CentraMax® Close Tolerance Centralizer Subs 
This unique one-piece centralization solution is made from a single piece of 4130 heat-treated steel.
The CentraMax Centralizer Sub includes the RT1, PI1 and PT1 models offering different bow geometries, allowing you to choose the design you need to reduce starting and running forces in any well. Our centralizer product line is cold-formed and then heat-treated for ultimate durability, and easy on-site installation.
These non-welded, close tolerance centralizer subs yield superior mechanical integrity and provide an extremely low coefficient of friction. Multiple units per casing joint can be installed as needed. Anchored using proprietary WearSox Thermal Spray Technology.
CentraMax® Close Tolerance Centralizer Subs
RT1, Rotating Technology
This close-tolerance centralizer is designed to be pulled and reciprocated in both directions, thanks to an internally machined integral sub-body anchor that allows for free rotation. The innovative design ensures that the internal anchor does not get trapped beneath the bows and end collars, enabling the bows to compress fully. This feature enhances the tool's safety and performance.
PI1, Push-In Technology
This specialized centralizer option is designed for ultra-close tolerance applications, allowing the centralizer to be pushed and reciprocated easily in and out of restrictions. It features specially designed bows and can rotate freely.
PT1, Pull-Through Technology
This centralizer option is unique in the market and is designed for ultra-close tolerance applications. It allows the centralizer to be pulled and reciprocated in and out of restrictions via specially designed "window" openings in the centralizer's end collars. These collars are secured with integral machined sub-body anchors.
