Due to the high-speed axial and centrifugal conditions, compressors often require the technologies of tilting pad journal and thrust bearing. It is crucial to enhance the efficiency by using directed lubrication and Cr/Cu backed pad materials. What’s more, compressors can get benefit from utilizing active magnetic bearing technology, enabling oil-free and dependable operation.

Application of Tilting Pad Journal and Thrust Bearings in Compressors

Compressors—particularly high-performance centrifugal and axial types—operate under extreme conditions of rotational speed, pressure, and thermal fluctuation. Whether used in oil & gas processing, chemical plants, or air separation units, these machines rely heavily on bearing systems that provide precise rotor control, vibration suppression, and long-term durability.

At Journal Bearings, we provide engineered tilting pad journal and thrust bearing solutions specifically optimized for compressor applications. Our bearings are designed to perform reliably in high-speed, high-load environments, minimizing downtime and enhancing machine efficiency.

Why Compressors Need Tilting Pad Bearing Technology

1. High-Speed Stability

Centrifugal and axial compressors often operate at 20,000+ rpm, which challenges the stability of conventional fixed-geometry bearings.
Tilting pad journal bearings provide individual pivoting support for each pad, enabling the formation of a dynamically stable hydrodynamic film, even at high shaft speeds and under misalignment.

2. Axial Load Control

Compressor rotors experience significant axial forces due to pressure differentials and gas flow direction.
Our tilting pad thrust bearings are engineered to maintain axial alignment and prevent rotor shifting—thereby ensuring consistent performance and reducing the risk of failure.

3. Directed Lubrication System

To reduce power losses and temperature rise during continuous operation, we integrate directed lubrication channels into our bearing housings. This technology:

• Improves oil flow targeting

• Minimizes pad surface temperature

• Reduces energy consumption

• Extends bearing and rotor service life

4. Advanced Materials: Cr/Cu-Backed Pads

For compressors with extreme thermal or load demands, we offer copper-chromium (Cr/Cu) backed pads, which deliver:

• High thermal conductivity

• Superior resistance to deformation under load

• Enhanced babbitt bonding integrity

• Lower risk of pad delamination under thermal stress

Optional Integration with Active Magnetic Bearings

In highly advanced oil-free compressor systems, active magnetic bearings (AMBs) are increasingly being adopted to eliminate lubrication systems altogether.
At Journal Bearings, we provide hybrid bearing solutions that combine traditional tilting pad technology with backup bearing designs to protect AMB systems during transient or emergency shutdown conditions. These systems enable:

• Oil-free operation

• Lower maintenance requirements

• Greater energy efficiency
