What is a Guide Vane Sleeve in a Hydro Bearing System?
In hydro turbines, particularly Kaplan and Francis types, the guide vane sleeve is a key component of the hydro bearing system. It provides rotational support, reduces friction during vane movement, and protects the shaft neck from wear. Traditional copper-based graphite mosaic bearings have long served this purpose — but INDRON® non-metallic guide vane sleeves offer a superior alternative.
Why Choose INDRON® Guide Vane Sleeves?
Our INDRON® guide-vane, connecting-rod, and regulating-ring bearings are specially engineered to meet the rigorous demands of hydroelectric power systems.
-
Oil-free operation: No lubricating oil is needed, reducing maintenance and environmental impact.
-
Full contact coverage: Larger bearing-to-shaft contact area than copper-based graphite sleeves.
-
Metal cladding option: Enhances protection for the shaft neck against wear.
-
Superior shock and vibration resistance: Effectively cushions impacts during the opening/closing of guide vanes, preventing cracks and mechanical fatigue.
