The 4608112099 auger shaft connecting bushing is designed to join adjacent sections of the auger shaft in the asphalt paver's material distribution system. The auger shaft consists of multiple segmented sections that are connected end-to-end to span the paving width. The connecting bushing fits over the joint between two shaft sections, providing radial support and maintaining concentric alignment as the shaft rotates. This alignment is critical for smooth auger operation, as misaligned shaft sections can cause excessive vibration, accelerated wear on bearings and seals, and uneven material distribution across the screed.
The bushing also functions as a wear sleeve at the shaft joint. As the auger rotates through abrasive asphalt mix, the outer surface of the bushing is exposed to continuous contact with aggregate particles. By serving as a replaceable wear element, the bushing protects the more expensive auger shaft sections from direct abrasive damage, reducing the overall cost of auger system maintenance. The internal bore is machined to a precise diameter that matches the auger shaft, ensuring a secure fit that prevents relative movement between the bushing and shaft during torque transmission.
The 4608112099 auger shaft connecting bushing is manufactured from high-strength alloy steel selected for its combination of toughness, wear resistance, and fatigue strength under torsional loading. The alloy steel is subjected to through-hardening heat treatment to achieve a uniform hardness profile throughout the wall thickness, which is necessary because both the inner bore (in contact with the shaft) and the outer surface (exposed to asphalt abrasion) experience wear. The surface finish of the inner bore is controlled to minimize friction against the auger shaft during assembly and operation.
The bushing wall thickness is dimensioned to provide adequate structural rigidity for torque transmission while allowing for a defined wear margin before replacement is required. All critical dimensions, including inner diameter, outer diameter, length, and wall thickness, are machined to tolerances that match the original equipment specification. This ensures that the bushing installs without modification and maintains the designed shaft alignment in the auger assembly.
The 4608112099 auger shaft connecting bushing is specified for the S1800-3 asphalt paver auger assembly. The S1800-3 is a tracked asphalt paver used in road construction and highway maintenance projects, typically operating at paving widths ranging from standard to extended configurations. The auger system on this paver utilizes segmented shaft sections connected by bushings to accommodate different paving widths and to allow individual section replacement when wear occurs.
Business buyers should verify the part number against the paver's auger assembly parts catalog before ordering, as auger configurations may vary depending on the screed width and production year of the machine. The 4608112099 bushing is positioned at specific shaft joints within the auger assembly, and multiple units may be required per machine depending on the auger configuration.
Replacement of the auger shaft connecting bushing is performed during scheduled auger system maintenance or when the bushing shows excessive wear from asphalt abrasion. The installation process requires disassembling the auger shaft joint, removing the worn bushing, cleaning the shaft surfaces, and pressing or sliding the new bushing into position. Proper installation tools should be used to avoid damaging the bushing bore or the auger shaft during fitting.
After installation, the auger shaft should be rotated manually to confirm free movement and correct alignment. The bushing should be inspected periodically during routine paver maintenance for signs of excessive wear, cracking, or loosening on the shaft. Commercial users operating in high-production paving environments or working with abrasive aggregate mixes may experience shorter bushing service life and should schedule more frequent inspections. Replacing worn bushings at the recommended interval helps prevent damage to the auger shaft sections and maintains consistent material distribution across the screed.

Each 4608112099 auger shaft connecting bushing undergoes dimensional verification of inner diameter, outer diameter, length, and wall thickness before shipment. The heat treatment process is controlled to ensure consistent hardness across production batches, and hardness testing is performed on sample units from each batch. Visual inspection checks for surface defects including cracks, porosity, and machining irregularities. Enterprise customers may request material certificates or dimensional inspection reports for bulk orders.
Standard delivery time is 7-15 working days from order confirmation, subject to order quantity and production schedule. The product is covered by a 6-month warranty from the delivery date, applicable to manufacturing defects in material and workmanship under normal operating conditions. Warranty evaluation requires inspection of the returned component to determine the failure mode. Shipment is arranged from Shanghai Port, China, and commercial users can negotiate freight terms according to their logistics requirements.
The 4608112099 auger shaft connecting bushing is specified for the S1800-3 asphalt paver. Compatibility with other paver models should be verified against the manufacturer's parts catalog, as auger shaft dimensions and bushing specifications vary across different paver models and production years.
The number of connecting bushings depends on the auger configuration and paving width of the S1800-3 paver. Auger assemblies with more shaft sections require additional connecting bushings. Buyers should refer to the paver's auger assembly parts drawing to determine the exact quantity needed for their specific configuration.
Replace the bushing when the outer diameter shows significant wear from asphalt abrasion, when the inner bore becomes loose on the auger shaft, when cracks are visible on the bushing surface, or when auger vibration increases during operation. Excessive bushing wear can lead to shaft misalignment and accelerated wear on adjacent auger components.
The minimum order quantity is one unit. Standard lead time is 7-15 working days from order confirmation. Industrial clients requiring larger quantities should contact the sales team for a production schedule confirmation and bulk pricing quotation.
