Pulley TS (Torlon System) ROIsub

ROO58

New

TS pulleys are the heart of the Systems Roisub. Realized by special dedicated machines in a controlled environment and designed to work with heavy loads, using balls torlon large diameter and each sphere in a breaking load of 812 kg. The speed that allows this pulley with high loads fully exploits the potential of higher performance systems, including counted down.

The cost is for one pulley.

TS pulleys are the heart of the Systems Roisub. Realized by special dedicated machines in a controlled environment and designed to work with heavy loads, using balls torlon large diameter and each sphere in a breaking load of 812 kg. The speed that allows this pulley with high loads fully exploits the potential of higher performance systems, including counted down.
Built with shell Derlin and Torlon ball bearings have tolerances than ever before. The spheres must always made by different and harder material than the material of the pulleys to minimize friction and improve performance.
Realized on a study ballistic meticulous represent the spearhead for all systems Roisub.
Even the egg shape designed by Roisub is unique and reduces 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.

Torlon vs Derlin
​The Delrin spheres are much cheaper than the Torlon spheres but are used for bearings with low load.
Torlon material is the best among all the existing ones with regard to the mechanical characteristics and rigidity / toughness.
The balls in torlon we use have been chosen with reference to specific features for use in our speargun.
A single ball in our Torlon (not the pulley which has various spheres but the single ball) has a breaking load of 812 kg and this is important because in time must avoid any ovalization to maintain maximum performance. Furthermore, the torlon has the highest wear resistance compared to derlin or other plastic material and has the lowest coefficient of friction.
These features ensure the maximum speed possible with high workloads to our TS pulleys pulley than any I've seen on the market.
​For use on systems Roisub (Fusion & Demo) there is no better solution.
