Aluminum Radial® Self-Tailing Winche
Harken Aluminum Radial® winches are designed for sailors who want lightweight, extremely strong winches with plenty of power. The drum's gripping surface is shaped for each winch size and drum material, and it features diagonal ribs (rather than textured abrasive materials) to maximize gripping power and greatly reduce line wear. When easing, the angle of the ribs stops line from rising, preventing overrides and providing a smooth, controlled release as the line exits the winch. Aluminum drums and high-strength composite self-tailing jaws and skirt save weight. Composite roller bearings reduce friction under load and don't require lubrication. Load-carrying gears and pins are 17-4PH stainless steel for strength and durability.
Roller Bearings
Snap-fit design keeps bearings captive in a high-strength Delrin® cage when drum is removed for maintenance. Composite roller bearings don't require lubrication. (Delrin® is a registered trademark of E. I. du Pont de Nemours and Company or its affiliates.)
Gripping Surface
Each winch size has its own radial grip shape to optimize holding power and for smooth, controlled easing.
