RCH Hydraulic Rod Lock | NFPA (inch)
AMLOK's hydraulic rod locks provide power-off clamping for rods and shafts. Designed to clamp components after the motion has stopped, these rod locks securely hold the position of the part as long as the force limits are not exceeded.
For braking applications, contact the factory.
See SITEMA safety devices when the potential for personal injury exists.
