What is the Sitrak Rear Hub Assembly

  • The Sitrak Rear Hub Assembly is a robust and high – performance component engineered to ensure the reliable operation of heavy – duty vehicles. As a critical part of the drivetrain, this assembly plays a pivotal role in connecting the rear wheels to the vehicle’s axles, facilitating smooth power transfer and providing essential support under heavy loads.
  • At the core of the assembly is the Rear Hub, a sturdy structure crafted from high – grade materials to withstand extreme mechanical stress and environmental conditions. The hub is designed to securely hold the rear wheel in place, and it features precisely drilled holes for the Wheel bolts M22X1.5X114. These high – strength bolts, with their 22mm diameter, 1.5mm pitch, and 114mm length, provide a tight and vibration – resistant connection, ensuring that the wheel remains firmly attached even during high – speed travel or on rough terrains.
  • To support the rotational movement of the wheel, the assembly incorporates Tapered roller bearing 33220 and Tapered roller bearing 32222. These bearings are engineered to handle both radial and axial loads, reducing friction and wear while maintaining smooth wheel rotation. Their precision – manufactured design ensures optimal alignment and minimal play, contributing to the overall stability and longevity of the rear wheel assembly.
  • The Oil retaining disk and Oil retaining cover work in tandem to safeguard the internal components of the hub. The oil retaining disk helps to keep lubricating oil within the hub, ensuring that the bearings and other moving parts are adequately lubricated. The oil retaining cover, on the other hand, provides an additional layer of protection, preventing dust, dirt, and moisture from entering the hub and potentially causing damage to the internal components.
  • The Shaft seal and Seal ring(232×249×10) are essential for maintaining the integrity of the hub assembly. The shaft seal prevents oil leakage from the hub, while the seal ring, with its dimensions of 232mm in outer diameter, 249mm in inner diameter, and 10mm in thickness, creates a tight seal between different parts of the assembly. This helps to keep contaminants out and ensures that the hub operates efficiently under various operating conditions.
  • In summary, the Sitrak Rear Hub Assembly is a testament to precision engineering and durability. With its high – quality components, including the rear hub, wheel bolts, tapered roller bearings, and sealing elements, it offers exceptional performance, reliability, and longevity. Whether for long – haul transportation or heavy – duty construction applications, this rear hub assembly is designed to meet the rigorous demands of modern commercial vehicles, providing peace of mind to operators and fleet managers alike.
