30328 Tapered Roller Bearing
30328 is a heavy‑duty single‑row tapered roller bearing from metric 303 high‑thrust series. Thanks to its steep tapered roller profile, this bearing achieves excellent unidirectional axial thrust capacity while retaining reliable radial load performance. The separable cone‑cup assembly allows convenient disassembly, inspection and precise preload adjustment during equipment assembly and field overhaul. Manufactured from premium GCr15 bearing steel, it maintains stable performance under continuous heavy‑load and impact‑prone operating scenarios, widely adopted by heavy‑equipment manufacturers and global spare‑part distributors.

Key Product Strengths
Enlarged taper angle provides superior one‑way axial thrust capability compared with conventional 302‑series tapered roller bearings
Fully detachable cone‑cup layout simplifies on‑site disassembly, visual inspection and preload fine‑tuning
Precision‑ground raceway and roller surfaces reduce frictional heat generation and slow wear progression
Multiple precision grades P0, P6, P5 are optional to satisfy different transmission accuracy requirements
Open‑type structure works compatibly with high‑viscosity grease lubrication and forced circulating oil lubrication systems
Heavy‑duty stamped steel cage keeps rollers stably positioned under fluctuating heavy‑load cycles
Real‑World Application Scenarios
30328 tapered roller bearings are extensively fitted on large heavy‑load rotating assemblies: mining plant main transmission housings, heavy‑duty off‑highway vehicle axle hubs, large‑capacity industrial gear reducers, oversized agricultural processing equipment, engineering machinery main gearboxes and heavy‑load conveyor drum groups. For working conditions with bidirectional axial thrust, this bearing is commonly installed in opposed paired configurations.
