Fenner Drives 405050 Powertwist Drive Ribbed Link Belt B/17/5L Section 5/8 Inch Wide 25 Ft

Product Description

The Fenner Drives 405050 PowerTwist Drive Ribbed Link Belt is a flexible, field-serviceable V-belt solution designed for industrial and commercial drive applications. Built in the B/17/5L section size, this belt measures 5/8 inches in top width, 5/8 inches in thickness, and comes in a 25-foot outside length, giving technicians and maintenance professionals plenty of material to cut custom lengths on the job without downtime. The PowerTwist link belt design is one of the most practical alternatives to traditional endless V-belts. Unlike standard belts that require motor repositioning or pulley disassembly to install, this ribbed link belt can be threaded onto a drive system without disturbing the motor mount or shaft alignment. Individual links connect and disconnect by hand, making installation and replacement fast on conveyors, fans, compressors, pumps, and other belt-driven equipment. The belt is constructed from a polyester and polyurethane composite, which delivers strong tensile performance, resistance to oil and chemicals, and a wide operating temperature range of -40 to 240 degrees Fahrenheit. This temperature tolerance makes the 405050 suitable for both cold storage environments and high-heat mechanical rooms. The red color provides easy visual identification on multi-belt drive systems. With a minimum pulley diameter of 5 inches, this belt is compatible with a wide range of standard sheaves used in HVAC, agricultural, manufacturing, and general industrial settings. The single-rib, single-band configuration matches B-section drive profiles, making it a direct fit for systems designed around standard B-type or 5L or 17-series belt geometries. Maintenance crews, millwrights, and HVAC technicians keep PowerTwist link belts on hand as a reliable emergency replacement and a permanent drive solution. The 25-foot roll provides enough length for multiple cuts across different belt lengths in the B/17/5L section range.

• Field-installable link belt design allows replacement without moving the motor or disassembling the drive
• Polyester/polyurethane construction resists oil, chemicals, and temperature extremes from -40 to 240 degrees Fahrenheit
• B/17/5L section size with 5/8 inch top width fits standard B-section sheaves with a minimum 5 inch pulley diameter
