Compact Equalising Thrust Bearings

Space-Efficient Axial Load Solutions for High-Performance Rotating Machinery

Dawopu Compact Equalising Thrust Bearings are advanced hydrodynamic thrust bearings specifically engineered to support heavy axial loads while maintaining a compact structural design. These bearings incorporate an equalizing mechanism that automatically distributes load evenly across the bearing pads, ensuring reliable operation even under fluctuating thrust conditions.

In modern rotating machinery, space limitations and increasing performance demands require bearing systems that provide high load capacity within a reduced installation envelope. Compact equalising thrust bearings meet these requirements by combining a space-saving structure with advanced load balancing technology.

At Dawopu, compact equalising thrust bearings are designed using optimized pad geometry, precision pivot mechanisms, and efficient lubrication systems. These features ensure stable rotor positioning, reduced friction, and long-term operational reliability.

They are widely used in steam turbines, compressors, pumps, gearboxes, and other heavy-duty rotating equipment where space is limited but performance requirements remain extremely high.

Working Principle

Compact equalising thrust bearings operate based on the principle of hydrodynamic lubrication and mechanical load equalization.

The bearing assembly consists of several thrust pads mounted on a self-equalizing support system. When the shaft rotates, the thrust collar drags lubricating oil into the clearance between the collar and the pads, forming a pressurized oil film. This oil film separates the metal surfaces and supports the axial load.

The equalizing mechanism ensures that the load applied to the bearing is distributed evenly across all pads. If one pad experiences higher load than the others, the equalizing system adjusts automatically, transferring load to adjacent pads and maintaining balanced pressure.

This self-adjusting feature improves reliability, minimizes local overheating, and enhances the overall service life of the bearing.

Key Features of Dawopu Compact Equalising Thrust Bearings
