Product Detail

Product Description: Tapered Roller Bearing 16JSS300T-1707109 for Fast 16-Speed Truck Transmission

The Tapered Roller Bearing 16JSS300T-1707109 (also supplied as 16JS300T-1707109, 16JS200T-1707109, and JS220-1707109) is a genuine OEM replacement bearing component specifically designed for the 16JSS300T and related series 16-speed manual transmissions manufactured by FAST (Fast Gear/Fast Transmission), widely used in Sinotruk (HOWO), Shacman (F3000, Delong), and FAW Jiefang heavy-duty trucks. As a subbox combined bearing, this precision-ground bearing serves as a critical structural and motion component within the auxiliary gearbox section of multi-gear heavy-duty transmissions, withstanding the high axial and radial loads generated during gear selection, torque transfer, and power distribution.
