HYDRAULIC ACTUATORS & COMPONENTS

 

50/60/80 SERIES LINEAR ACTUATORS

Team Corporation manufactures a variety of actuator types and sizes for varying applications.

 

Our most popular choices are the 50, 60 and 80 Series linear actuators with rectangular bodies.

 

Available in 50 mm, 100 mm, 300 mm, the 50, 60 and 80 Series actuators are produced in a range of dynamic force outputs, from 8.9 to 222 kN.

 

Team specialty servo hydraulic linear actuators are available in sizes up to 4449 kN.

Team Corporation's 50, 60 & 80 Series servo hydraulic linear actuators have distinguished themselves in hundreds of varying applications under demanding operational conditions, and have demonstrated reliability and exceptional performance under the most demanding test environments.

 

All Team Corporation servo hydraulic linear actuators are fatigue rated and require almost no maintenance.

Features

  • One-piece, chrome plated piston rod for high strength and durability

  • Hydrostatic rod support bearings for accurate, frictionless motion and high moment capacity

  • Low pressure, low maintenance rod seals reduce maintenance and downtime

  • Integral dashpots prevent damage to the actuator due to sudden stops

  • Built-in LVDT displacement transducer

  • Rectangular body mountable in either horizontal or vertical orientation for flexible applications.

Applications

  • Vertical and horizontal vibration test systems
    Multi-axis vibration test systems
    Fatigue Test Systems

T-FILM SLIP TABLES

Slip tables are used for horizontal vibration shaker testing.

Often copied, but never duplicated – Team Corporation's unique, patented T-Film bearing system offers an exceptional overturning moment capacity combined with the full low pressure oil support of a granite or journal bearing oil film type slip table.

 

This table system is assembled from a number of modular T-Film bearings.

 

Each bearing measures 300 mm x 300 mm and allows the table to be configured to the customer's test article size and load requirements.

The use of multiple bearings to completely support and guide the slip plate offers excellent dynamic stability and damping for better test results.

 

The design of the T-Film bearing provides a direct load path from the slip plate to the base, and is much more rigid than other guidance systems.

With a standard stroke limit of 62.5 mm and available stroke of up to 300 mm, Team Corporation's T-Film bearings will work with all modern long stroke shaker systems.

Features

  • Very high dynamic load capacity

  • Excellent cross-axis control

  • Outstanding dynamic stiffness

  • Multiple load carrying bearings

  • Low pressure oil system

  • Team hydrostatic bearing design

  • Easy to switch to smaller slip plate Applications

EX SERIES HYDRAULIC ACTUATORS

Team Corporation's EX Series Actuator is a high performance, versatile and cost-effective vibration test system component.

 

EX Series Actuators have been developed specifically for vibration testing and integrated test systems requiring high force, long stroke or high frequency capability.

 

The EX Series Actuator will provide continuous, consistent and reliable test results year after year.

Team Corporation's EX Series Actuators are double acting, double ended, hydrostatically lubricated and designed to be stiff both mechanically and hydraulically.

 

This is achieved by using a heavy body cross-section, a large diameter one-piece piston shaft and by keeping the trapped oil volume to a minimum.

 

The actuator piston is internally supported by a thin film of high-pressure oil, commonly referenced as a hydrostatic bearing.

 

This feature eliminates metal-to-metal contact, providing virtually infinite piston life.

 

o provide position feedback, an LVDT (linear variable displacement transformer) is mounted concentrically within the piston shaft.

Features

  • Internal LVDT

  • Hydraulic Cushions

  • Over 500 Hz. capability

  • Hydrostatic Bearing Supported Piston

  • Fatigue Rated One-Piece Rod & Piston

  • Internal Porting-No External Drain Lines

  • Compatible with Team, MOOG and Industrial Servovalves

  • Low Pressure Seals (No annual teardown / seal replacement)

  • Spherical Bearings and Zero-Backlash Hydrostatic End

  • Connections Available

Applications

  • MAST Tables

  • Load Frames

  • Multi-Axis Systems

  • Seismic Simulation Systems

HEAD EXPANDERS
