Slip Tables

Vibration testing requirements commonly call for horizontal position testing, and with that many shakers are built with slip tables to facilitate these testing needs. Sentek Dynamics offers mono-base and stand-alone slip tables for vibration testing in low and high-pressure designs in standard sizes ranging from 300 mm (12 inches) to 2500 mm (98 inches). Custom sizes are also available including expandable slip tables when a larger mounting area is occasionally required.

In a mono-base configuration, the shaker and slip table share a structural steel body that enables rapid conversion between vertical and horizontal positions, and the accurate alignment of the shaker relative to the slip table when rotated to the horizontal position. 

In a stand-alone configuration, the slip table is mounted on an independent steel platform supported by leveling feet that allows any vertical shaker from Sentek Dynamics or other manufacturer to couple with the slip table assembly.

LST Series – Sentek Dynamics’ low-pressure LST Series slip tables provide an affordable solution to horizontal vibration testing requirements. LST Series slip tables utilize V-groove bearings to guide the magnesium slip plate over an oil-film on a precision ground granite slab.  Oil from an integral hydraulic power supply is dispersed through ports in the granite slab under the magnesium slip plate.

  • Affordable solution for horizontal vibration testing

  • Integral hydraulic pump, reservoir, and filter

  • Option available to order systems tested and assembled from Kannapolis, North Carolina (USA). Contact sales for details.

HST Series – Sentek Dynamics’ high-pressure slip tables utilize T-slot bearings designed for testing heavy payloads with a high center of gravity. The HST Series provides the highest resistance to pitch, roll, and yaw over-turning moments.

  • Optimum solution for testing heavy payloads with a high center of gravity

  • Separate hydraulic power supply and oil cooler

  • More reliable than hydrostatic journal bearings

  • Lower maintenance costs over an extended period

  • Option available to order systems tested and assembled from Kannapolis, North Carolina (USA). Contact sales for details.
