Rosta tensioners and the four key advantages of using them

Tensioning devices are available from Rosta.

For 32 years, Rosta Inc. has been supplying innovative industrial technologies for Canadian manufacturers; its global parent company in Switzerland has specialized in these rubber-suspension technologies since the 1940s. The company’s longtime core products include a line of tensioners, or machine components for maintenance-free tensioning of belts and chain drives.

Among the common examples of these tensioner devices are self-adjusting motor-base suspensions (for initial tensioning of large belt drives) and chain and belt tensioners (for efficient secondary tensioning).

Easy installation, long life

Tensioners come in various models to suit virtually all user needs. Rosta tensioning devices offer many significant advantages, from transmission of constant torque to dampening of vibration in belt bands. There are four primary user advantages of investing in Rosta tensioners rather than those of the firm’s competitors:

• Easy installation. To install these tensioners on stiff, even, and clean machine parts, the worker should use a central bolt. The frictional connection on the flange is usually sufficient for final positioning, and the positioning notch can add assurance on the uneven or dirty surfaces by setting a roller pin.
• Long operational life. By handling the belt gently, the tensioner device lowers the level of wear on rollers and bearings, so users benefit from a longer lifespan.
• A variety of options. Rosta tensioners come in seven standard sizes, and they provide a broad range of varying characteristics for different applications. Oil-resistant and heat-resistant options are available, for example, while stainless steel models can assist users in the food-processing and pharmaceutical sectors. Customers can choose from a wide variety of operating temperatures too, running from -40 to 120 degrees Celsius.
• No maintenance required. With Rosta tensioner devices, periodic re-tensioning maintenance is no longer necessary. Tensioners eliminate the compensation of lengthening due to age and belt slip, as well as other common issues.

Many accessories are available to work with these tensioners, such as safety sprockets, pre-tensioning devices, and support brackets. Misalignment can be prevented with double arm tensioners. Trust in Rosta for tensioner devices that serve almost any need that a user may have.
