ABSTRACT:
An apparatus for supporting a borescope probe in a gas turbine includes a housing, spaced swivel or washer bearings which receive the stem of the borescope probe, resilient washers disposed between the bearings that receive the borescope stem in close fitting relationship therewith, and a locking collar to selectively urge the bearings toward each other so as to deform the washers into gripping engagement with the borescope stem and frictionally lock the bearings.
