· Revised Earnings Guidance for the Fourth Quarter

· Signed Agreement to Acquire Unico, Inc.

· Mark Gliebe to Become CEO at May 2011 Annual Shareholders Meeting


December 1, 2010 (Beloit, WI): In advance of the December 7, 2010 Investors
and Analyst Conference in New York, Regal Beloit Corporation (NYSE: RBC)
today revised its fourth quarter 2010 guidance to $0.63 $
0.67 per share. The
revision was due to a slower than expected sales pace in the HVAC segment
and acquisitionrelated
expenses that will be expensed in the quarter.

The company also announced today that it has signed an agreement to acquire
Unico, Inc., headquartered in Franksville, Wisconsin. Unico's sales for the fiscal
year ended June 30, 2010 were $61.7 million. Unico manufactures a full range of
AC and DC drives, motor controllers, and other accessories ideally suited for
most industrial and commercial applications. Unico has developed substantial
proprietary technology in the fields of oil and gas recovery technology,
commercial HVAC technology, test stand automation and other developing
applications. The transaction is subject to customary closing conditions and is
expected to close by year end. It is anticipated that the transaction will be
accretive to earnings per share by approximately 7cents in 2011.

Knueppel commented, "Unico is one of the most exciting acquisitions in RBC's
history. It is about bringing together a full electromechanical
solution for
customers. Investors should view this acquisition as the start of an adjacent
platform. Unico has experienced great organic growth and built a platform for
dynamic future growth. They have an incredibly talented leadership team that will
create the nucleus of this new platform for Regal Beloit. We believe the marriage
of our combined products will drive development and adoption of new energy
efficient and intelligent solutions. We simply could not be more excited about this
marriage."

Tom Beck, President and CEO of Unico, commented, "We view Regal Beloit as a
great home for the company we have built. Our companies have been on a
similar course with complementary products and technologies. This marriage
represents opportunities for faster growth and broader solutions. We too are
excited about what the future holds."

Finally, the company announced that Mark J. Gliebe, currently President and
COO, will assume the role of CEO at the next Annual Shareholders Meeting
expected to take place in May 2011. Mr. Knueppel will remain as Executive
Chairman through the end of 2011 to complete an orderly transition.

Commenting on the planned succession, Knueppel said, "Regal Beloit has
always been about the future, and this transition fits firmly in that tradition. As we
look to the future, it is a fantastic feeling to turn over the reins to a person of
Mark's caliber and capability. He is surrounded by a strong leadership team and
is respected by everyone who knows him. Mark has been a key player in the
transformation of the company into a global diversified industrial company with
top tier performance. Please join me in congratulating Mark on having earned his
new position."
