■  Non-contact Gas Bearings

• Core technology of oil-free turbomachinery is non-contact gas bearings. We are very specialized in design, prototyping and testing of advanced foil bearings with various sizes, from 5mm up to 200mm in diameter. Bellkim Energy has exclusive license of foil bearings developed at University of Texas at Arlington. Core competency of our team is thorough knowledge and know-how on manufacturing process of foil bearings and their operating characteristics. Bellkim Energy helped many companies to develop oil-free bearing technology through technology transfer program.
• Based on extensive experience of many different bearing sizes and unique scaling law developed internally, scaling up/down of existing foil bearing design is accomplished without design/test iterations. Many our foil bearings applied to the commercial products are from initial prototype bearing without any further design change during entire development period, which often takes a few years.
