CentraMax is Antelope’s newest centralization solution, available in two configurations: Standard and Close Tolerance (CT). Made from a single piece of 4130, heat-treated steel, the CentraMax sports a lower cost per unit than the alternatives and an unbeatable failure rate. All CentraMax products are backed by our industry-leading, real-time customer support, combined with state-of-the-art placement, T&D and surge software, making them your best choice for dependable centralizer performance.

CentraMax Standard

The CentraMax Standard is a highly versatile centralizer, suited for standard, high angle, extended reach and horizontal wells. Our experienced engineers have calculated the perfect downhole program to maximum the CentraMax’s stand-off capability, which provides low flow-area encroachment and ECD. The CentraMax’s ability to be installed directly onto the casing helps you manage casing string changes and eliminates the need to manage and warehouse supplementary inventory.

CentraMax CT

CentraMax CT is Antelope’s line of close tolerance, single piece centralizers for centralizing the liner in the wellbore. The CT line includes the RT1 and PT1 models that offer different bow geometries, allowing you to choose the design you need to reduce starting forces in any given well. Both variations are cold-formed and then heat-treated for ultimate durability, and easily installed on-site.

CentraMax RT1

The RT1 is a close tolerance centralizer that provides operators a technically superior alternative to in-line centralizer subs. It is pulled in both directions using either a WearSox or MCC band inside the centralizer between end collars, leaving the RT1 free to rotate.


    • Extremely low friction and coefficient levels
    • Single piece of steel means no welds on bows for enhanced integrity


The unique design prevents the anchoring device from getting underneath in interface between the bows and the end collars, increasing safety and maximizing performance.


CentraMax PT1

Unique to the market, this centralizer option for ultra-close tolerance applications allows the centralizer to be pulled both in and out of the restriction with specially designed windows in the end collars.


    • Decreases RIH time
    • Multiple units per casing joint can be installed as needed


Anchored to the casing via one of Antelope’s unique proprietary technologies–either the WearSox thermal spray metal or MCC mechanically bonded stops–the PT1 guarantees an excellent cement job.
