RBC Bearings Incorporated Announces New $150 Million 5-year Revolving Credit Facility

Oxford, CT — June 27, 2006 — RBC Bearings Incorporated (Nasdaq: ROLL), a leading international manufacturer of highly-engineered precision plain, roller and ball bearings for the industrial, defense and aerospace industries, today announced the establishment of a new $150 million 5-year senior secured revolving credit facility. The new facility provides more favorable terms and conditions, better pricing and improves the Company’s liquidity.

Terms of the facility include a $150 million revolver with an option to borrow an additional $75 million under certain circumstances. The facility pricing is grid based, with initial pricing that is approximately 175 basis points lower than the Company’s prior credit facility. The new credit facility will be used to fund working capital and potential acquisitions.

“The successful syndication of this bank facility is a vote of confidence from our bank group in our operations and our growth prospects,” said Dr. Michael J. Hartnett, Chairman, President and Chief Executive Officer. “The new facility provides us with increased flexibility and will allow us to continue to drive improvements across the company, execute on our growth strategy and increase shareholder value.”

The Company used approximately $78 million of borrowings under the new credit facility to retire $78 million of term loan debt outstanding in its prior credit facility and replaced $21 million of outstanding letters of credit. As a result, in the first quarter fiscal 2007, the Company will record a non-cash, after-tax charge of approximately $2.2 million or $0.11 per share in deferred debt issuance costs associated with the early termination of the facility that was replaced. After-tax cash interest savings from the deal, assuming an average borrowing under the new facility of $78 million and outstanding letters of credit of $21 million, will be approximately $1.1 million or $0.05 per share in fiscal 2007. As of June 27, 2006, the Company had approximately 21.0 million fully diluted shares outstanding.

Co-Lead Arrangers and Joint Book Runners for the transaction were KeyBanc Capital Markets and JP Morgan Securities Inc. For further information, please see the Company’s most recent filings with the Securities and Exchange Commission.
