RBC Bearings announced May 20 that it is set to acquire VACCO Industries from ESCO Technologies for $310 million in cash.

South El Monte, CA-based VACCO is a manufacturer of vales, manifolds, regulators, filters and other precision components and subsystems for the space and naval defense channels.

For the 12 months ended March 31, the company had revenue of approximately $118 million.

VACCO will be integrated into RBC’s Aerospace and Defense segment upon deal closing, which is expected this summer.

“VACCO has a tremendous amount of design, engineering and manufacturing capabilities,” RBC Chairman and CEO Dr. Michael Hartnett said in news release. “Combining VACCO’s expertise in highly engineered valves, regulators and manifolds with RBC’s broader portfolio will enable us to better serve the evolving needs of customers in the secularly growing space and naval submarine channels.”

The deal will mark RBC’s first acquisition since it acquired Specline in the Summer of 2023 for $19 million.

Oxford, CT-based RBC is an international manufacturer of highly engineered precision bearings, components and essential systems, serving the industrial, aerospace and defnese channels.

RBC reported its 2025 fourth quarter and full year financials on May 16, showing total annual sales of $1.636 billion that were up 4.9% vs. 2024. The company had annual gross margin of 44.4% — up 140 basis points vs. 2024 — while net profit of $78 million jumped 17.8%.
