Custom Design Tilting Pad Bearings with Wear-Resistant Composite Materials for Superior Vibration Suppression in Steam Turbines

Our custom tilting pad bearings (also known as tilting pad journal bearings) are core support components for steam turbine rotors, widely applied on high-pressure, intermediate-pressure and low-pressure rotors of thermal power generating units.

Every bearing set is tailor-made based on turbine rotor weight, rotating speed, operating temperature, shaft diameter and client engineering drawings. The split tilting pad structure allows each bearing pad to self-adjust its oil wedge angle automatically under dynamic load, forming uniform hydrodynamic oil film between shaft and pads. This design effectively suppresses oil whirl vibration, reduces rotor friction loss, and guarantees stable long-term high-speed operation of turbine equipment.

• Integral casting + CNC fine boring & milling for bearing shells, tight dimensional tolerance to ensure perfect fit with bearing housings
• Centrifugal casting babbitt layer, uniform bonding without peeling or air bubbles; ultrasonic inspection for bonding quality
• Precision scraping on pad working surfaces to form stable hydrodynamic oil wedge
• Optional surface treatments: Anti-rust passivation, nitriding strengthening for extended service life

• Self-adjustable tilting pads eliminate oil whirl and oil whip faults, greatly reducing unit vibration value
• Even load distribution across all pads, avoiding local overheating and pad burnout
• Strong adaptability to variable load and frequent unit start-stop cycles
• Low friction loss, lower lubricating oil temperature rise, reducing auxiliary system energy consumption

• Raw material inspection: Spectrum analysis, hardness testing, flaw detection for steel shell and babbitt alloy
• Babbitt bonding test: Ultrasonic flaw detection to check for delamination defects
• Finished precision testing: CMM full dimension measurement, contact scraping inspection, oil flow channel simulation test
• 100% visual appearance inspection before export packaging
• Full set of inspection documents delivered together with goods
