GT Series oil film tables are designed with general-purpose V-Groove bearings, combined with a magnesium or aluminum slip plate. Oil is supplied through portholes in the granite slab and is dispersed throughout the underside of the slip plate. The oil film provides a low friction surface, a damping medium for restraint of resonances, pitch and roll moments. Yaw restraint is provided by the V-groove guide bearings combined with the armature guidance system.

GT Series guide bearings are primarily designed for use with ETS Unibase shakers but are available for any existing or new shaker.
