Model 1620 Compressibility Machine

Model 1620 Compressibility Machine

The Model 1620 Compressibility Test Machine provides a complete workstation to evaluate the compressibility of friction materials at ambient and elevated temperatures up to 600 °C. It is offered with either a pneumatic or hydraulic actuation system and conforms to U.S. and worldwide testing requirements. The hydraulic machine provides increased control accuracy and response. Both machines provide excellent precision and repeatability to measure deflection in microns, with consistent measurements over thousands of samples.

Model 1620-H Compressibility Machine

Model 1620-H Compressibility Machine

The Hydraulic Model 1620-H Compressibility Machine utilizes a hydraulic oil input control force versus pneumatic. The stiffer hydraulic oil provides increased control accuracy and response. The loading block has been redesigned as a lightweight component lowering the pre-load threshold.

SRA Series Spinning Rotary Actuators

SRA Series Spinning Rotary Actuators

The SRA Series Spinning Rotary Actuator is used for applying torque in 4-square applications. It consists of a double vane type hydraulic rotary actuator and a rotary coupling to communicate hydraulic fluid to the actuator while it is spinning.

Hydrostatic Bearing Actuators

Hydrostatic Bearing Actuators

Hydrostatic bearings are used to support the piston rod which creates an actuator with extremely high side load capabilities. This is possible because the hydrostatic bearing is “self- compensating” in that the hydraulic forces will change to counteract any side-load and maintain consistent lubrication to the rod bearing assembly. This results in a very low friction actuator, for very high speed and high frequency capabilities, in addition to its high side loads resistance. The bearings are designed for minimal frictional losses, with less than 5 lbs. of force being required to move the actuator at 3000 PSI 

LCA Linear Servo-Rated Actuator

LCA Linear Servo-Rated Actuator

LINK offers a line of servo-rated actuators designed for smooth operation and a seamless fit into static or low-frequency testing applications. These actuators incorporate specific features typically provided by fatigue rated actuators such as LINK’s LPA line. This line of actuators provides the precision control you have come to expect from LINK, but is a more economical option than fatigue rated LPA actuators.

Computer Controlled Hydraulic Impulse Hose Testing Machine

Hydraulic Impulse Hose Testing Machine

Using a proven concept, LINK has refined this hose testing machine to provide unparalleled safety and performance. The machine interface allows the operator to quickly set up tests, calibrate the system, and run stored test files. A vented chamber eliminates the possibility of an explosion from the buildup of test fluid vapors in the environmental chamber. Performance is enhanced by using a robust intensifier with a built-in servo valve. The built-in servo valve improves performance by increasing the natural frequency of the system. A special valve with lower hysterysis and threshold provides higher accuracy than a standard flapper-nozzle valve in this pressure control application.

Structural Load Frame

Structural Load Frames

The Structural Load Frames, a two-column design load unit, is a rigid device used to perform tests on components. The adjustable crosshead allows for the insertion of environmental chambers, and gives a large working range for various specimen and fixtures.

Fatigue Rated Rotary Actuator

Fatigue Rated Rotary Actuators

The intent of the test system determines the actuator requirements and LINK engineers can help you determine the optimal solution for your application. The typical system utilizes flexure mounts to permit slight amounts of axial displacement caused by thermal expansion and length changes in the specimen. Sometimes the specimen incorporates enough degrees of freedom and flexure mounts result in an under defined system. LINK offers rigid mount actuators and brackets for these situations.

LPA Fatigue Rated Actuator

LPA Fatigue Rated Actuators

The LPA Fatigue Rated Actuator is designed to fit your particular application. It is strong and durable, and typically includes the following accessories:

LHA Post Actuator

LHA Fatigue Rated Hydrostatic Bearing Actuators

The LHA series actuator is intended for very demanding testing applications where the actuator is subjected to:
