  • Precision machined bodies and Torlon® ball bearings ensure free running performance even under extreme loads
  • Custom solutions can be developed to suit individual requirements

  • Share:

Car bodies are machined to precise specifications, then honed to an exceptional finish before being treated and anodised for maximum corrosion protection. Stainless steel elements are put through a special high energy finish process to achieve a uniquely smooth edge and surface finish.

High performance roller ball bearing sheaves for low friction performance can accept two sheets for easy headsail changes.

Highly polished stainless steel stirrups pivot 45 degrees from vertical for optimum alignment with sheet loads.

Custom solutions can be developed to suit individual requirements.

Adjustable stops can be used as a backup to lock a car into position. The plunger stop can be locked in the "up" position.

Genoa cars have a towing lug and twin rows of recirculating Torlon ball bearings for each adjustment under load. Custom variants are available with an additional lug aft for towing cars in series.
