Imperial Pitch Belts - XL, L, H, XH
This classic trapezoidal pitch is the original timing belt tooth design. This tooth pitchis commonly used for conveying applications. The tooth profile is fairly low and has a large surface area at the tip of the tooth providing good support on sliding conveyor surfaces.
T Pitch Belts - T2.5, T5, T10, T20
These metric trapezoidal pitches are similar to imperial pitches, also commonly usedfor conveying applications, yet have a slightly deeper tooth engagement than imperial profiles. The tooth meshing is more reliable. However, backlash can be slightly greater.
AT Pitch Belts - AT5, AT10, AT20
This pitch was developed to enable higher load carrying capacity combined with lowbacklash. The stronger and stiffer tooth makes these belts ideal for linear positioningand motion control, but may require larger pulley diameters.
STD Pitch Belts - STD5, STD8
This tooth pitch provides superior load distribution, low backlash, and reduced wearand noise characteristics. It is an excellent profile for linear positioning and power trans-mission applications.
HTD Pitch Belts - HTD5, HTD8, HTD14
This rounded tooth pitch is similar to STD, and is also an excellent profile for linearand rotary positioning and power transmission applications, yet has deeper toothengagement. Note that the HTD pitch may exhibit slight increases in noise and wear.

Gates Mectrol manufactures linear
timing belts in a variety of tooth
pitch, length, and material combi-
nations. This offering provides a
wide range of possible configura-
tions for your application.
Linear belt lengths are available
in two styles welded endless
and open ended. Welded endless
belts are ideal for low torque
conveying applications. Open
ended belts are typically used for
motion control applications.
Endless belts of virtually any length can beproduced utilizing a thermal welding processwhich joins the ends of the belt together.
Features
Very high tensile strength and stiffness
Parallel cord construction- No cords exposed at belt edges- Better tracking- Uniform tensioning
Tough polyurethane construction- Durable and cut resistant- Oil, chemical and water resistant- Non-marking
Steel or Kevlar tension members
Choice of polymers including FDA grades
Nylon back and nylon tooth surfaceoptions available for quieter operationand reduced friction
