The whole “composite fiber” range uses sheaves on composite fiber bearings and double self-captive Delrin ball thrust bearings.

The sheaves are easy to dismantle for cleaning and need no lubrication. The sides are made of 3571 TA16 light alloy and are thickly anodized to ensure absolute wear-and corrosion proofing, with all the edges smoothed off for better handling. The nuts and bolts have been replaced with recessed screws and pins, considerably reducing weight and eliminating any projecting parts.

The steel coupling revolves on a fiber washer and can easily be locked in one of two main positions. Sheaves. Sizes 90, 150, 180, 220 and 250 mm use thickly anodized aluminum sheaves. The main bearing is made of high-strength composite fiber impregnated with self-lubricating substances. A double lateral Delrin ball bearing makes the sheaves slide perfectly smoothly. Sheaves are supplied with the s.steel central hub, they are available separately.
