Harken 177 1/4" Torlon Ball Bearings (21 pack) are high-performance replacement bearings designed to keep your sailboat’s hardware running smoothly under load. Commonly used in traveler cars, batten systems, and blocks, these precision bearings reduce friction and allow for effortless sail adjustments—even in demanding conditions.

Manufactured from advanced Torlon material, they deliver exceptional strength, durability, and resistance to wear. Compared to standard Delrin bearings, Torlon balls can handle significantly higher loads without deforming, making them the preferred choice for high-load or performance applications where reliability is critical.
