Ronstan manufactures an extensive range of sheave boxes for use with rope and wire. Plain bearing sheaves are ideal for halyards and other applications where high static loads are likely to be encountered.

Range Selection Advice
  • Ideal for applications where lines (rope or wire) need to be led through decks, bulkheads or spars minimising friction and chafing
  • Nylatron® sheave
  • Grade 316 stainless steel cheeks
