Lubrication Engineers, a portfolio company of Aurora Capital Partners, has acquired RSC Bio Solutions.
RSC Bio Solutions develops and supplies high-performance, environmentally acceptable lubricants (EALs) used in marine and industrial applications. The company’s product portfolio includes FUTERRA biodegradable hydraulic fluid, EnviroLogic lubricants for marine vessels and sensitive environments, and BioFlo EAL gear oils, which are used to meet regulatory compliance and sustainability goals in equipment operating near water.
Customers of RSC Bio include marine operators, offshore energy companies, and industrial machinery users seeking renewable base oil alternatives. RSC Bio was founded in 2010 by CEO Mike Guggenheimer and is headquartered in Charlotte, North Carolina, with an additional facility near Cleveland in Bedford Heights, Ohio.
“We are excited to join forces with Lubrication Engineers to expand our capabilities and accelerate our innovation that benefits both our customers and the environment,” said Mr. Guggenheimer. “We have long admired Lubrication Engineers as a leader in our industry, and we look forward to leveraging its robust infrastructure in support of our current and prospective new customers.”
Lubrication Engineers was acquired by Aurora Capital Partners in September 2023, and the buy of RSC Bio is its second add-on acquisition following the March 2025 acquisition of the industrial brands and products — synthetic lubricants, greases, and fluids — of Royal Purple from publicly traded Calumet for $110 million (Aurora Carves Royal Purple Industrial from Calumet).
Lubrication Engineers is a manufacturer and distributor of industrial lubricants and greases that enhance and maintain equipment performance and longevity. The company’s product portfolio includes Almasol industrial lubricants, Monolec synthetic gear oils, and Pyroshield open gear lubricants, which are used in applications across manufacturing, power generation, petrochemicals, and heavy equipment industries.
Through its network of distributors and technical service representatives, the company’s products are sold to customers in more than 60 countries. Lubrication Engineers, led by CEO Eric Borland, was founded in 1951 and operates a 150,000 sq. ft. manufacturing facility in Wichita, Kansas.
“RSC Bio Solutions has an impressive portfolio of sustainable products powered by proprietary technologies developed over multiple decades,” said Mr. Borland. “Together with the employees of RSC Bio Solutions, we are committed to ensuring the continued delivery of high-quality, sustainable products to customers across the globe.”
Aurora Capital Partners makes control investments of $50 million to $300 million in industrial, manufacturing, and service-oriented businesses valued between $100 million and $500 million. The firm focuses on sectors including industrial services and distribution, engineered products, and technology-enabled services.
