30228 Tapered Roller Bearing
The 30228 is a standard 302‑series single‑row tapered roller bearing for metric‑sized equipment. Thanks to its separable cone and outer cup structure, installers can freely adjust bearing preload during assembly and maintenance. This bearing is engineered to cope with combined radial loads plus one‑sided axial thrust. Made of high‑quality GCr15 bearing steel, it maintains stable running performance under continuous heavy‑load and intermittent shock conditions, widely sourced by machinery repair dealers and overseas equipment manufacturers.

Key Product Strengths
Detachable cone‑cup structure facilitates on‑site inspection, component replacement and preload fine‑tuning
Carefully optimized raceway profile minimizes friction loss and operating temperature rise
Available in P0, P6, P5 precision grades to match general‑use and high‑precision transmission demands
Open‑type design works well with grease lubrication as well as forced circulating oil lubrication
Durable steel cage holds rollers in stable position under variable heavy‑load cycles
Real‑World Application Scenarios
30228 tapered roller bearings are widely deployed on heavy rotating assemblies: off‑highway vehicle axle hubs, heavy industrial gear reducers, mining processing plant machinery, large‑scale farm equipment, construction machine transmission parts and heavy‑duty conveyor drum stations. For bidirectional thrust requirements, this model is frequently mounted in opposing paired configurations.
