Thrust Block⇦■Features・Robust structure integrated into the casting is applied.
・The highly rigid type is reinforcing the backup wall of Cam Slider B. It is not necessary tomachine the die for backup.
ⓑ・V-shaped Cam Slider B is highly resistant to the reaction force on the side. (145 / 245 / 320mm wide only)
スラストブロック・Urethane Stopper for shock absorption are provided on the Stopper Plate to prevent direct
force on the screws.
・The Thrust Block is installed as the Stopper of Cam Slider B. This Stopper Block could
prevent the Cam Slider B from lifting up over the specified stroke.
・A thread hole is drilled so that a Pushing Bolt for the end-position kit could be installed.
