MA35N -- FLUID POWER PRODUCTS, INCLUDING AEROSPACE Annual 1994 Contact person: Renee Reda (301) 457-4742 Issued August 1995 SCOPE OF SURVEY-This survey covers producers of fluid power products, including aerospace except very small firms (generally less than 20 employees). SURVEY METHODOLOGY-The statistics in this publication are collected by mail on the Bureau of the Census annual survey Form MA35N, Fluid Power Products, Including Aerospace. The survey panel includes all known producers of fluid power products, approximately 503 companies. This survey does not include products produced and consumed within the same establishment. REVISIONS-Statistics for prior years may be revised as the result of corrected figures from respondents, late reports received for which imputations were originally made as described, or other corrections. Figures which have been revised by 5 percent or more from previously published figures are indicated by footnotes. HISTORICAL NOTE-Data on fluid power products have been collected by the Bureau of the Census in the Current Industrial Reports since 1981. Historical data may be obtained from Current Industrial Reports available at your local Federal Depository Library. A list of these libraries may be obtained from the Bureau of Census regional offfices. OBTAINING REPORTS-This report is available electronically through the Census-BEA Electronic Bulletin Board, accessed by dialing 301-457-2310. Your communications modem should be set as follows: Baud Rate: 1200, 2400, or 9600 Parity: None Stop Bits: 1 Data Bits: 8 Duplex: Full For help on using the bulletin board, read the tutorials from the Top Level Menu while on-line, or call the voice number at 301-457-1242. INQUIRIES-Address inquiries concerning further information on explanation of terms, additional related reports and methodological details to U.S. Department of Commerce, Bureau of the Census, Manufacturing and Construction Division, Washington, DC 20233-6900, or call Renee Reda, 301-457-4742. SUMMARY OF FINDINGS The statistics in this publication represents total U.S. shipments of fluid power products, including aerospace. Shipments of fluid power products, including aerospace in 1994 totaled $7,737.5 million. The 1994 total includes hydraulic and pneumatic valves, $1,978.6 million; fittings and assemblies for tubing and hose, excluding plumbers' brasss goods, $1,866.5 million; hydraulic and pneumatic clylinders, actuators, accumulators, cushions, and nonvehicular shock absorbers, $1,844.0 million; compressed air and gas dryers, and lubricators, $66.1 million; filters of hydraulic and pneumatic fluid power systems, $390.8 million; and hydraulic and pneumatic pumps, motors, and hydrostatic trans- mission components, $1,591.6 million.
