30315 Tapered Roller Bearing

Model 30315 is a popular single‑row tapered roller bearing of 303 metric series. Different from 302 series, it comes with a steeper taper angle to deliver stronger axial thrust capacity. The inner cone and outer cup can be completely separated, bringing great convenience for mounting, removal and preload adjustment. Produced from premium GCr15 bearing steel, this unit performs reliably under mixed radial and heavy one‑way axial loads, which makes it a favourite replacement component for vehicle repair centres and industrial equipment OEM projects.

Core dimension: 75 × 160 × 37 mm (d × D × T)

Key Product Strengths

• Steeper taper angle design provides outstanding one‑direction axial load capability compared with ordinary 302 series bearings

• Fully separable cone‑cup construction, easy for field disassembly, inspection and preload setting

• Carefully ground raceway surface lowers friction heat and improves overall service lifespan

• Multiple precision classes P0, P6, P5 available to satisfy various transmission accuracy requirements

• Open‑type structure compatible with high‑viscosity grease and circulating oil lubrication solutions

Real‑World Application Scenarios

30315 tapered roller bearings are widely used on assemblies requiring strong thrust load capacity: medium‑heavy truck axle hubs, high‑torque industrial gearboxes, construction machinery reducers, mining auxiliary equipment, heavy agricultural machinery transmission parts and heavy‑duty conveyor rotating shafts. To handle bidirectional axial force, this bearing is mostly assembled in opposing pairs.
