Jefa 69 mm Lower Rudder Bearing Self Aligning - 5BT069
The Jefa 5BT069 is a high-quality self-aligning lower bearing, specifically designed for sailing yachts where precision and durability of the steering system are essential. This bearing is part of the renowned 500 series from Jefa and offers a superior solution for rudder stocks with a diameter of 69 mm.
Thanks to the self aligning technology, the bearing automatically corrects small alignment errors between the hull and the rudder stock. This prevents friction and excessive wear, resulting in lighter and more direct steering behaviour, even under heavy loads at sea.
Key features and benefits
- Self-aligning capability: The inner workings can move freely relative to the outer housing, allowing for bending of the rudder shaft without the system locking up.
- Low friction: Made from high-quality materials that ensure minimal resistance, which is crucial for both manual steering and the efficiency of the autopilot.
- Low maintenance design: The plastics and alloys used are resistant to the corrosive effects of saltwater and require minimal maintenance throughout the season.
- Easy installation: This model is designed for mounting in a tube or directly in the hull, depending on the construction of your vessel.
