FLANGED SERIES
CYLINDRICAL O.D.
• Four sizes offered in flanged construction.
• Integral shoulders for mounting in through-bored housings.
• Straight outside diameters.
• Interchangeable with corresponding unflanged sizes.
• Available with double shields.
• Electric motor quality for applications where quietness
is required.
DIMENSIONS – TOLERANCES
TAPERED O.D.
• F Flanged series has shoulders integral with the bearings for
mounting in through-bored housings.
• Used where compactness is essential or where it is not
desirable to machine housing shoulders.
• All sizes in series have tapered outside diameters and are
available with double shields.
• Suitable applications include precision instruments,
packaging machinery and motion picture projectors.
• Several sizes in the series are manufactured in both standard
bearing-quality, chromium-alloy, high-carbon steel and
stainless steel (stainless steel specified by suffix “A”).
• Electric motor quality where quietness is required.
