The TS (Torlon System) Invert Pulley is the top the of the range - as used in all Roisub spearguns! If you want to convert or build the absolute ultimate in invert roller spearguns, these are the pulleys to use. Price is for single Invert Pulley with Torlon bearings.
TS pulleys are the heart of the Roisub System. Made by special dedicated machines in a controlled environment and designed to work with heavy loads, using large diameter torlon balls and each sphere with an 812 kg breaking load. Torlon has the highest wear resistance compared to delrin or other plastic material and has the lowest coefficient of friction. These features ensure the maximum speed possible with high workloads.
These are the best pulleys and bearings for high speed, high load, high performance, particularly the de-multiplied invert pulley systems.
Built with Delrin shell and Torlon ball bearings, these pulleys have tolerances greater than ever before. The unique egg shaped bearings, designed by Roisub, further reduce friction on the side walls.
This product is a real jewel of technology, designed to the highest quality and refinement, to obtain incomparable performance, even with high loads.
