Bando 400-DS8M-1520 1520 inch long 40 inch wide 7.3 inch high Timing Belt with 190 teeth Synchro-Link Double Sided Timing Belts provide smooth, precise performance under exacting drive conditions in serpentine drives common in printing, textile and packaging machinery. Unique modified curvilinear tooth form enables the STS belt to transmit greater loads than like-sized drives having the standard HTD profile. Smoother tooth engagement and direct contact of belt tooth top with the pulley grooves enables the belt to run quietly even at high speeds. As the tooth meshes with the pulley grooves, the cord lay forms an almost true circle, minimizing the cantilever effect on the cords. Results in reduced bending fatigue and longer service life. No lubrication or re-tensioning required. Higher HP transmission capacity than trapezoidal tooth drives.
