The LG9716220005+190/1 bearing delivers exceptional radial load capacity, high rotational speed capability, and reliable performance under extreme operating conditions. Manufactured from high-quality bearing steel (GCr15 or equivalent) with precision-ground raceways, controlled roller geometry, and a C3 internal clearance classification, this bearing reduces friction, minimizes heat generation, and ensures smooth, dependable operation throughout its service life.
The LG9716220005+190/1 NJ306EN/C3 cylindrical roller bearing is essential for maintaining proper shaft support and rotational accuracy in your HOWO truck’s transmission, auxiliary box, or other driveline components. A worn or damaged bearing can lead to increased noise, vibration, shaft misalignment, and catastrophic component failure. This genuine OEM bearing restores precise rotational performance and ensures your truck operates reliably.
OEM direct replacement • High-quality bearing steel • C3 clearance • High radial load capacity • EN design (with snap ring groove)
The LG9716220005+190/1 bearing is an NJ-type cylindrical roller bearing with the EN designator (indicating an outer ring with a snap ring groove) and C3 internal clearance classification. This bearing is commonly used in SINOTRUK Howo transmissions, auxiliary boxes, and other driveline applications where high radial loads and moderate axial loads are present. Its OEM-grade construction precisely matches the original bearing’s dimensions, load ratings, and operating characteristics.
The bearing consists of a solid outer ring with a snap ring groove (EN design), a separable inner ring with integral flanges (NJ type), and a full complement of precision-ground cylindrical rollers. The rollers are guided by the inner ring flanges, providing high radial load capacity and the ability to accommodate limited axial displacement. The C3 clearance ensures the bearing can handle higher speeds and thermal expansion without binding.
The LG9716220005+190/1 bearing is manufactured from high-carbon chromium bearing steel (GCr15 or equivalent) with a uniform hardness of HRC 60-65 across all rolling elements and raceways. The raceways are precision-ground to achieve excellent surface finish and geometric accuracy, reducing friction and extending bearing life. The rollers are precision-profiled to optimize load distribution and minimize stress concentrations.
Common symptoms of a failing bearing include excessive noise (whining, rumbling, or grinding), increased vibration, elevated operating temperatures, and visible wear on the rolling elements or raceways. Replacing a worn bearing with the LG9716220005+190/1 restores smooth, quiet operation and protects the transmission or driveline from further damage.
Whether you’re performing a transmission overhaul or replacing a failed bearing, the LG9716220005+190/1 NJ306EN/C3 Cylindrical Roller Bearing offers the quality, precision, and durability that SINOTRUK Howo owners and technicians demand.
The LG9716220005+190/1 NJ306EN/C3 cylindrical roller bearing is specifically designed for SINOTRUK Howo A7 and T7H series transmissions, auxiliary boxes, and related driveline components. It serves as a direct replacement for the original bearing and is compatible with a wide range of transmission models, including the JS85T and other manual gearboxes used in HOWO heavy-duty trucks.
This bearing is typically used to support shafts in gearboxes, transfer cases, and auxiliary drive units where high radial loads and moderate speeds are encountered. Its C3 clearance makes it particularly suitable for applications where temperature variations or high-speed operation require additional internal clearance to prevent seizure.
When replacing a bearing, it is critical to inspect the shaft and housing for wear or damage. The LG9716220005+190/1 is designed to match the factory specifications, including the snap ring groove in the outer ring (EN design) for axial retention. This simplifies installation and ensures proper location within the housing.
For fleets with multiple HOWO trucks equipped with similar transmissions, this bearing standardizes driveline repairs, simplifying inventory and ensuring the correct part is available for scheduled maintenance or emergency repairs. Always verify the bearing location and shaft size on your specific transmission, though the LG9716220005+190/1 is the standard NJ306EN/C3 bearing for the majority of A7 and T7H driveline applications.
Replacing the LG9716220005+190/1 cylindrical roller bearing requires careful attention to cleanliness, alignment, and proper installation techniques. This work should be performed by a qualified technician with the appropriate bearing installation tools, such as bearing heaters, induction heaters, and hydraulic or mechanical press equipment.
Begin by disassembling the transmission or component to access the bearing location. Carefully remove the old bearing using a suitable puller or press, ensuring that the shaft and housing are not damaged. Clean the shaft and housing thoroughly with a solvent and lint-free cloth, removing all old lubricant, debris, and burrs.
Inspect the shaft for wear, scoring, or out-of-roundness. If the shaft is damaged, it must be replaced or repaired before installing the new bearing. Verify that the snap ring groove in the housing (for the EN design) is clean and undamaged. The C3 clearance bearing should be installed with the correct fit (typically interference fit on the inner ring and clearance or light interference on the outer ring).
Heat the bearing or cool the shaft as needed to facilitate installation. Slide the bearing onto the shaft (or into the housing) using a press with the appropriate tools, ensuring that the bearing is fully seated against the shoulder. Never hammer directly on the bearing rings. Install the snap ring securely into the outer ring groove to axially locate the bearing. Lubricate the bearing with the recommended transmission or gear oil before reassembly.
For maintenance, regular transmission fluid changes at manufacturer-recommended intervals help protect the bearing from contamination and wear. Monitor for unusual noise or vibration, which may indicate bearing wear. The LG9716220005+190/1 is designed for long service life, but proper lubrication and early detection of issues are key to preventing major driveline damage.
The LG9716220005+190/1 NJ306EN/C3 cylindrical roller bearing is manufactured in an ISO 9001 and ISO/TS 16949-certified facility using advanced grinding, honing, and assembly processes. The bearing steel is sourced from certified mills and undergoes rigorous chemical analysis and purity testing to ensure it meets the GCr15 specification.
Every bearing undergoes comprehensive quality checks, including dimensional verification of all critical dimensions (inner diameter, outer diameter, width, and snap ring groove), raceway roundness and surface finish measurement, and roller geometry inspection. Hardness testing is performed on both the rings and the rollers to ensure a consistent HRC 60-65 range. Random samples from each batch are subjected to life testing and load rating verification to confirm performance.
