Product Description
Precision Tapered Roller Bearing 31313 Split Design For Engineering Machinery
31313 Tapered Roller Bearing features optimized raceways and rollers that significantly boost fatigue life. This high-performance mechanical component is designed to bear combined radial and unidirectional axial loads.
Basic Parameters
  • Dimensions: Inner diameter 65mm, outer diameter 140mm, total width 36mm, inner ring width 33mm, outer ring width 23mm, weight approximately 2.37kg
  • Speed: Limiting speed 4800r/min (SKF data), reference speed 3600r/min
  • Precision Class: Default P0 (general grade), with higher precision (P6) available for custom requirements
Structural Features
  • Split Design: Separable inner ring, outer ring, and roller assembly for easy installation and maintenance
  • Optimized Design: Logarithmic curve crown design disperses edge stress, increasing fatigue life by over 12%
  • Load Capacity: Basic dynamic load rating 185.8kN, basic static load rating 218.6kN
  • Contact Angle: 28°48'39" for combined radial and axial load bearing (requires paired usage)
Materials and Manufacturing
  • Material: High-carbon chromium bearing steel (GCr15) with quenching and tempering treatment
  • Hardness: HRC58-62 for high strength and wear resistance
  • Standards: Compliant with GB/T 297-94 and DIN ISO 355 standards
Application Fields
  • Engineering Machinery: Crushers, mining machinery transmission systems
  • Automotive Industry: Heavy-duty truck drive axle main reducers
  • Industrial Equipment: Submersible electric pumps, marine pumps, disc mills
Installation and Maintenance
  • Installation Methods: Pressure method, temperature difference method (heating ≤100℃), hydraulic method
  • Clearance Adjustment: Axial clearance 0.05-0.12mm (CN group standard)
  • Lubrication: Lithium-based grease (NLGI Grade 2) or ISO VG 46 lubricating oil
  • Temperature Range: -30℃ to +120℃ operating range
Performance Advantages
  • High Load Capacity: 12.13% increased dynamic load compared to traditional models
  • Extended Service Life: Over 20% longer life compared to linear designs
  • Enhanced Reliability: Stable operation in harsh environments with easy wear inspection
