A timing pulley is a cogged or cross-tooth pulley with the belt tooth matching the pulley tooth, much like a chain and sprocket. U.S. Rubber developed the first timing pulleys or synchronous pulleys and belts in the 1940s. As the name synchronous implies, timing pulleys were first used to keep two shafts in synchronous. It is in the last 60 years that the timing pulley and belt are considered a positive drive alternative to chain and a replacement for friction drives, such as V-belts.
We at Torque Transmission continue to improve upon this tradition with our time-tested, precise, and reliable timing pulley solutions.
Timing belts offer a broad range of innovative drivetrain solutions; these drives employ the positive engagement of two sets of meshing teeth. Hence, no slippage and almost no backlash, maintaining a constant speed ratio, all extremely important in any application and more so in automated machinery requiring indexing or sequencing.
Timing Pulleys come with many distinct advantages, such as…
Trapezoidal tooth profile with pitch measured in inches.
MXL (0.080), XL (0.200), L (0.500)
Very good positioning accuracy
Curvilinear tooth profile with pitch measured in millimeters.
HTD 3mm, 5mm, 8mm
GT3 2mm, 3mm, 5mm
Higher torque load per centimeter of belt width
Greater positioning accuracy
At Torque Transmission, we understand the importance of precise and reliable power transmission in your systems. All our product’s profiles, widths, and pitch diameters align with MPTA and ARPM Standards.
Together, we can identify your timing pulley needs and then create tailored solutions to meet them.
