FHT Class of Synchronous Belts

March 27, 2008
Fenner Precision, a leader in belts, tires and pulleys, now offers the Fenner High Torque (FHT) Class of synchronous belts which are made of polyurethane.  The nature of polyurethane offers several advantages over traditional materials including a cleaner tooth profile, different grades for higher COF and temperatures, and tensile strengths exceeding 1,000 pounds.The FHT Class of belts is available in various sizes and pitches including 1mm, 2mm, 3mm and 5mm.  The FHT belts have a curvilinear tooth profile as opposed to the traditional trapezoidal profile.  The curvilinear profile offers two outstanding and distinct benefits: more surface contact with the pulley and more uniformly distributed stress concentration.  Other benefits of this profile include:  less noise, dusting, backlash and vibration; improved positioning; better wear, accuracy, and meshing with the pulley.The FHT Class of belts is available open ended as well as truly endless.The Fenner Precision engineering staff will work with clients to customize the FHT belts to meet their unique design situation.  Solutions can include tooth pitch adjusted to match stepper motor pulse rates, miniaturization of overall design, integral molded features, and custom reinforcements among other various unique custom features according to needs.  Fenner Precision can also engineer backside customization such as lugs, cleats and fastening points.While the FHT Class of belts are conducive to paper propulsion applications such as office scanners, faxes, copiers, printers, binding machines, collators and folders, the belts are also useful in medical, electronic, closed-circuit TV, camera, ATM and toy applications.
