The SPWL0000000211 Bearing NJ307EV is a precision cylindrical roller bearing designed to handle heavy radial loads and moderate axial loads in high-speed driveline applications. As a leading provider of genuine Sinotruk Homan parts, we offer this bearing as a direct OEM replacement for SINOTRUK Homan transmissions, gearboxes, and axle assemblies. The SPWL0000000211 features a robust cage-guided roller set, precision-ground raceways, and optimized internal geometry, delivering exceptional load capacity, low friction, and extended service life under the most demanding operating conditions.
This bearing is manufactured from high-quality bearing steel, case-hardened and tempered to achieve an optimal balance of toughness and wear resistance. Its separable design allows for independent mounting of inner and outer rings, simplifying assembly and maintenance. The NJ307EV designation indicates a single-row cylindrical roller bearing with a cage, suitable for high-speed operation and capable of accommodating axial displacement in one direction. The SPWL0000000211 is engineered to withstand shock loads, vibration, and thermal expansion, making it an ideal choice for the heavy-duty environments typical of SINOTRUK Homan trucks.
OEM direct replacement • Cylindrical roller design • High radial load capacity • Precision ground raceways
The SPWL0000000211 is a single-row cylindrical roller bearing of the NJ design, featuring a cage that guides the rollers and two integral flanges on the outer ring. This configuration allows the bearing to accommodate both radial loads and limited axial loads in one direction, while also permitting axial displacement of the shaft relative to the housing. Such flexibility is essential in applications where thermal expansion or shaft misalignment may occur.
The bearing’s rollers are precision-ground to ensure uniform diameter and surface finish, minimizing friction and heat generation. The raceways are superfinished to a mirror-like quality, promoting the formation of a stable elastohydrodynamic lubricant film. The cage is made from pressed steel or high-strength brass (depending on the variant), providing accurate roller spacing and reducing wear during high-speed operation.
Manufactured to the exacting standards of SINOTRUK Homan original equipment, the SPWL0000000211 guarantees consistent fit and function. Its robust construction and high-quality materials provide exceptional durability, making it a preferred choice for critical applications such as mainshafts, layshafts, and pinion supports in heavy-duty transmissions and differentials.
The SPWL0000000211 bearing NJ307EV is specifically engineered for SINOTRUK Homan heavy-duty trucks, including Howo A7, T7H, and the Homan series. It is used in transmission mainshafts, auxiliary gearbox shafts, and differential pinion supports, where its high radial load capacity and compact dimensions are essential.
This bearing is also compatible with many other commercial vehicle and industrial applications that require a 35x80x21 mm cylindrical roller bearing. It is commonly found in agricultural machinery, construction equipment, and industrial gearboxes, where reliable rotation under heavy loads is critical.
When replacing, verify the shaft and housing tolerances to ensure proper fit. The SPWL0000000211 is a direct replacement that simplifies inventory management and reduces installation time.
Proper installation of the SPWL0000000211 is essential for achieving full performance. Begin by thoroughly cleaning the housing bore and the shaft, removing all dirt, rust, and old lubricant. Inspect the shaft and housing surfaces for scoring or wear; if damaged, they must be reconditioned or replaced.
Due to its separable design, the inner ring with rollers and cage can be mounted on the shaft separately from the outer ring. This simplifies installation, especially in tight assemblies. Apply a thin, even layer of clean grease or oil to the rollers and raceways before assembly. Press the inner ring onto the shaft using a suitable tool, ensuring it is squarely seated against the shoulder.
After installation, check for smooth rotation and verify that the axial clearance is within the manufacturer’s recommended range. Regular maintenance includes periodic inspection for abnormal noise, vibration, or temperature rise. If any signs of wear or spalling are detected, replace the SPWL0000000211 immediately. Relubrication intervals should follow the vehicle manufacturer’s recommendations.
Always use the correct grade of lubricant and avoid contamination during maintenance. With proper care, this bearing will provide long, trouble-free service.
The SPWL0000000211 is produced in an ISO 9001-certified facility, adhering to the most rigorous quality standards. The steel is sourced from approved mills and undergoes spectrographic analysis to verify composition. Heat treatment is precisely controlled to achieve the optimal balance of hardness and toughness.
Every bearing is 100% inspected for critical dimensions, including bore diameter, outer diameter, width, and roller roundness. We also perform random dynamic testing to confirm load ratings and fatigue life. The raceways are verified for surface roughness using advanced profilometers.
Our commitment to quality ensures that the SPWL0000000211 consistently meets or exceeds OEM specifications. This dedication to excellence translates into reliable performance, reduced downtime, and lower total cost of ownership for fleet operators.
With a comprehensive warranty, this bearing offers peace of mind for even the most demanding applications.
