30326 Tapered Roller Bearing
30326 is a large‑size single‑row tapered roller bearing from the 303 high‑thrust metric series. Thanks to its enlarged taper angle, this bearing prioritizes strong unidirectional axial thrust while keeping excellent radial load‑bearing capability. The separable cone‑cup assembly allows technicians to separate inner and outer components freely, making preload adjustment and spare‑part replacement easy during assembly and field maintenance. Produced from premium GCr15 bearing steel, it delivers consistent performance under long‑term heavy‑load operation and irregular impact shocks, widely trusted by heavy‑equipment manufacturers and global spare‑part wholesalers.

Key Product Strengths
Larger taper angle delivers outstanding one‑way axial thrust capacity, surpassing ordinary 302‑series tapered roller bearings
Fully detachable cone‑cup layout simplifies on‑site disassembly, visual inspection and precise preload fine‑tuning
Precision‑ground raceway and roller surfaces lower frictional heat build‑up and effectively extend service life
Multiple precision grades P0, P6, P5 optional for different transmission accuracy requirements
Open‑type design works well with high‑viscosity grease lubrication and forced circulating oil lubrication
Reinforced stamped steel cage keeps rollers well‑positioned under heavy fluctuating load cycles
Real‑World Application Scenarios
30326 tapered roller bearings are widely applied on large heavy‑duty rotating assemblies: mining plant main transmission units, heavy‑duty off‑highway vehicle axle hubs, large‑capacity industrial gear reducers, heavy agricultural processing machines, engineering machinery gearboxes and heavy‑load conveyor drum groups. When bidirectional axial thrust exists, it is commonly installed in back‑to‑back paired configurations.
