  • 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.

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

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

Custom solutions can be developed to suit individual requirements.
