Rosta tensioning technology produces motor bases and tensioner devices

Motor bases are among Rosta's tensioning products.

In 32 years of supplying essential machine elements in Canada – with a parent corporation that has been doing so worldwide for nearly eight decades – Rosta Inc. has distinguished itself as a master of three types of technology: rubber-suspension, oscillating-conveyor, and tensioning technology. With the third capability, the company manufactures an impressive array of tensioner devices, motor bases, and accessories. This has always been one of Rosta’s core competences.

Always a perfect solution available

Rosta takes pride in its expertise in tensioning products – made through the concept and production of machine components for the maintenance-free tensioning of belt and chain drives. There is always a perfect solution available, whether for the initial tensioning of large belt drives with Rosta’s own self-adjusting motor-base suspension or for efficient secondary tensioning by means of easy-to-install chain and belt tensioners.

A primary advantage of using Rosta tensioning systems is the elimination of many common issues in machine design, such as the compensation of lengthening due to age and belt slip. With Rosta tensioning technology, the user no longer has to worry about periodical re-tensioning maintenance.

Rosta’s tensioning technology produces the following three kinds of products:

• Tensioner devices. Self-adjusting, maintenance-free tensioning systems to make up for length compensation and slippage. These devices offer the lowest damping factor on the market, resulting in significantly longer chain, belt, and pulley life and minimal downtime.
• Motor bases. Each Rosta motor base is a two-in-one system: a motor support with an integrated self-tensioning system, which always maintains the perfect belt tension for constant transmission of the nominal torque. The result is an extended belt and pulley lifetime and substantial energy savings.
• Accessories. Rosta offers sprockets, chain riders, and rollers to work with these tensioning units. Whatever chain or belt drive a customer has, the ideal sprocket or roller is available; there are even complementary accessories for chain riders. Do-it-yourself is never required; a mounting bracket offers the most flexible and practical way to fix and implement a Rosta tensioner.

For machine elements that keep manufacturers productive, the name to trust is Rosta.
