Timing belt pulleys

For HTD 8M toothed pulleys with a brake width of 50 mm, we offer clamping bushings, so-called Taperlock (TB) bushings, which serve as a locking mechanism for securing the pulley. 8M refers to the tooth pitch, which expresses the distance in millimeters from the center of one tooth to the center of the next. HTD 8M toothed belt pulleys with a brake width of 50 mm accommodate TB numbers from 1108 to 3020, with shaft bores from Ø28 to Ø75.  

Profile: HTD, Tooth pitch: 8 mm, Brake width: 50 mm, Number of teeth: 28-192, Shaft diameter: 28-75 mm, Taperlock (TB) numbers: 1108-3020, Material: Fine grain cast iron GG20.

HTD stands for High Torque Drive and is a standard pulley compatible with HTD and RPP timing belts. HTD timing belts are also available in reinforced versions with two or four times the tensile strength, ensuring greater efficiency and precision. HTD pulleys are used in machine tools, the paper industry, and the textile industry, where long service life and minimal maintenance are essential. All HTD timing belt pulleys comply with REACH and RoHS directives.

During installation, clean the surface and insert the bushing into the drive element. Loosely insert the screws into the threaded holes and place the drive element onto the shaft. Tighten the screws alternately using an Allen wrench. Check the tension after a short operating time.
