The BT Series design provides a high over-turning moment and cross-axial restraint. This concept combines a standard slip table assembly with 3,000 psi hydrostatic bearings to provide high dynamic moment restraint while preserving the damping characteristics of an oil film. This system allows testing of heavy products with high centers gravity by reacting moments through the hydrostatic bearings. Cross-axis motion is constrained and is typically less than 10% of input at frequencies up to 2000 Hz. except at resonance. Additional hydrostatic bearings can be supplied to provide extra restraint when testing parameters require a higher overturning moment.

The BT Series Hydrostatic Slip Tables can be configured to any size or shape and are available with any ETS Unibase shaker for any existing single and multi-shaker installation.
