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.
