Webex Inc. is buying Maxcess International Corp. for an undisclosed amount.

Maxcess, which was owned by private equity firm Merifin Capital and Windjammer Capital Investors, manufactures automation instrumentation products. The Oklahoma City-based company’s products include magnetic particle clutches and brakes, steering guide systems and metals.

Webex, backed by private equity firm Bertram Capital, designs and manufactures precision rolls and handling machinery. The deal should allow the company to expand into new markets and provide customers with a broader product portfolio.
