S1900-3 S2100-3 Main Auger Shaft Assembly 4622012506 Equipped with Double Auger Bearing Block Assembly (Dual-Hole) Asphalt Paver Parts

The S1900-3 / S2100-3 Main Auger Shaft Assembly (Part No. 4622012506) 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 the left and right sides across the full paving width, ensuring a stable and uniform material flow ahead of the screed. This contributes to consistent surface smoothness and compaction uniformity. The double auger bearing block assembly (dual-hole) provides rigid support and rotational positioning for the auger shaft ends, bearing the radial and axial loads during material distribution. It is critical to maintaining auger shaft running accuracy and extending shaft service life.
