Bearings play a critical role in the operation of gas turbines, which are widely used for power generation, aviation propulsion, and mechanical drive applications. These precision components support rotating parts while minimizing friction, enabling the high-speed operation that characterizes modern gas turbine technology.

Types of KOYO Bearings Used in Gas Turbines

1. Journal Bearings

Hydrodynamic fluid film bearings are most common

Support radial loads in the turbine and compressor sections

Operate on the principle of creating an oil wedge between the shaft and bearing surface

2.KOYO Thrust Bearings

Designed to handle axial loads generated by gas turbines

Typically tapered land or tilting pad designs

Position the rotor axially within the casing

3.KOYO Rolling Element Bearings

Used in some aeroderivative and smaller gas turbines

Ball bearings often support auxiliary systems

Offer lower friction but have load limitations compared to hydrodynamic bearings

Key Requirements for Gas Turbine Bearings

1. High Temperature Capability

Must withstand temperatures up to 300°C (572°F) for oil systems

Special materials and cooling required for extreme environments

2. Extreme Reliability

Designed for continuous operation with minimal maintenance

Typical service life exceeding 100,000 hours

3. Vibration Control

Precision manufacturing to minimize vibration

Damping features to absorb rotor dynamic forces

4. High-Speed Performance

Surface speeds can exceed 150 m/s (30,000 ft/min)

Special designs to prevent oil whirl instability

KOYO Bearings are fundamental components that enable the reliable, high-performance operation of gas turbines across industries. Continuous advancements in bearing technology contribute to improved turbine efficiency, reduced maintenance requirements, and extended service life.
