NOTE:
For exchange of components please return the
complete gripper with a repair order to SCHUNK.
In order to achieve proper function of the grippers,
please note the following:
1) Make sure that the blank steel components
are lubrified or greased.
2) Lubrify the base jaws of the gripper every
500.000 cycles with Molykote BR2 plut,
Metaflux-Gleitmetall or any equivalent lubri-
cant. The funnel-type lubrication nipple DIN
3405 AM 8 x 1 are at the base jaws.
The jaws do not move:
– The hydraulic supply is interrupted.
– Break of screws at the connection between
the piston bar and the base jaw.
– The connections are misaligned.
The clamping force reduces:
– Break of screws at the connection between
the piston bar and base jaw.
– There is dirt and dust between the
guidances of the base jaws.
– Internal oil leakage
OiI leakage at the bottom:
– Set-screw M 6 for direction connection
without hoses is not sealed correctly
(see page 5).
