Turbine Radial Thrust Bearing
Precision Under Pressure. Engineered for Rotational Balance and Axial Load Support.
Turbine radial thrust bearings are specialized bearing assemblies designed to support both the radial (rotational) and axial (thrust) loads in high-speed turbine systems. These bearings are critical in maintaining rotor stability, minimizing shaft vibration, and ensuring long-term reliability of steam, gas, and hydro turbines.
Developed for extreme speed, temperature, and pressure conditions, turbine radial thrust bearings are built with precision-grade materials, advanced oil-film lubrication systems, and engineered clearances to sustain continuous operation under dynamic loads. Whether in thermal power plants or renewable hydroelectric setups, they serve as the heartbeat of the turbine assembly.
Application:
Where Are Turbine Radial Thrust Bearings Used?
These bearings are essential in power generation systems where the turbine shaft needs to be held in perfect alignment while managing massive axial and radial forces.
| Industry | Applications |
| Thermal Power Plants | Steam turbines, turbo-generators |
| Hydropower Stations | Kaplan and Francis turbines |
| Gas Turbine Systems | Combined-cycle plants, gas boosters |
| Petrochemical Plants | Turbomachinery, axial compressors |
| Renewable Energy | Wind turbines with hybrid bearing systems |
What Is a Turbine Radial Thrust Bearing?
A turbine radial thrust bearing is a dual-function bearing assembly that supports both radial loads (perpendicular to the shaft) and axial loads (along the shaft’s length). It ensures the turbine rotor remains centered and absorbs axial displacement caused by steam or gas pressure variations.
The assembly typically includes:
- Radial Journal Pads or Sleeves – For supporting the rotating shaft
- Thrust Pads – To handle axial movement in one or both directions
- Tilting Pad Design – To optimize hydrodynamic film thickness and load distribution
- Lubrication Grooves / Oil Supply System – Critical for film formation and cooling
- Bearing Housing – Precision-machined body for mounting and alignment
These bearings prevent shaft misalignment, thermal distortion, and excessive wear under high-speed, high-temperature operating conditions.
High-Grade Materials for Maximum Performance
Turbine bearings must operate under continuous thermal and mechanical stress. Hence, materials are carefully chosen to resist deformation, fatigue, and thermal breakdown.
| Component | Material Used | Key Characteristics |
| Radial Pads / Journal | White Metal (Babbitt) or Tin Bronze | Conformability, wear resistance, good embedment |
| Thrust Pads | Steel Backing with White Metal Overlay | High shock absorption and load-carrying capacity |
| Bearing Housing | Cast Steel, SG Iron | Precision alignment, vibration damping |
| Coatings / Inlays | PTFE or Graphite (optional) | Dry lubrication, low-friction backup |
Lead-free and RoHS-compliant white metals are available for regulated environments.
