APOLLO S1800-2 Hub Assembly Shaft Assembly for Asphalt Paver S1800-3 S1800-2 S1880

A hub assembly is a critical, pre-assembled component that serves as the heart of a vehicle's wheel rotation system. It functions as the robust interface connecting the wheel to the vehicle's axle, enabling smooth rotation while supporting vehicle weight and handling driving, braking, and steering forces. In modern engineering, it is typically designed as a hub unit assembly—a sealed, maintenance-free module that integrates multiple key components into one ready-to-install unit.

• Weight Bearing: Supports the full vehicle weight on sturdy bearings
• Smooth Rotation: Enables wheel rotation with minimal friction via high-precision, sealed bearings
• Force Transmission: Transmits propulsion force from axle to wheel in drive wheels and handles braking torque
• Mounting Point: Provides secure mounting surface for wheels and brake discs or rotors

A typical hub assembly combines several essential elements into a single, efficient unit:

• The Hub: Central metal flange where wheel studs are mounted
• High-Precision Bearings: Tapered roller or sealed ball bearings for optimal performance
• Sensors: Integrated wheel speed sensors for Anti-lock Braking System (ABS) and traction control
• Seals: Permanent seals to retain lubricant and exclude contaminants like dirt, water, and road salt

The hub assembly is fundamental to safety, performance, and comfort. A high-quality hub ensures:

• Vehicle Stability: Precise wheel alignment and control
• Safety: Reliable braking and proper ABS function
• Durability: Withstands immense stress and harsh environmental conditions
• Convenience: Designed as a single, sealed unit for straightforward diagnosis and replacement

While most commonly associated with automotive wheels, the fundamental principle of hub assemblies applies to various machinery types, including:

• Commercial trucks and trailers
• Industrial machinery and agricultural equipment
• Construction equipment (pavers, rollers, loaders)
