Joint Bearing: Wear-Resistant, Flame-Resistant, Tear-Resistant, Heat-Resistant, Cold-Resistant INDRON® joint bearings of self-lubricating material are suitable for guide-vane bearings and connecting-rod bearings of tubular turbines.

Hydro Bearing → Joint Bearing INDRON® joint bearings of self-lubricating material are suitable for guide-vane bearings and connecting-rod bearings of tubular turbines.

Hydropower Bearing Bushing INDRON®hybron bearing can be flexibly assembled into split bearing with dovetail slat bearing bush, which is convenient for installation and maintenance without shaft extension, and more reliable when compared with the interference installation of cylinder bearing. If necessary during overhaul, the slat bearing bushes can be conveniently replaced, and a variety of homogeneous elastoplastic polymer alloy dovetail slat bearing bushes of different

Hydro Bearing → Water Guide Bearing As INDRON® TSTN elastic-plastic alloy is bonded with long-termed lubricative particles, its turbine guide bearings have excellent performances in self-lubrication and water lubrication, which overcome the problem of large starting torques resulting in the use of rubber turbine guide bearings and can effectively protect the shaft/bearing bushing. INDRON®hRBR elastic-plastic alloy have the advantages of good resilience, oil swelling

Hydro Bearing → Main Shaft Seal→ Face INDRON® TSTN elastic-plastic alloy has the advantages of low friction and wear both in clear water or water containing much mud and sand, which is more durable than ordinary metallic and non-metallic main-shaft sealing materials. Sizes are customizable for your unit so that material cost is lower and delivery lead time is shorter. Integrated with lubricating material to reduce wear and tear of anti-wear plate and water leakage. Natural

Hydro Bearing → Blade Seal The blade seals of turbines manufactured in early years in China have mostly used λ structure. However, the phenomenon of seal failures was widely found in the operations of most domestic units, which shows that this sealing form does not meet the requirements of long-term reliable operation of hydro-turbine units. After a long period of technical research, Techemer Composites has screened out the elastic-plastic polymer alloy with low friction

Hydro Bearing → Main Shaft Seal → Oil Deflector INDRON® oil and gas sealing material has excellent mechanical properties, good rigidity, toughness, hardness, wear resistance, small permanent compression set, excellent high and low temperature resistance, and excellent aging resistance. It is mainly used to prevent lubricating oil from leaking out or oil mist overflowing in the oil tank.

Hydro Bearing → Main Shaft Seal → Piston INDRON®hRBR main-shaft seals have the advantages of good resilience, oil swelling resistance and ageing resistance, which is an ideal alternative to rubber and polyurethane . We can provide materials of a variety of hardness to meet the requirements on installation and operation of different units, solving actual difficulties for you. Good resilience with only 13% permanent compression set, delivering durable and stable waterproof

Hydro Bearing → Joint Bearing INDRON® joint bearings of self-lubricating material are suitable for guide-vane bearings and connecting-rod bearings of tubular turbines.

Hydro Bearing → Guide Vane Sleeve → PLAT (Integral Type) Compared with regular copper-based mosaic graphite bearings, INDRON® guide-vane, connecting-rod and regulating-ring bearings have larger contact area and no lubricating oil is required. The metal-based cladding can effectively protect shaft necks from wear and tear. INDRON® guide-vane, connecting-rod and regulating-ring bearings can effectively cushion the vibration resulting from opening and closing of a guide vane and

Hydro Bearing → Guide Vane Sleeve → PLAT (Dx Type) INDRON® bearings with metal-based coating are an ideal alternative to oil – lubricated metal bearings for guide vanes, whose creative coating design has overcome the restriction of dry – ice installation for polymer bearings and eliminated the obvious clearance changes caused by the water swelling of polymer and thermal expansion. Best fit clearances are maintained thanks to tiny water swelling and dimensional changes.
