Ronstan Series 30 Ball Bearing Block

Introducing the Ronstan Series 30 Ball Bearing Block, a premium product designed for maximum performance and durability. This innovative block features a single becket option lashing, making it versatile and easy to use. Engineered with the highest strength-to-weight ratio available, this block is constructed from all-composite reinforced polymer materials, ensuring exceptional longevity and reliability. Its precision design incorporates the optimal number of ball bearings for minimal friction, while the use of fibre-reinforced composites in the block head, cleat arms, and beckets reduces weight without compromising strength.

Advanced Features and Specifications

The Ronstan Series 30 Ball Bearing Block is equipped with a proven 2-stage bearing system, which includes high compression grade Acetal ball bearings and a secondary full-contact bearing. This innovative design ensures minimum friction across the full working load range, providing smooth operation and increased efficiency. The sheave and bearing system are supported by a fibre-reinforced load frame, which is computer modelled and optimized using advanced stress analysis methods. The Dyneema® Link, a high-spec SK75 fibre, is used in multi-sheave blocks, offering a connection that is 10 times stronger and lighter than steel. This link provides a secure final connection from the block to the load point, enhancing the block's overall performance.

Practical Applications and Benefits

Perfect for a variety of applications, the Ronstan Series 30 Ball Bearing Block is ideal for mainsheet systems and spinnaker sheets on dinghies up to 5M (16'), as well as halyard, vang, and backstay applications on boats up to 5M (16'). Its control line applications on larger yachts are also highly beneficial. The block's simple, versatile, and secure attachment options, including Dyneema® Links and shackles, make it a versatile choice for various attachment alternatives. Additionally, the low profile and compact design, with the two-way head allowing for alignment at 0° or 90° orientation, make it a space-saving solution. The ultra-low profile thru-sheave becket and self-lubricating Nylatron® sheave with full contact bearing for high dynamic loads further enhance its practicality and performance. With the Ronstan Series 30 Ball Bearing Block, you can expect a lightweight, durable, and efficient solution for all your boating needs.
