30314D is a high-load single-row metric tapered roller bearing complying with ISO & JIS industrial standards, overall dimension 70×150×38 mm, widely adopted in automotive and heavy machinery transmission systems.
It is manufactured from high-purity hardened GCr15 bearing steel, equipped with pressed steel stamping cage to guide tapered rollers evenly. The D upgraded internal geometry greatly improves dynamic load capacity and fatigue life under alternating shock loads. Open unsealed design matches closed axle housings and gearbox oil bath lubriion environment perfectly. Single-row tapered structure bears simultaneous heavy radial load and unidirectional axial thrust, always used in back-to-back paired arrangement to realize bidirectional axial positioning for vehicle axles and transmission shafts.

*Check matched bearing models to complete your mechanical assembly.
A: Inner bore 70 mm, outer diameter 150 mm, total width 38 mm.
A: Optimized enhanced internal structure, increased load capacity standard for NTN/KOYO series tapered roller bearings.
A: Open Type, no rubber/metal seals on both sides, open structure.
A: Single unit only withstands one-way axial force; two bearings mounted oppositely can bear bidirectional axial loads.
A: Grease lubriion: 2300 rpm; Oil lubriion: 3000 rpm.
A: Not recommended; open design relies on closed housing to block dust and moisture.
