Enerpac NS-Series - Manual (Page 3)

Notes:
• The NS Series is available in both single and double acting
models. Single acting models use spring force to retract the
blade. Double acting models use hydraulic force to retract the
blade.
• A model number ending with “D” indicates that the nut splitter
(or cylinder sub-assembly) is double acting. Refer to Section 3.1
for model numbers and additional information.
• Both single and double acting models use the same NSH
series cutting heads shown in Section 3.1.
4.0 DESCRIPTION
The NS Series nut splitter is a hydraulically operated industrial
power tool, designed to quickly remove seized or heavily
corroded nuts from threaded studs.
See Figure 1 for an overview of NS nut splitter major features and
components.
A complete nut splitter consists of two separate subassemblies:
1) a single or double acting hydraulic cylinder and 2) a
matching cutting head designed for use with a specifi ed nut
size range. The replaceable cutting blade is installed in a blade
holder mounted on the shaft of the cylinder subassembly.
See Figure 2.
One cutting head is provided with each nut splitter. If desired,
additional cutting heads for diff erent nut size ranges can be
purchased separately from Enerpac.
Refer to sections 3.1 and 3.2 for nut splitter specifi cations and
additional information.
