OBS Bow Spring Centralizer

OBS Bow Spring Centralizer

The OBS single piece, bow spring centralizer has been developed as a solution for markets that don’t currently benefit from Centek technology.

The unit is decreased in height when compared to Centek premium models but maintains restoring force to meet the needs of less demanding wells, while the blade strength retains excellent stand-off. 

Features and benefits

  • For use in vertical, deviated and horizontal wells
  • Low start and running forces
  • Flexible
  • Good stand-off
  • High restoring force
  • Testing exceeds API 10D standards

Flex rating

We grade our centralizers using a rating of flexibility. On a scale of 0-8, the OBS has a flex rating of 4.


Available to suit casing sizes ranging from 4 1/2" to 20”.
