Bearings for Microturbines and Micro Generators

Microturbines and micro generators operate at extremely high speeds, elevated temperatures, and under continuous load. Reliable bearings are essential for ensuring long-term stability, precise operation, and maximum efficiency of these compact power units. We supply a wide range of specialized bearings designed specifically for high-speed and high-temperature microturbine environments.

High-Speed Precision Bearings for Microturbines

Microturbine systems often run at rotational speeds between 50,000 and 120,000 rpm, requiring advanced bearing designs that minimize friction and heat. We provide precision bearings with optimized cage materials, improved lubrication channels, and extremely low vibration characteristics.

• High-speed angular contact bearings
• Hybrid bearings with ceramic rolling elements
• Ultra-precision P4 and P2 grade bearings
• Low-friction designs for minimal energy loss

High-Temperature and Thermal-Stable Bearing Solutions

Microturbines are commonly used in energy recovery systems, small CHP units, and industrial gas applications where temperatures can rise significantly. Thermal stability is critical to prevent deformations and maintain tight tolerances during long-term operation.

• Bearings with high-temperature steel
• Special heat-resistant cages
• Thermal-stable races for continuous operation
• Lubrication options for extreme heat

Hybrid and Ceramic Bearing Options

Hybrid bearings with ceramic balls offer superior performance in micro generator assemblies due to lower weight, higher hardness, and minimal heat generation. These bearings are ideal for compact turbo machinery operating in demanding industrial or energy applications.

• Si3N4 ceramic rolling elements
• Low-noise, low-vibration design
• Extended service life under extreme loads
