HT250 uses a Modified Curvilinear Tooth Profile to deliver a clean, compact, cost efficient solution. HT250 drives provide HP ratings 250% greater than conventional HTD drives. Available in 5mm, 8mm, and 14mm metric pitches. These HT Taper-Lock sprockets are built around the Taper-Lock bushing system, allowing you to develop a more compact, cleaner drive. By combining the improved power capacity of the HT belt with the Taper-Lock construction of the HT sprockets, you can achieve maximum power transmission density while minimizing over-hung load.
