Exhibit 99.1
                                                                    ------------

Parker Reports Annual Sales Up 11 Percent, Earnings Affected by U.S. Industrial
Slump

CLEVELAND, July 30, 2001 -- As the manufacturing recession continues, Parker
Hannifin Corporation (NYSE: PH - news) today said the fourth quarter, which
usually is a strong one, weighed on the company's full-year results. Quarterly
net income excluding costs associated with operating realignments and other
corporate accruals was $66.8 million, or 57 cents per diluted share, compared
with last year's fourth-quarter income of $113 million, or 99 cents per diluted
share. For the full year, the company earned $340.8 million, or $2.96 per
diluted share, compared with $368.2 million, or $3.31 per diluted share, in the
prior year. The current-year results reflect a net benefit of five cents per
diluted share from non-recurring items, including a gain on the sale of real
estate, offset by the previously noted operating-realignment actions and
accruals; and the early retirement of debt. These results also reflect higher
interest expense and nearly 4 million additional shares outstanding issued for
acquisitions.

Acquisitions contributed much of the increase in annual revenues, which reached
$5.98 billion, up 11 percent from last year's sales record. "The acquisitions
we've made bring tremendous potential, not only contributing to the top line,
but strategically and operationally," said Parker CEO Don Washkewicz.

Noting that American industry is experiencing its first major setback since the
early 90s, Washkewicz said, "We've had to be fast and decisive in our response
to this downturn. Our manufacturing facilities were quick to adjust to depressed
market conditions, by consolidating operations, accelerating acquisition
integration and implementing spending cuts in all areas. These immediate moves
are painful and costly, but the flexibility to align ourselves with demand keeps
us strong and focused."

Operating Results & Supply Chain Initiatives

For the quarter and the year, Parker Aerospace led the company's operating
performance with higher income and margins attributed to operating realignments
and lean initiatives made throughout the business during fiscal year 2000, when
its major markets were down. Operating income in the Aerospace segment was up
more than 20 percent for the year, with an annual operating margin of 18.2
percent.

Conditions and comparisons were tougher for both the company's North American
and International industrial markets, particularly in the fourth quarter. In the
International Industrial business, operating income without operating
realignment costs was 17.3-percent lower in the quarterly comparison, but 5.5-
percent higher annually, at a 7.7-percent return on sales. Quarterly operating
income without realignment items in the North American Industrial business was
down 57.5 percent, while the annual income comparison was 11.4-percent lower.
For the year, the North American Industrial margin was 11.4 percent.

The company noted that with this report, further detail is provided with the
addition of an "Other" segment, which includes businesses outside of the
Industrial and Aerospace segments.


This new classification includes the company's climate controls and Astron
businesses, for which combined annual revenue is $556.8 million.

Operating income without realignment items for this segment was down 16.7
percent for the quarter and 9.3 percent for the year, with an annual return on
sales of 7.7 percent.

"Beyond actions we've taken for the current climate, we're also taking
aggressive steps across our supply chain to improve operating margins for the
long term," said Washkewicz. "Specifically, we're securing company-wide
procurement contracts. We are expanding lean initiatives worldwide; implementing
those that have proven so effective at Aerospace everywhere else in the company.
The fastest-paying rewards are in customer service, inventory management and
better asset utilization."

"And we continue to build on our greatest growth assets -- our people, our
products and our ability to provide engineered systems and solutions that yield
greater returns for us and our customers."

Outlook

The company noted it remains cautious in its outlook for the next quarter and
the fiscal year. Going forward, with its early adoption of FAS 142 provisions,
the company will not amortize goodwill, accounting for 44 cents in the new
fiscal year. After this effect, Parker said it expects first-quarter earnings to
be between 50 and 65 cents per share, and, with the beginnings of an economic
recovery anticipated in the second half, fiscal year 2002 earnings are expected
to range from $2.90 to $3.35 per share.

In addition to providing earnings estimates, Parker advises shareholders to note
order trends, for which the company makes a disclosure several business days
after the conclusion of each month. This information is available on the
company's investor information web site, at www.phstock.com.

With annual sales of $6 billion, Parker Hannifin is the world's leading
diversified manufacturer of motion and control technologies and systems,
providing precision-engineered solutions for a wide variety of commercial,
mobile, industrial and aerospace markets. The company employs more than 45,000

Forward-looking statements contained in this and other written and oral reports
are made based on known events and circumstances at the time of release, and as
such, are subject in the future to unforeseen uncertainties and risks. All
statements regarding future performance, earnings projections, events or
developments are forward-looking statements. It is possible that the company's
future performance and earnings projections may differ materially from current
expectations, depending on economic conditions in North American industrial
markets and the company's ability to achieve anticipated benefits associated
with announced inventory


reductions and restructuring and acquisition-integration activities. Among the
other factors which may affect future performance are: changes in business
relationships with and purchases by or from major customers or suppliers,
including delays or cancellations in shipments; competitive market conditions
and resulting effects on sales and pricing; increases in raw-material costs that
cannot be recovered in product pricing; and global economic factors, including
currency exchange rates, difficulties entering new markets and general economic
conditions such as interest rates. In each quarterly earnings report, the
company intends to provide a range stating expected earnings per share for the
succeeding quarter and full fiscal year, reflecting these ranges as estimates of
diluted earnings per share before unusual items. The company makes these
