AMLOK Rod Clamp
Amlok® Type RCH Rod Clamp
- Provides power-off clamping of rods and shafts
- Clamps are actuated by a spring/collet mechanism and unclamped by hydraulic pressure
- Designed to clamp components after the motion has stopped and to hold the position securely
as long as the forces do not exceed the table values
