Description de produit
Custom Tilting Pad Bearings for Steam Turbines
Product Overview

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.

Core Customization Advantages
Full Customization to Match All Turbine Models
  • Customizable shaft bore diameter, bearing shell outer size, split structure
  • Pad quantity (3/4/5/6 pads), pad thickness, lubricating oil groove layout
  • Oil inlet & drain holes configuration
  • Compatible spare parts for all brand steam turbines
  • Flexible order support: Single emergency maintenance spare parts & mass batches for new power plant construction
Premium Wear-Resistant Composite Materials
  • Bearing base: High-strength cast steel / alloy steel bearing shell with high rigidity and deformation resistance under heavy rotor load
  • Bearing pad surface: High-performance babbitt alloy (tin-based / lead-based) centrifugally cast, excellent anti-friction, impact resistance and temperature tolerance
  • Optional copper alloy backing pads for ultra-high load working conditions
  • Complete Material Test Certificates (MTC), chemical composition and mechanical test reports provided for power plant acceptance
Precision Manufacturing & Advanced Process
  • 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
Superior Vibration Suppression Performance
  • 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
Strict Multi-Stage Quality Inspection
  • 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
