Bucking Units

9-5/8 Bucking Unit

The Universe line of innovative and compact Bucking Units are designed to safely and efficiently make up & break out pipes horizontally for pipe yards, etc. Ruggedly engineered and tested to exceed today’s tough requirements, Universe Bucking Units provide economical solutions for pre-assembling couplings & pipe to specified torque in a controlled environment. See sizes and specifications below.

Torque Speed Control

  • Two position hi-low using a high-efficient hydraulic vane motor

Radial Load Eliminator

  • Eliminates radial load on the joint which causes torque to be lost and axial twist through the joint which may result in cross threading damage.

Bi-Directional Compression Load Cell System Option

  • Two load cells which enable the operator to measure torque in both directions.

Dual Size Capability

  • On the 9-5/8 in model and larger the backup system incorporates a dual jaw position, which makes the backup capable of biting the casing and the coupling with the same jaws.
