Description

Ronstan Series 100 Strop Orbit Block, Single

Orbit blocks are a no-compromise product range developed to meet the demands and expectations of the very dedicated and increasingly professional racing sailor. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners. The Orbit sheave has captive acetal or Torlon ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon needles – achieving a substantially higher strength-to-weight ratio.

Features:

• The highest strength-to-weight ratio.
• Minimal friction loss, especially when working at high loads.
• Captive ball bearings for side thrust loads.
• Totally reliable and trouble free performance.
• Simplicity of design and construction to facilitate maintenance and servicing.
• Elegant, functional styling and finish.
