Our pulleys can be used for application with a speed up to 35m/s. The pulley dimensions are very accurate as they are manufactured only by means of CNC or automatic lathes. For higher speed is strongly recomended to use steel as material of construction.
Our PBT pulleys are statically balanced according to ISO.
The PT pulleys are not balanced, as they do not have a finished bores.
SITEX® gear couplings consist of two toothed hubs which are connected with one internally toothed sleeve. The hubs are made of steel and the teeth, which are both profiled and section crowned, are obtained from milling. The sleeve is manufactured from stabilized 6.6 superpolymade resin.
HTD pulleys have a different design from the traditional toothed pulleys. The axial grooves are designed to allow the beltteeth to catch the pulley teeth with negligible triction. HTD Pulleys are available with full hub and for assembly with SER-SIT taper bushing.
