Note 1)
Refer to pages 230 and 231, to determine stroke limitation depending on the type of mounting brackets that will be
used. Then make yur selection. Long stroke ranges also differ depending on the type of mounting brackets.
Note 2) The long stroke range for the CH2E, CH2F, and CH2H series with flange and clevis type mounting brackets as
well as the CH2G series is up to 1400 mm.
Note 3) The long stroke range for the CH2E, CH2F, and CH2H series with flange and clevis type mounting brackets as
well as the CH2G series is up to 1500 mm.
