Atlas Copco Airbac Hydraulic Bolt Tensioner

Name: Atlas Copco Airbac Hydraulic Bolt Tensioner
Brand: Atlas Copco

A precise hydraulic solution for controlled bolt tensioning across multiple thread sizes.

Atlas Copco Airbac Hydraulic Bolt Tensioner

Atlas Copco Airbac is a family of hydraulic bolt tensioners built for accurate, consistent, and clean tensioning in industrial bolted joints.

The series is selected by thread size and required model, making it a practical fit for assembly and maintenance tasks where controlled load is essential.

Key Features

Controlled hydraulic tensioning: The tools are designed for bolt tensioning through precise hydraulic action.
Wide thread-size coverage: The family includes models for different metric and imperial thread sizes to suit varied joints.
Clear model structure: The range includes AB-01 through AB-06, making model selection straightforward.
Built for industrial work: This is a solution intended for assembly and maintenance environments that demand consistent bolted connections.
Select by thread configuration: You can choose a model by thread type, such as M20 x 2.5, M24 x 3, or 1 1/4″.

Frequently Asked Questions

How do I choose the right Airbac model?
Step 1: Identify the thread size of the bolt or stud.
Step 2: Match that thread to the model range that supports it.
Step 3: Confirm the correct ordering number and series version for the application.

Does the series cover both metric and imperial threads?
Yes.
The family includes models for metric sizes such as M20 x 2.5, as well as imperial sizes such as 3/4″ and 1 1/4″.

How do I know whether to choose AB-01 or AB-02?
Choose based on the thread diameter and the specific joint.
AB-01 covers a smaller thread range, while AB-02 covers a larger one.

What is the difference between AB-03, AB-04, AB-05, and AB-06?
Each model covers different thread sizes within the family.
Match the model to the exact joint size used in the application.

Is this suitable for assembly and maintenance work?
Yes.
Hydraulic bolt tensioners are especially suitable for industrial applications that require uniform and controlled bolt tensioning.

What should I check before ordering?
Confirm the thread size, the correct model, and the appropriate ordering number.
That helps avoid mismatches with the joint.
