39074-12-12 .375 .375 .315 min/in-oz 15 7.5 30

Notes on Couplings:
1. Bore is relieved to allow shafts to nearly butt.
2. Setscrews: Cup point, hex socket, #6-32. Two at each end, 90° apart.
3. Permitted axial motion from free length: ± .020.
4. Permissible shaft alignment: Angular up to 5° Parallel up to .010"

Installation Note:
To avoid coupling failure, be sure the shafts fit freely in the coupling bores and that the coupling is not compressed or subjected to greater deflections than specified above.



MEASURING WHEEL

This measuring wheel has a 12-inch circumference, aluminum hub and a high-durometer polyurethane rim. It attaches to a standard 3/8 inch shaft with dual set screws at 90 degrees.

Order BEI P/N 31196-001


PROTECTIVE HOUSING for Hollow Shaft Encoders

This cage is designed to protect hollow-shaft encoders from mechanical damage during handling and installation. For use with either the HS25 or the HS35 encoder, it has a side cutout to allow for tether arm placement. Installation hardware included.
