The Rear Wheel Hub Assembly is designed to withstand high radial and axial loads, ensuring smooth wheel rotation and reliable braking performance. Its robust construction and precision-engineered components contribute to the overall safety and efficiency of the vehicle, making this Rear Wheel Hub Assembly an essential part of the truck’s driveline.
The Rear Wheel Hub is the central component of the Rear Wheel Hub Assembly, providing the mounting surface for the wheel and brake disc. It is precision-machined from high-strength ductile iron, featuring a tapered roller bearing seating and a flange for wheel attachment. In the Rear Wheel Hub Assembly, this hub ensures accurate wheel alignment and smooth rotation, supporting the vehicle’s weight while transmitting driving and braking forces to the wheels.
Its robust construction and corrosion-resistant coating guarantee long-term durability even under the harshest operating conditions.
These high-strength wheel bolts secure the wheel to the rear hub. In the Rear Wheel Hub Assembly, they are manufactured from grade 10.9 alloy steel with a zinc-nickel coating, providing exceptional tensile strength and corrosion resistance. The M22X1.5 thread and 82mm length are precisely matched to the C7H wheel and hub configuration, ensuring proper thread engagement and clamping force. These bolts are critical for maintaining wheel retention and safety, and they are designed to withstand the high torque loads encountered during operation.
The Wheel Hub Bearing Unit is a pre-assembled, maintenance-free bearing that supports the rear hub. In the Rear Wheel Hub Assembly, it features a double-row tapered roller design that provides high radial and axial load capacity. The unit is factory-lubricated with high-performance grease and sealed to prevent contamination, ensuring long service life and consistent performance. Its precise internal geometry and preload setting eliminate the need for manual adjustment during installation, reducing assembly time and the risk of errors.
The O-ring provides a static seal between the hub and the axle housing, preventing lubricant leakage and contaminant ingress. In the Rear Wheel Hub Assembly, it is made of high-temperature FKM rubber with a hardness of 70 Shore A, ensuring a reliable seal even under extreme temperature fluctuations and pressure variations. Its precise cross-section and diameter guarantee a perfect fit in the machined groove, maintaining the integrity of the lubricant within the hub.
The ABS Tone Ring is a toothed wheel that provides the wheel speed signal to the ABS sensor. In the Rear Wheel Hub Assembly, it is pressed onto the hub and features a precision-machined tooth pattern that is read by the sensor to determine wheel speed. This information is critical for the anti-lock braking system and traction control, ensuring safe and stable braking performance. The tone ring is manufactured from corrosion-resistant steel to withstand the harsh under-vehicle environment.
The Nameplate is a durable identification tag that provides essential information about the Rear Wheel Hub Assembly, including part numbers and specifications. In the Rear Wheel Hub Assembly, it ensures traceability and aids in maintenance record-keeping, helping technicians quickly identify the correct replacement components when needed.
The Rear Wheel Hub Assembly is built with high-strength ductile iron and alloy steel components, ensuring exceptional durability and load-bearing capacity. This robust construction guarantees reliable performance over millions of kilometers, reducing the need for frequent replacements.
This Rear Wheel Hub Assembly includes every component needed for a full wheel-end replacement – the hub, bearing unit, bolts, O-ring, ABS tone ring, and nameplate. No additional parts are required, simplifying installation and ensuring compatibility.
The pre-assembled wheel hub bearing unit is factory-lubricated and sealed, eliminating the need for manual greasing or adjustment. This reduces maintenance costs and downtime, ensuring that the Rear Wheel Hub Assembly remains reliable throughout its service life.
The Rear Wheel Hub Assembly is manufactured to the exact OEM specifications, guaranteeing a perfect fit on the Sitrak C7H. The precision-machined hub and correctly sized components ensure a hassle-free installation, reducing downtime and labor costs.
