Engineered Tilt Pad Thrust Bearings for Demanding Service

Tilt pad thrust bearings support axial loads in high-speed rotating machinery by forming a stable hydrodynamic oil film between the thrust collar and pivoting pads. Each pad self-aligns on a pivot, creating an oil wedge that carries load and prevents metal-to-metal contact. This design limits hot spots, reduces wear, and delivers reliable operation where fixed-surface thrust plates fall short. When the work is critical and uptime matters, correctly engineered tilt pad thrust bearings provide the temperature control, film stability, and efficiency that modern equipment requires.

Fusion Babbitting designs, manufactures, and repairs tilt pad thrust bearings to your specifications. Our team considers your loads, speeds, collar geometry, lubrication method, and ambient environment, then tailors materials and pad geometry to your service. From new OEM builds to emergency rebuilds, we deliver thrust bearings that match or exceed original performance and help protect your shafting, seals, and rotors.

How Tilt Pad Thrust Bearings Improve Performance

The pad design is the heart of thrust bearing performance. Each pad pivots to create the correct oil film thickness across the pad face. As speed and load change, the self-aligning pad helps maintain the hydrodynamic wedge, spreading the load and limiting friction. Advantages include lower operating temperatures, higher load capacity per pad area, stable performance through load cycles, and reduced wear during start-stop conditions when supported by the right oil and lift features.

  • Enhanced oil film stability due to pivoting pads
  • Lower friction and energy loss compared to flat thrust washers
  • Improved tolerance to misalignment and thermal growth
  • Flexible configuration with pad count, size, and arc length tuned to your application
  • Better thermal management with directed lubrication and controlled oil drain paths

Design Options for Custom Tilt Pad Thrust Bearings

Material Selection

Fusion Babbitting recommends Babbitt materials based on speed, load, and oil chemistry. Tin-based Babbitt offers strong fatigue resistance and is common for high-speed, high-load service. Lead-based options can be appropriate for moderate speeds and shielded environments. Backing materials include steel or bronze depending on weight, thermal expansion, and compatibility with your housing. Where start-stop cycles are frequent, we can integrate surface features and oil lift provisions to protect the Babbitt layer during boundary lubrication events.

Every batch of Babbitt is certified. Centrifugal casting provides uniform bonding and controlled microstructure, which is essential for long life under fluctuating loads. Pads are machined to precise thickness and flatness tolerances, then finished to achieve the correct surface roughness for oil film formation.

Pad Geometry and Pivot Styles

Pad geometry has a direct effect on film stability and operating temperature. Our engineers optimize pad arc length, thickness, preload, and offset pivot placement to promote wedge formation at your design speed. We tailor the number of pads and the total load per pad to fit housing constraints and your thrust collar width. Pivot types include spherical, rocker, and fixed geometry designs. Equalizing hardware can be used to distribute load in machines with varying axial forces.

  • Pad count and arc length sized for collar diameter and available envelope
  • Offset pivot to promote stronger leading-edge film and reduce pad temperature
  • Preload and taper options to manage film thickness and lift
  • Equalizing link or leveling mechanisms when load sharing is critical
  • Replaceable pad and pivot designs to simplify future maintenance

Lubrication and Cooling

Lubrication strategy drives bearing life. Fusion Babbitting supports both flooded and directed lubrication. We can incorporate leading-edge grooves, dams, and controlled drain paths to improve oil flow across the pad face. For high-speed service, directed oil to the leading edge improves cooling and reduces power loss. Lift oil jacking ports are available to reduce wear during startup and shutdown. We also coordinate with your oil system requirements, including target flow rates, viscosity, and temperature control.

  • Flooded lubrication for steady cooling in moderate speed equipment
  • Directed lubrication for high-speed, high-load thrust faces
  • Leading-edge grooves and entry features to stabilize the film
  • Lift oil designs for safe start and stop cycles
  • Oil outlet management to prevent churning and aeration

Thrust Collar Interface

Thrust collar finish and flatness are vital. Fusion Babbitting can inspect and refurbish collars or reverse engineer replacements. We recommend collar surface finish and hardness that match your pad material and oil film requirements. Proper collar geometry and surface integrity promote even loading and extend pad life by protecting the Babbitt from localized stress.

Quality Assurance and Testing

We maintain checks from raw material through final inspection. Bond strength is verified on every centrifugal cast component. Dye penetrant and ultrasonic inspection can be applied to high-value parts. Dimensional checks confirm pad thickness, flatness, and pivot location. Surface finish is controlled on all pad faces and critical interfaces. Fusion Babbitting provides complete documentation upon request so you can maintain reliable records across your fleet.

  • Babbitt bond assessment after centrifugal casting
  • Dimensional inspection of pads, pivots, and housings
  • Surface roughness checks on working faces
