The Mechanical Spring Centralizer Type TSR is designed to centralize downhole equipment and to stabilize the hydraulic downhole motors operation in tubing and casing strings. The centralizer is lowered into the borehole using either coil tubing, when doing work using CT units, or tubing strings.
The centralizer shaft is adapted to rotate freely relative to the centering spring mast.
