Ronstan Series 40 Orbit Block Ball Bearing with Link Head

The Ronstan Series 40 Orbit block with ball bearing system and link head is designed for high-performance applications where speed, efficiency, and weight reduction are essential. The ball bearing system ensures extremely low friction and smooth rotation, even under dynamic loads.

The integrated link head provides a lightweight and flexible connection, allowing the block to align naturally with the load direction. This improves efficiency and reduces wear on both the rope and hardware.

With its compact Orbit design, this block offers an excellent strength-to-weight ratio, making it ideal for modern sailing systems. Available in single and double sheave configurations, it supports both simple and more advanced line setups.
