32221 Tapered Roller Bearing
32221 is a widely‑used single‑row tapered roller bearing belonging to the 322 metric series. It adopts a moderate taper angle, achieving a good balance between radial load capacity and unidirectional axial thrust performance. This separable‑type bearing includes independent inner cone assembly and outer cup, making preload adjustment, installation and field maintenance much easier. Manufactured from premium GCr15 bearing steel, it delivers stable performance under medium‑heavy mixed‑load operating conditions. It is a preferred spare‑part for vehicle repair centres and general industrial equipment manufacturers worldwide.

Key Product Strengths
Moderate taper‑angle design balances radial carrying capacity and one‑way axial thrust, suitable for comprehensive load‑bearing scenarios
Fully separable cone‑cup construction facilitates quick disassembly, visual inspection and accurate preload fine‑tuning
Precision‑ground roller and raceway surfaces reduce friction heat and effectively extend service cycles
Multiple precision grades P0, P6, P5 are optional to satisfy different transmission‑accuracy requirements
Open‑type structure compatible with high‑viscosity grease lubrication and circulating oil lubrication systems
Durable stamped steel cage keeps rollers stably arranged under fluctuating medium‑heavy load cycles
Real‑World Application Scenarios
32221 tapered roller bearings are widely applied on medium‑heavy rotating assemblies: truck and heavy‑vehicle axle hubs, general‑purpose industrial gear reducers, construction machinery transmission parts, heavy agricultural machinery and medium‑load conveyor shaft groups. For working conditions with bidirectional axial thrust, this bearing is normally installed in opposed paired layouts.
