Tapered Roller Bearing Reinforced DU Structure

,

Heavy Load Transmission Shaft Bearing

Produktbeschreibung
1. Product Overview

30317DU is single row separable tapered roller bearing adopting upgraded DU reinforced roller structure. Tapered contact surfaces between rollers and raceways can bear heavy radial load and unidirectional axial load simultaneously. Separable inner cone and outer cup facilitate installation, disassembly and preload adjustment. It is widely applied to heavy-duty transmission systems subjected to impact load and mixed working loads.

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

2. Technical Specifications

Model: 30317DU

Dimensions: d85 mm, D180 mm, T42 mm

Net weight: approx 4.85 kg

Dynamic load rating Cr: 295 kN

Static load rating Cor: 372 kN

Limiting speed: Grease 2700 rpm, Oil 3500 rpm

Structure: Single row tapered rollers, DU strengthened design, separable inner cone & outer cup

Material: GCr15 bearing chrome steel, stamped steel cage

Clearance: Standard factory preset clearance, custom clearance available

Complete dimension drawings and load data available on request.

3. Core Advantages
  1. DU optimized roller structure expands contact area, greatly improves load capacity and shock resistance
  2. Tapered raceway structure withstands radial force and one-way axial thrust at the same time
  3. Separable inner and outer components support independent fitting and flexible preload adjustment
  4. Superfinished roller surface reduces friction heat and running noise during continuous operation
  5. Standard metric dimensions, fully interchangeable with same specification tapered roller bearings
  6. Customizable options: OEM laser marking, high temperature resistant grease, special clearance grades

Effectively reduce roller fatigue wear and extend service life of heavy machinery transmission assemblies.

4. Application Scenarios
  • Truck, bus drive axles, differential and vehicle gearbox assemblies
  • Excavators, loaders and other construction machinery rotary transmission components
  • Agricultural machinery gearboxes and power output drive shafts
  • Heavy industrial reducers and large conveyor roller supporting structures
  • Mining machinery and engineering vehicle wheel hub assemblies
  • General mechanical equipment operating under heavy combined radial and axial loads
