In the demanding world of heavy machinery and trucking, components that manage immense axial (thrust) forces are critical for reliability and performance. As a premier example of precision-engineered SANY parts, the OEM 131402010238A003 Tapered Roller Thrust Bearing is designed specifically for this challenging role. This genuine bearing, identified by the exact reference number 131402010238A003, provides superior load-carrying capacity and durability in applications where heavy axial loads are combined with moderate radial forces. Its tapered roller design ensures optimal load distribution, minimizing friction and wear while maintaining precise shaft positioning. Choosing the authentic 131402010238A003 component is essential for ensuring the longevity and smooth operation of critical assemblies in SANY equipment, preventing costly downtime and premature failure.

The SANY 131402010238A003 is a specialized tapered roller thrust bearing, engineered to accommodate heavy axial loads in one direction while also handling moderate radial loads. Unlike simple ball thrust bearings, its tapered rollers are positioned at an angle between the bearing’s two washers (races). This design causes the rollers to raceways contact along a line, distributing loads over a larger surface area. This results in a significantly higher load rating and greater rigidity compared to other thrust bearing types. The geometry of the 131402010238A003 also induces a small radial force component, which must be considered in the housing design.
This bearing is typically used in pairs to handle thrust in both directions or combined with radial bearings. Its primary role in SANY machinery is in applications like heavy-duty gearboxes, vertical pumps, crane slewing rings, and the swing mechanisms of excavators, where substantial axial forces are generated during operation. The precision manufacturing of the 131402010238A003 ensures smooth roller movement, minimal friction, and consistent performance under the extreme stresses found in construction and mining equipment. Its robust construction directly contributes to the machine’s operational stability and service life.
The conical rollers and matching raceways are precision-ground to ensure true rolling motion and optimal line contact. This design efficiently manages combined loads (axial and radial) and prevents edge loading, which is a common failure point in simpler bearings.
Manufactured from vacuum-degassed, case-hardened bearing steel (e.g., SAE 52100), the 131402010238A003 components offer exceptional hardness, wear resistance, and fatigue life, capable of withstanding shock loads and continuous operation.
The rollers are guided and evenly spaced by a robust cage, typically made from machined brass or stamped/pressed steel. This cage in the 131402010238A003 prevents roller skewing and clustering, ensuring smooth operation and efficient lubrication flow.
All components undergo advanced heat treatment processes, including carburizing and tempering. This stabilizes the microstructure of the steel, providing a hard, wear-resistant surface and a tough, shock-absorbing core for the 131402010238A003 bearing.
Manufactured to ISO and SANY’s stringent tolerance classes (e.g., P6 or higher), the 131402010238A003 ensures exact inner and outer ring widths, bore diameters, and raceway angles. This guarantees predictable performance and precise axial positioning.
The bearing geometry and cage design facilitate effective grease retention or oil flow. Proper lubrication of the 131402010238A003 is critical for dissipating heat, preventing metal-to-metal contact, and extending service life in harsh environments.

The 131402010238A003 bearing is deployed in key areas of SANY equipment where robust axial load support is non-negotiable. Its design makes it ideal for several demanding applications.
Cleanliness: The bearing (part 131402010238A003) and housing must be immaculately clean. Any debris will cause indentation and premature failure.
Fitting: The shaft washer (inner ring) is typically an interference fit on the shaft. The housing washer (outer ring) usually has a transitional or slight clearance fit. Use proper tools for pressing; never strike the bearing directly.
Axial Clearance/Preload: This is critical. Tapered roller thrust bearings often require a specific axial clearance or preload, set by selective shims, spacers, or adjustable nuts. Incorrect setting leads to overheating (if too tight) or excessive play and impact damage (if too loose). Always follow the SANY service manual specification for the 131402010238A003 application.
Alignment: The supporting surfaces for the bearing washers must be square to the shaft axis. Misalignment causes uneven load distribution and rapid wear.
Lubricant Selection: Use only high-quality grease or oil recommended by SANY for the operating temperature and speed range. The lubricant must have excellent pressure resistance (EP additives) and anti-wear properties.
Greasing: For grease-lubricated applications, fill the housing cavity 1/3 to 1/2 full. Over-greasing can cause churning and overheating. Follow regreasing intervals based on operating hours and conditions.
Condition Monitoring: Regularly monitor for signs of bearing distress: unusual noise (growling, clicking), increased operating temperature, or vibration. Any of these can indicate misalignment, contamination, or wear in the 131402010238A003 bearing.
Contamination Prevention: Maintain effective seals. Dirt, dust, and water ingress are the leading causes of bearing failure. Inspect seals during every service interval and replace if damaged.
This bearing is a precision load-bearing component. Substitutes can compromise entire machine systems.
Only the genuine 131402010238A003 carries the verified dynamic (C) and static (C0) load ratings tested and validated by SANY for your specific equipment model.
SANY provides traceability for the bearing steel and heat treatment processes, ensuring the 131402010238A003 meets the required hardness, toughness, and fatigue life specifications.
Non-OEM bearings may have subtle dimensional variances that affect axial clearance, preload, and alignment, leading to improper function and early failure. The 131402010238A003 fits perfectly.
Using the specified 131402010238A003 bearing maintains your equipment warranty and ensures the designed system integrity, protecting adjacent gears, shafts, and housings from damage.
