DSS Tools - Model RAC-10 -1-11/16Inch Five Arm End Roller Centralizer
FromDSS Tools
RAC-10 is a 1-11/16″, 5-Arm roller centralizer designed specifically for cased-hole operation. The 5-arm configuration lends itself to better centralization in the borehole which makes this centralizer ideal to maintain logging tools accurately centred in vertical, deviated, or fully horizontal wells. The RAC-10 can be built with standard GO, or reverse-GO (for ex. Sondex) ends. The centralizer collapses completely to 1-11/16″ diameter to allow it to go through downhole restrictions. The wheels and axles are hardened for longer service life.
