Bosch Rexroth Partners PETRONAS on Sustainable Hydraulic Fluids

Bosch Rexroth has formed a partnership with PETRONAS Lubricants International (PLI) to advance the development of bio-based and re-refined hydraulic and Universal Tractor Transmission Oil (UTTO) fluids. The partnership aims to create alternatives to conventional mineral oils, targeting greater energy efficiency and lower emissions for applications in the off-highway and agricultural vehicle sectors. Bosch Rexroth will set requirements and oversee qualification and testing, while PLI will take charge of fluid development, production, and distribution.

The initial focus is on a biodegradable, bio-based ester formulation for UTTO fluids used in hydraulic systems, gears, and wet brakes. According to the companies, this fluid is intended to combine energy efficiency gains with performance levels similar to existing mineral-oil products. Longer term, the collaboration may expand into wider industrial and stationary hydraulic applications, alongside work on a joint business model for sustainable fluids.

“This partnership with PETRONAS Lubricants International shows our broad understanding of responsibility as a leading hydraulics technology specialist and marks another step in driving the development towards sustainability also in the field of hydraulic fluids,” said Dr. Steffen Haack, CEO of Bosch Rexroth.
