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.
