Check alignment before operating machine. Misalignment between Safety Chucks interferes with the proper
functioning of the system and decreases product life. The following specifications must be met for proper alignment:
• Mount Safety Chucks at same height with respect to the center-line of the machine roller
• Mount Safety Chucks at same distance from the center-line of the machine roller
• Mount the Safety Chucks parallel with transport rollers in the machine
• Mount only to a flat surface ±0.0 mm [±0.004 in]
• ensure alignment on all axis
NOTE: Deflection of either the mounting frame or shaft under the load can substantially reduce product life.
NOTE: Nexen recommends maintaining a 0.5 mm [0.02 inch] clearance between the back of the Safety Chuck
Socket and the end of the shaft journal.
Verify alignment on both the vertical and horizontal
planes.
. Insert an empty square shaft into the two Safety
Chucks following the INSTALLATION procedures.
2. Place a level on top of the square shaft to ensure
Chucks are aligned on the same vertical plane.
3. Adjust height using appropriate materials and repeat
step two until the shaft is level.
4. Locate the nearest roller on the machine.
5. Determine the center of the transport roller.
6. Measure the distance from the center of the
transport roller to the back of each Safety Chuck
socket.
7. Adjust chuck position until the distances from the
center of the transport roller are equal.
