30238 Tapered Roller Bearing
30238 is a large‑bore single‑row tapered roller bearing from the proven 302 metric series. Its non‑locating separable cone and cup assembly lets technicians separate inner and outer components freely during assembly and overhaul work. This unit is purpose‑built for rotating shafts subjected to combined radial load plus unidirectional axial thrust. Forged from premium GCr15 bearing steel, it holds stable performance under sustained heavy loads and cyclic impact conditions, widely sourced by large equipment workshops and international wholesale spare‑part suppliers.

Key Product Strengths
Detachable inner cone and outer cup, simplifies part swapping, field inspection and preload fine‑tuning
Optimized roller‑raceway contact geometry minimises heat build‑up during continuous heavy‑duty rotation
Multiple accuracy variants P0, P6, P5 can be selected to satisfy diverse transmission precision requirements
Open‑type construction works well with high‑temperature grease or forced circulating oil lubrication setups
Heavy‑gauge stamped steel cage maintains stable roller positioning under variable shock‑loaded cycles
Real‑World Application Scenarios
30238 tapered roller bearings find wide application on oversized heavy rotating assemblies: large mining transmission housings, heavy‑duty industrial gearboxes, off‑highway heavy vehicle axle hubs, oversized farm processing machinery, engineering plant main reducer units and heavy‑load conveyor drum assemblies. To counteract bidirectional axial thrust, this bearing is commonly installed in mirrored opposing pairs.
