32248 Tapered Roller Bearing
32248 is an extra‑large single‑row tapered roller bearing belonging to metric 322 series. It adopts a moderate taper angle, delivering reliable comprehensive performance for heavy radial load and moderate unidirectional axial thrust. The separable cone‑cup assembly enables convenient disassembly, preload adjustment and component replacement during equipment assembly and field overhaul. Manufactured from premium GCr15 bearing steel, it performs steadily under severe heavy‑load and impact‑prone working environments, widely favoured by large‑equipment OEM factories and global spare‑part distributors.

Key Product Strengths
Moderate taper‑angle design achieves good balance between radial‑load capacity and single‑direction axial thrust for heavy mixed‑load application scenarios
Fully detachable cone‑cup layout simplifies on‑site disassembly, visual inspection and accurate preload fine‑tuning
Precision‑ground roller and raceway surfaces reduce frictional heat accumulation and slow down component wear progression
Multiple precision grades P0, P6, P5 optional to satisfy different transmission‑accuracy requirements
Open‑type bearing structure compatible with high‑viscosity grease lubrication and forced circulating oil lubrication systems
Heavy‑duty stamped steel cage maintains stable roller arrangement under large fluctuating heavy‑load cycles
Real‑World Application Scenarios
32248 tapered roller bearings are widely deployed on extra‑large heavy‑duty rotary assemblies: large‑capacity industrial gear reducers, mining plant main transmission housings, oversized off‑highway machinery axle hubs, heavy agricultural processing equipment, engineering machinery main gearboxes and heavy‑load conveyor main shafts. For working conditions with bidirectional axial thrust, this bearing is commonly installed in opposed paired configurations.
