Endless belts refer to closed loops. Open-ended belting are lengths of belt that may be connected. Adjustable-length belting may be assembled to variety of lengths. Endless Belts | Open-Ended Belting Timing Belt Series A timing belt series is an industry standard designation that includes belts for a given set of width, pitches, and tooth style. AT10 Series | B Series | G Series | H Series | HPPD Series | HTD Series | L Series | MXL Series | Poly Chain GT Series | Power Grip GT Series | W Series | XL Series | Y Series Belt Construction Single-Sided with Trapezoidal Teeth: Trapezoidal tooth design eliminates the slippage associated with V-belts, and the noise and lubrication problems of metal roller chain. Single-Sided with Curved Teeth: The curved tooth profile results in more surface area contact between these belts and pulleys, providing higher torque capacity, a stronger grip, and quieter operation. Interchangeable with HTD (high torque drive), Power Grip GT, and HPPD (high performance power drive) synchronous drive belts and pulleys. Double-Sided with Trapezoidal Teeth: Double-sided for simulateous use on two or more shafts. Trapezoidal teeth mate with grooves in timing belt pulleys for a positive grip. Either side can transmit a full load; serpentine them to transfer full power on both sides. Single-Sided with Tire Track Teeth: Here's an extremely quiet belt and pulley system for your high-torque, high-precision operations. The unique tire-track tooth profile of the belts (also known as the eagle design) results in optimum surface area contact with the pulley for ver low noise and superb grip. The tire-track design also makes the belts self-tracking, so there's no need for flanges on the pulleys--this gives you a drive that takes up less space, weighs less, and puts less load on your bearings. Double-Sided Flexi-Timing: The special tooth-design of these flexible synchronizing belts allows slight to significant misalignment between multiple pulleys in a drive. Belts are double-sided, so they can be serpentined. Material Rubber The industry standard for belt materials. Durable, flexible, and is able to absorb heat that is produced as the belt moves through the pulley. Silicone Rubber Stand up to high temperatures, corrosion, and chemical contact. Molded Polyurethane Offers resistance to tearing and abrasion, as well as good resistance to oils, water, and chemicals. Urethane Will not mark surfaces the way that other materials do. Run more quietly than comparable rubber belts, while providing the same durability and flexibility. High resistance to abrasion, oil, and chemicals. Designed for light-duty power transmission applications. Belt Width 1/8" | 3/16" | .20" | .22" | 1/4" | 5/16" | 3/8" | 1/2" | 3/4" | 1" | 1-1/2" | 2" | 12 mm | 15 mm | 16 mm | 20 mm | 21 mm | 25 mm | 30 mm | 32 mm | 35 mm | 36 mm | 37 mm | 40 mm | 50 mm | 52.5 mm | 55 mm Pitch The pitch of a timing belt is the distance between the center of the crown of one tooth and the center of the crown of the tooth next to it. .08" | .157" | .2" | .375" | .5" | 5 mm | 8 mm | 10 mm | 14 mm Color Black | Off-White | Translucent Yellow http://www.mcmaster.com/ I added a link but this page gives a small picture of what is available.
