Series HS20 Sealed Hollow Shaft

Technical Bulletin

DESCRIPTION

The Dynapar brand Series HS20 Sealed

Hollowshaft encoder is designed for easy

installation on motor or machine shafts. Its

hollowshaft design eliminates the need for a

flexible shaft coupling, mounting bracket,

flower pot, or flange adapter. This not only

reduces the installation depth, but also lowers

total cost.

The Series HS20 Sealed Hollowshaft's floating

shaft mount and spring tether minimize

bearing loads and eliminate flexible shaft

couplings to reduce wear and maintenance.
