Harken Balls Seave Assembly 125 mm

HARKEN 125 mm Ball Bearing Sheave Assembly | High-Performance Fitting

Elevate the performance and reliability of your sailing vessel´s rigging with the HARKEN 125 mm Ball Bearing Sheave Assembly. As a crucial component in the Boats and equipment category, this high-quality fitting is engineered for sailors who refuse to compromise on efficiency and durability. Designed to dramatically reduce friction in high-load line systems, this sheave assembly ensures smoother sail handling, quicker hoists, and more precise trim adjustments, allowing you and your crew to perform at your best, whether you´re racing around the buoys or cruising in demanding conditions.

This assembly is a testament to HARKEN´s commitment to excellence. The core of its superior performance lies in its advanced bearing system. Sheaves are Hard Lube-anodized for maximum UV protection and a smooth surface. Captive Delrin® ball bearings carry side loads, ensuring the sheave runs smoothly and freely even under immense pressure. This meticulous design minimizes wear on your lines and reduces the effort required to manage powerful sails, translating directly to less crew fatigue and a more responsive sailing experience.

Key Benefits:

* Unmatched Low-Friction Performance: The integrated Delrin® ball bearings provide an exceptionally smooth surface for lines to run over, significantly reducing friction compared to standard plain-bearing sheaves. This makes hoisting, sheeting, and adjusting control lines faster and easier.
* Exceptional Durability and Longevity: The Hard Lube-anodization process creates an incredibly hard, low-friction surface that is highly resistant to corrosion, abrasion, and the damaging effects of UV radiation. This ensures the sheave maintains its performance and appearance season after season, even in the harshest saltwater environments.
* High Load Capacity: Engineered to handle the significant static and dynamic loads found in modern rigging systems. The captive bearings are specifically designed to manage side loads without binding, providing consistent reliability when you need it most.

The HARKEN 125 mm Ball Bearing Sheave Assembly is provided as a complete set, ready for installation into your existing blocks or custom fittings. Its precision engineering ensures a perfect fit and seamless integration, making it a straightforward yet impactful upgrade for any sailboat. Trust in HARKEN to provide the strength and efficiency your rigging demands.
