The Spin Tec Roller furler for headsails takes a different approach than many of the other roller furlers on the market. First is the absence of a halyard to hold the Genoa or jib up instead a novel halyard lock is used. Second is the use of stainless and lack of ball bearings.
Update; Spin tec is no longer in business

The system is comprised aluminum foils, with delrin bearings spaced on the forestay. The foils slide together without the need for screws. Dissimilar metals are isolated and the all stainless drum is long so the furling line does not wrap too much onto itself unlike lower profile designs. This should ease the load on the furler line. The drum is easily detached from the furler extrusions.
The furling drum sits on delrin bearings which sit on the forestay turnbuckle assembly.
To hoist the headsail the plastic Halyard Accessory Clip, is used to hoist the sail with the halyard. A trip mechanism attached to sail to the top, and the halyard and clip are lowered back down. The image showing the top of the mast shows how the sail is attached.
A very simple effective design that should last for years for boats 27 to 60 ft
