The 6554100022 Center Bearing is a precision-engineered driveline support component designed to securely mount and dampen the intermediate shaft of the propeller shaft system in SINOTRUK Howo heavy-duty trucks. As a premier supplier of genuine Sinotruk howo parts, we offer this center bearing as a direct OEM replacement, manufactured to the original equipment’s exacting standards. The bearing features a high-capacity ball bearing unit housed in a robust rubber-isolated bracket, providing excellent radial support, vibration isolation, and long-term durability under the extreme torsional loads, rotational speeds, and harsh environmental conditions typical of heavy-duty trucking.
This center bearing (OEM 6554100022) is critical for maintaining proper driveshaft alignment, reducing vibration, and preventing premature wear of U-joints and other driveline components. Its self-aligning design compensates for minor shaft misalignment, while the durable rubber element absorbs driveline harmonics. The 6554100022 is built to endure the rigors of long-haul transport, off-road operations, and severe environmental exposure, delivering dependable service over thousands of miles.
OEM direct replacement • High-capacity ball bearing • Rubber-isolated bracket • Self-aligning design
The 6554100022 Center Bearing is a critical component of the propeller shaft support system, responsible for supporting the intermediate shaft section and reducing driveline vibration and noise. Engineered for SINOTRUK Howo trucks, this bearing assembly is a direct OEM replacement that guarantees correct fit, smooth operation, and long service life. Manufactured to the original specifications, it ensures a seamless integration with the existing driveshaft and chassis mounting points.
The assembly consists of a high-quality ball bearing unit with a self-aligning spherical outer ring, which is pressed into a heavy-duty steel bracket. The bracket is bonded to a durable rubber isolation element that absorbs driveline vibrations and compensates for minor shaft misalignment. The bearing is pre-lubricated with high-temperature grease and sealed to prevent contamination. The bracket features accurately positioned mounting holes for bolting to the vehicle chassis crossmember, ensuring a rigid yet damped support.
This center bearing is essential for maintaining smooth and quiet driveline operation, preventing excessive shaft runout, and extending the life of U-joints and differential components. Its robust construction and precise engineering guarantee reliable performance over extended service intervals, meeting the rigorous demands of heavy-duty trucking. It is the direct replacement you can trust to keep your SINOTRUK Howo’s driveline running smoothly and efficiently.
The 6554100022 Center Bearing is specifically designed for SINOTRUK Howo heavy-duty trucks, including Howo A7, T7H, T5G, and other models with a two-piece or three-piece propeller shaft requiring a center support bearing. It is compatible with the standard 35 mm shaft diameter and the original chassis mounting bracket, making it the ideal replacement for restoring smooth driveline operation.
This bearing is suitable for a wide range of applications, including long-haul trucking, regional distribution, construction, mining, and agricultural operations. Its robust construction and vibration-isolating design ensure reliable support even under sustained heavy loads and extreme operating conditions.
When replacing, always verify the shaft diameter and mounting hole spacing to ensure a perfect match. The 6554100022 is a direct-fit component that simplifies maintenance and restores original driveline support.
Installing the 6554100022 Center Bearing requires proper tools and attention to alignment. Begin by safely lifting the vehicle and supporting the propeller shaft. Mark the shaft and U-joint positions for reassembly. Remove the old center bearing from the crossmember, taking note of any spacers or shims. Clean the mounting area thoroughly.
Install the new bearing assembly onto the propeller shaft, ensuring the bearing is correctly positioned at the specified distance from the front U-joint. Secure the bracket to the crossmember using the original bolts, and torque them to the manufacturer’s specification (typically 60–80 N·m). Reconnect the shaft and check that the bearing is properly aligned and the rubber isolator is not preloaded. Lower the vehicle.
After installation, test drive the vehicle to confirm that vibration and noise are eliminated. Regular maintenance includes periodic inspection of the bearing for signs of wear, play, or rubber deterioration. If the bearing becomes noisy or the rubber isolator shows cracks, replace the assembly promptly. This bearing is sealed and pre-lubricated, so no greasing is required during normal service life.
With correct installation and regular checks, this center bearing will provide years of trouble-free service.
This center bearing assembly is manufactured in an ISO 9001-certified facility using premium bearing components and high-grade rubber compounds. The bearing is sourced from leading suppliers and tested for radial play, noise, and rotational smoothness. The rubber isolator is bonded to the steel bracket using advanced vulcanization processes to ensure long-term adhesion and damping performance.
Every assembly undergoes 100% dimensional verification, including shaft diameter, bracket hole spacing, and overall alignment. We also perform dynamic balancing tests and vibration analysis on random samples to confirm that the bearing meets OEM noise and vibration standards. The steel components are zinc-plated and tested for corrosion resistance.
Our commitment to quality ensures a center bearing that delivers smooth, quiet driveline operation, reducing maintenance costs and extending component life. Backed by a comprehensive warranty, this bearing offers peace of mind for fleet operators and owner-operators.
