decades. One of Rosta’s core products has always been tensioner devices, or machine components for maintenance-free tensioning of belts and chain drives.

Rosta tensioner devices come in many varieties to suit virtually any industrial need. From self-adjusting motorbase suspensions for initial tensioning of large belt drives to chain and belt tensioners for efficient secondary tensioning, Rosta can get the job done.

Easy installation and long life

Customer benefits from using Rosta tensioning devices are multifold, from transmission of constant torque to dampening of vibration in belt bands. The company identifies four primary advantages of choosing Rosta over its competitors for these products:

  • Easy installation. Rosta advises users to install tensioners on stiff, even, and clean machine parts by using a central bolt. Usually, the frictional connection on the flange is sufficient for final positioning, and the positioning notch can add assurance on uneven or dirty surfaces by setting a roller pin.
  • No maintenance. With Rosta tensioning systems, periodical re-tensioning maintenance becomes unnecessary. This is because these devices eliminate the compensation of lengthening due to age and belt slip, among other common problems.
  • Long service life. The unit’s gentle handling of the belt decreases the amount of wear on rollers and bearings, resulting in longer operational life.
  • A variety of options. Available in seven standard sizes, Rosta tensioner devices have a wide range of different characteristics for different applications. Clients can get oil-resistant and heat-resistant options, and stainless steel versions are useful in the food-processing and pharmaceutical sectors. These tensioners also come in a variety of operating temperatures, ranging from -40 to 120 degrees Celsius.

Rosta tensioning systems are also available with many accessories, such as safety sprockets, pre-tensioning devices, and support brackets, while double arm tensioners can help users avoid misalignment.

For tensioners that can serve just about any application a company may have, Rosta Inc. is the best place to go.
