Welcome to Linqing Xinshengdi Bearing Co., Ltd.
B17-116 High-Speed Automotive Alternator Bearing
- Extreme RPM Endurance: Polished raceways and precisely matched balls allow for the ultra-high rotational speeds required by heavy-duty alternators.
- Radial Tension Resistance: Thickened outer ring and optimized contact geometry to counteract the heavy, continuous side-load of tight serpentine belts.
- High-Temp Polyurea Lubrication: Pre-packed with an advanced shear-stable grease that will not leak or evaporate under extreme operating heat.
Deep Application & Technical Narrative:The B17-116 is a premier deep groove ball bearing instantly recognized by automotive electrical rebuilders worldwide. It is designed specifically for the front drive-end of high-output alternators used in modern SUVs, commercial trucks, and vehicles with heavy electrical loads. The drive-end of an alternator is subjected to intense, continuous radial tension from the engine's drive belt, alongside brutal thermal cycling from the engine block.
If the bearing's internal grease liquefies and escapes, the alternator will seize in a matter of days. At DBS Bearings, we eliminate this risk through our meticulous assembly process. Inside our dedicated workshop, we utilize precise volumetric grease injection machines, and every B17-116 unit undergoes a 100% individual manual inspection to verify seal integrity. We provide auto-electrical B2B distributors with a heavy-duty component that guarantees uninterrupted power generation in the harshest under-hood environments.
Customized B2B Supply & Packaging Solutions:We cater directly to automotive electrical remanufacturing networks. The B17-116 can be supplied in high-density bulk industrial tubes for rapid assembly line access, minimizing packaging waste for large-scale rebuilders.
Targeted Technical Clarifications (FAQ):
Q: Is the B17-116 interchangeable with standard industrial bearings?A: Absolutely not. While dimensions may seem similar to standard bearings, the B17-116 features specialized internal clearances and high-temperature grease critical for alternator survival.
Q: What type of seals are used on this bearing?A: We utilize advanced, non-contact or light-contact rubber seals (depending on specification) to provide a perfect balance between blocking debris and minimizing rotational drag.
