Hydrostatic Testing Actuators

Product catalog summary

Range of Application: The LH series actuators are engineered for high-performance dynamic material and component testing, suitable for high-frequency applications and high piston speeds. They are designed to handle side loads and bending moments effectively. The rated force is achieved at internal cylinder pressures of 265 or 195 bar.

Advantages/Features:

Designed to meet high standards of servo-control systems.
Hydrostatic bearings ensure friction-free operation and high side load capacity.
Synthetic coating provides additional protection against excessive lateral forces.
Integral LVDT displacement transducer with 0.25% linearity.
Hysteresis-free operation.
Hydraulic end cushions protect against end-cap impacts.
Easy and rigid mounting with head and foot interfaces.
Available in standard or custom configurations.

Product Specifications: The document lists various actuator models with specifications such as cylinder stroke, nominal force, and servo valve manifold flow rates. For example, the BPS-LH0010.21.00 model has a stroke of 100 mm and a nominal force of ±10 kN with a flow rate of 65 l/min.

Accessories: The document details additional components like accumulator sets, servo valve mounting blocks, and a drain oil suction pump. Accumulator sets vary in pressure line and return line capacities, with system pressures of 210 or 280 bar. Servo valve mounting blocks support maximum rated flows of 65 or 130 lpm.

Further Accessories: Includes hydraulic accumulator units, servo valves, manifolds, and connection units.
