Do-it-yourself is never necessary

Complementary accessories are available for tensioning to suit any requirement, even for clients who intend to use chain riders. Among the examples are a mounting bracket as a flexible and practical means of fixing and implementing Rosta tensioners in construction tasks. Do-it-yourself is never necessary, and tensioning accessories are available to support any critical component that Rosta supplies.

The four kinds of tensioning accessories that are available from Rosta:

• 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 different 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. Made from fiction-resistant industrial plastic, the high-quality rider enables use on both rider sides. The highest permissible chain speed is 1½ metres per second.
• Tensioning roller, Type R – built out of high-quality industrial plastic material, with two self-lubricating ball bearings 2Z.C3. Rosta supplies 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.
