4622012507 Main Auger Shaft Assembly with Double Bearing Housing Assembly for S1900-2 Asphalt Paver

Main Auger Shaft Assembly is a core drive and support component of the paver’s auger system. It is installed in the auger area at the rear of the paver, in front of the screed. The main auger shaft runs transversely and is driven by the central drive box or side motors, with both ends supported by bearing housing assemblies.

Its function is to distribute the asphalt mixture delivered by the conveyor continuously and evenly from the center to both left and right sides across the full paving width, ensuring a stable and uniform material flow ahead of the screed, thereby contributing to consistent surface smoothness and compaction uniformity. The double bearing housing assembly provides rigid support and rotational positioning for the auger shaft ends, bearing the radial and axial loads during material distribution, and is critical to maintaining auger shaft running accuracy and extending shaft service life.
