CH(D)2, JIS Hydraulic Cylinder, Double Acting, Single Rod
CH2 double acting hydraulic cylinders conform to JIS B 8367 specifications. Surge pressure generated when running into the cushion has been reduced by 30% or more compared to the CH series, due to the CH2's cushion seal system. Separate construction of the rod cover simplifies maintenance. Available in bore sizes 32mm to 100mm. All series types are available with auto switch capability with the exception of the steel tube type.

∗1 Water resistant type auto switches can be mounted on the above models, but in such case SMC cannot guarantee water resistance.
The water resistant type CH2F series is recommended for use in an environment which requires water resistance. Consult with SMC regarding the water resistant type CH2E, CH2G and CH2H series.

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
