Product description
AB Series Parallel Tube Expander with Bearing
The AB Series is a bearing-mounted version of the A Series for parallel tube expanding without flaring. The integrated bearing reduces friction during the expanding process and ensures smoother, more consistent operation.
Reduced friction increases the tool's lifespan. The AB Series is particularly suitable for high-production series applications on heat exchangers, condensers, boilers, and air preheaters where a reliable and repeatable expanding process is required.
Application and Advantages
- bearing-mounted parallel tube expander for non-flaring applications
- reduced friction for smoother and more consistent expansion cycles
- longer tool life due to reduced mechanical stress
- suitable for heat exchangers, condensers, boilers, and air preheaters
- robust design with self-retained rollers in a cage
- especially suitable for high-production series and maintenance work
