As an international success story for more than 75 years, Rosta and its Canadian affiliate, Rosta Inc., keep industry operational and productive with their mastery of tensioning technology.

Four types of accessories available

Rosta supplies complementary accessories for tensioning to suit any need, even for customers who intend to use chain riders. Examples include a mounting bracket as a flexible and practical means of fixing and implementing Rosta tensioners in construction applications, for one. Do-it-yourself is never required, and tensioning accessories are available to support any critical component that Rosta provides.

The four main types of accessories for tensioning from which to choose:

• Sprocket wheel set, Type N. For completing the tensioning elements in chain-drive applications. Each sprocket wheel runs on a self-lubricating ball bearing 2Z.X3. Simplex, duplex, and triplex sets are available in various sizes. Wheels contain 11, 13, or 15 teeth, and weight ranges from 60 grams (g) to 1.93 kilograms (kg).
• Chain rider set, Type P. Inexpensive low-noise alternative for tensioning chain drives, assembled on the tensioning element. Built from fiction-resistant industrial plastic, the high-quality rider allows use on both rider sides. The highest permissible chain speed is 1½ metres a second.
• Tensioning roller, Type R. Made out of high-quality industrial plastic material, with two self-lubricating ball bearings 2Z.C3. Rosta offers five sizes with maximum speeds from 4,500 to 8,000 revolutions per minute (RPM), maximum belt widths from 30 to 130, and weight from 80 g to 1¾ kg.
• Tensioning roller, Type RL. Similar to Type R, but constructed for light-duty drives. Rosta supplies three sizes, with maximum speeds from 4,500 to 8,000 RPM, maximum belt widths from 30 to 55, and weight from 80 to 500 g.

Other units are available for different needs.
