EK Series
EK / EKL Adjustable Hydraulic Shock Absorbers
Adjustable hydraulic shock absorbers with standard EK and low-speed EKL variants for changing payload, velocity and force conditions.
Selector eligible absorber series
Working principle
Turning the adjustment knob changes the effective orifice area, increasing or decreasing damping force while oil flow controls deceleration.
Construction
Piston rod, bearing, piston head, oil chamber, check valve or check ring, foam accumulator, adjustment cam or ball, and threaded cylinder.
Applications
Cylinder-driven, motor-driven and inertia-load machinery where tuning is required.
