Welcome to Linqing Xinshengdi Bearing Co., Ltd.
H913840/H913810 Heavy Tapered Roller Bearing
- "Heavy" Series Architecture: Oversized rollers and thickened rings provide vastly superior static load capacities for extreme shock environments.
- Optimized Crowned Rollers: The rolling elements feature a microscopic crown profile, preventing edge-loading and stress concentration under heavy shaft deflection.
- Boutique Manual Validation: Every heavy-duty set is physically handled and inspected in our Yandian workshop to guarantee perfect raceway matching.
- Exceptional Wear Resistance: Advanced thermal hardening ensures the raceways resist subsurface spalling under relentless, high-tonnage pressure.

Product Introduction
The H913840/H913810 represents the heavy-hitting tier of tapered roller bearings. The "H" prefix in the part number explicitly designates this as a "Heavy" series bearing, engineered with thicker raceways and larger rollers than standard series bearings of similar dimensions. Measuring 69.85x146.05x41.275mm, it is designed to endure punishing shock loads in heavy differential pinions, massive construction equipment, and deep-hole drilling machinery. Because these environments do not tolerate failure, we rely strictly on meticulous human expertise for quality assurance. Inside our residential-scale facility, our specialized team manually pairs the heavy cone and cup, verifying the fluid rotation and dimensional uniformity of every H913840/H913810. This intense, anti-automation quality control process allows us to catch the minute imperfections that factory robots miss, ensuring unparalleled structural integrity.
Applications
Pinion shafts in heavy commercial truck differentials.
Drive hubs on heavy earth-moving equipment (excavators, loaders).
Heavy industrial gearboxes and mining conveyors.

FAQ
Q: What is the difference between an "LM" series and an "H" series bearing?
A: "LM" stands for Light Medium, while "H" stands for Heavy. Even if they have somewhat similar bore sizes, the "H" series will have significantly larger rollers, a thicker cup, and a much higher load rating.
Q: Can this bearing handle high speeds?
A: Heavy series tapered bearings are generally designed for immense torque and load at low to moderate speeds, rather than high-RPM applications.
OEM & Custom Service
For specialized B2B industrial clients, we can supply the H913840/H913810 with matched spacer rings for pre-set bearing assemblies, drastically reducing installation time for heavy gearbox manufacturers.
Packing & Delivery
We utilize reinforced, moisture-blocking packaging to protect this high-mass steel during long ocean transits. Master cartons are consolidated onto solid wooden pallets, delivering perfect stock to your heavy machinery partners globally.
