120t x 9mm Wide Timing Belt (HTD 5mm)
Synchronous timing belts require no tension adjustments, are lighter, and have a higher level of efficiency than chain. The 5mm HTD profile is perfect for FIRST ® Robotics Competition applications - its deep tooth profile allows it to better handle high reversing loads, such as those found in an FIRST ® Robotics Competition drivetrain.
VEXpro belts are fabricated using industry leading timing belt methods. The neoprene body insulates against grease or other wear & tear, and fiberglass tensile cords provide increased strength, flex life, and resistance to elongation.
