Sensing Gears are available in a variety of sizes to cover most applications
where a sensor is to be used, but a suitable existing machine gear is not
available. Split-type gears are convenient for use on machine drive shafts where
a shaft-end is not available to mount a standard gear. Hubless gears are ideal for
mounting in tight locations or when only a short shaft stub is available. Hub-
type, Split, and Hubless gears can be supplied with special bores (See notes
below Ordering Information & Dimensions table).
Caution: RLC’s machined steel sensing gears are NOT to be used as driving or
driven gears in a power transmission system.

ORDERING INFORMATION & DIMENSIONS
SPECIAL BORES: Hub-Type, Split, and Hubless gears can be supplied with
special bore sizes between the Stock Bore and Max. Special Bore sizes listed
above. To order Special Bores, substitute 9999 for the last 4 digits of the part
number and specify special bore size required.
ASSEMBLY NOTE FOR SPLIT GEARS: When tightening the split gear
halves on a shaft, it is recommended that the flat washer spacers be used to
help keep the gap between halves equal.
Run-out should be checked after installation is complete. Always use the
