The Shacman X5000 Deep Groove Ball Bearing with OEM number 1003500131 is a precision rolling-element bearing designed for high radial and moderate axial loads in critical drivetrain and auxiliary systems. This genuine bearing ensures low friction, high rotational accuracy, and extended service life in harsh heavy-duty environments. The 1003500131 deep groove ball bearing is manufactured from premium chrome steel (SAE 52100), heat-treated to achieve uniform hardness of 60–65 HRC, and precision ground to P6 or ABEC-3 tolerance class.
Engineered specifically for Shacman X5000 trucks, this bearing is used in gearboxes, alternators, water pumps, fan hubs, and belt tensioners. OEM 1003500131 features a deep raceway geometry that allows high load capacity while maintaining quiet operation. The bearing comes pre-lubricated with high-temperature lithium-based grease, sealed on both sides with contact rubber seals (2RS) to prevent contamination ingress and retain lubricant.
Aftermarket bearings often use lower-grade steel or poor heat treatment, leading to premature fatigue, spalling, or seizure. The genuine 1003500131 deep groove ball bearing is 100% inspected for radial play, noise (Anderon meter), and dimensional accuracy. Its optimized internal clearance (C3) allows for thermal expansion and shaft deflections common in heavy-duty truck applications.
Choosing OEM 1003500131 guarantees correct fitment, reliable lubrication, and long-term durability. This bearing reduces downtime and maintenance costs in Shacman X5000 fleets, ensuring that auxiliary components operate at peak efficiency.
Deep groove ball bearings are the most common yet critical components in rotating machinery. A failing bearing causes noise, vibration, increased friction, and eventual component seizure. OEM 1003500131 is manufactured with premium bearing steel that undergoes vacuum degassing to minimize oxide inclusions, ensuring maximum fatigue life. The raceway curvature is optimized to reduce edge stress under misalignment, a common condition in heavy trucks.
Aftermarket bearings often use standard clearance (CN) which may be too tight for high-temperature applications, leading to preload and premature failure. Genuine 1003500131 features C3 clearance, allowing for thermal expansion of shafts up to 120°C. The rubber seals (2RS) are made of nitrile rubber with a steel insert, providing excellent dirt and moisture resistance without increasing torque significantly.
Before installation, inspect the housing and shaft for burrs or damage. Clean thoroughly with a lint-free cloth. Apply a thin film of bearing grease to the shaft and housing bore. Use a bearing heater (induction heater) or an oven to warm the bearing to 80–100°C for easier mounting – never use an open flame. Press the bearing onto the shaft or into the housing using a sleeve that contacts only the ring being fitted (inner ring for shaft, outer ring for housing).
Avoid hammering directly on the bearing. After installation, verify that the bearing rotates smoothly without binding. For Shacman X5000 alternator or fan hub applications, torque the retaining nut to factory specification. Always replace the bearing if the seal is damaged or if the bearing feels rough when rotated by hand.
Each 1003500131 deep groove ball bearing is produced from continuous-cast bearing steel. The rings are rough-turned, then heat-treated in a controlled atmosphere furnace. After grinding, the raceways are superfinished to a surface roughness of Ra 0.05 µm. The balls are grade 10 (sphericity within 0.1 µm). Assembled bearings are washed, lubricated with the specified grease, and sealed.
100% of bearings are tested for radial runout (bore to outer ring) on a Anderon meter for noise. Every bearing is measured for radial clearance (C3 range) and torque. Random samples are subjected to a 200-hour accelerated life test under 30% of dynamic load rating. The genuine 1003500131 consistently achieves L10 life exceeding 500,000 km in Shacman fleet applications.
OEM 1003500131 replaces Shacman part numbers 1003500130, 612600010234, and DZ13241813025. It is fully compatible with Shacman X5000 trucks, as well as X3000 and X6000 series that use the same alternator, water pump, or fan hub assemblies. This bearing cross-references to industry standard 6207-2RS (35x72x17 mm with C3 clearance).
When replacing bearings in auxiliary drives, always check the shaft and housing for wear. If the shaft is scored, replace the component or use a Speedi-Sleeve. Use only genuine Shacman bearings to maintain the original interference fit. For water pump applications, ensure the bearing is properly centered to avoid seal leakage.
Fleet operators report that using genuine 1003500131 bearings extends alternator life by 300,000 km and water pump life by 200,000 km compared to generic bearings. The combination of correct clearance, high-quality steel, and effective sealing dramatically reduces roadside failures.
Shacman’s validation includes a 500-hour grease life test at 8,000 RPM and 100°C ambient temperature. The bearing shows no grease leakage and less than 15 dB increase in noise floor. A mud and water ingress test (IP6X dust, water spray) confirms that the 2RS seals prevent contamination – after 100 hours, no foreign material entered the bearing cavity.
In field trials across 150 trucks in construction and mining, the 1003500131 bearing achieved an average service life of 750,000 km on fan hubs and 600,000 km on alternators. This is more than triple the life of non-genuine bearings. By choosing OEM 1003500131, you minimize unplanned maintenance and maximize vehicle uptime.
