High Light Single Row Tapered Roller Bearing 70×150×35mmTapered Roller Bearing for Combined LoadSeparable Assembly Tapered Roller Bearing
1. Product Overview

30314D is single row separable tapered roller bearing of 303 series with strengthened D structure design. Its conical roller and raceway contact surface can simultaneously bear large radial load and unidirectional axial load. The separable cone assembly and cup simplify installation and preload adjustment, suitable for power transmission shafts under mixed radial-axial load conditions.

Formal quotation will be sent within 24 hours upon your inquiry.

2. Technical Specifiions

3. Core Advantages
  1. D enhanced roller structure improves contact area, boosting bearing capacity and impact resistance
  2. Tapered contact surface bears radial and one-way axial loads at the same time, widely used for power transmission
  3. Separable inner and outer components facilitate independent fitting and convenient preload adjustment
  4. Optimized roller finish reduces friction heat and running noise during continuous operation
  5. Standard metric size, fully interchangeable with same specifiion tapered roller bearings
  6. Customizable options: OEM laser marking, high-temperature grease, special clearance grades
  7. Reduce roller wear, prevent premature fatigue failure and extend service life of transmission assemblies.
4. Appliion Scenarios
  • Automotive drive axles, differential assemblies and vehicle gearboxes
  • Construction machinery, loader and excavator rotary transmission parts
  • Agricultural machinery gearboxes and power output shafts
