ESG2 Overrunning GCr15 Indexing Freewheel Clutch
Feature
Type RIZ..ESG2 is a centrifugal lift off sprag type
freewheel when the inner race is overrunning. Only this race is
designed for freewheeling.
It is a self-contained unit designed for overrunning clutch
applications. Typically used in crawl drives where the overrunning
speed is high, but the drive speed is low and does not exceed the
maximum driving speed specified in the table.
It is a type RIZ (» see page 84 for further
information) equipped with an ES elastic coupling and a cover G2.
The ES type is a rugged coupling, economical and suitable for many
applications.
The inner race must overrun and will be connected to the
driven machine shaft. When ordered complete, the unit is delivered
grease lubricated, ready for either horizontal or vertical
installation.
