33114 70x120x37mm Tapered Roller Bearing is suitable for industrial applications.

I. Basic Parameters and Structural Design

1. Dimensional Specifications (in line with relevant standards):
  • Bore diameter: 70mm
  • Outer diameter: 120mm
  • Total width: 37mm
  • Outer ring width: 29mm
  • Contact angle: 14.167° (medium contact angle design, suitable for both radial and unidirectional axial loads)
  • Minimum chamfer size: r1s.r2s ≥ 2mm; r3s.r4s ≥ 1.5mm
2.Separable Structure:
  • The inner ring assembly (including rollers and cage) and outer ring can be installed independently, facilitating preload adjustment and maintenance.
  • Cage material is usually steel or nylon; some models use brass to enhance wear resistance.
3.Material and Craftsmanship:
  • Main material: high-carbon chromium bearing steel (GCr15), with uniform surface hardness (HRC 58-62) and long wear life.
  • Some manufacturers adopt carburized steel or optimized heat treatment processes to further improve material strength and fatigue resistance.

II. Load and Speed Performance

1.Load-Carrying Capacity:
  • Basic dynamic load rating (C): 176-211kN
  • Basic static load rating (C0): 250-262kN
  • Capable of withstanding combined radial and unidirectional axial loads under typical working conditions.
2.Speed Characteristics:
  • Under oil lubrication:
    • Reference speed: 4,300r/min
    • Limiting speed: 5,300r/min
  • Under grease lubrication:
    • Recommended speed: ≤ 3,100r/min (to reduce frictional heat accumulation).

III. Application Fields

  • Industrial equipment: Robot joints, vibrating mills, packaging machinery, pulp and paper equipment, and other scenarios requiring axial positioning.
  • Transportation: Automobile gearboxes, truck wheel bearings, railway traction motors, adapting to high-speed and heavy-load conditions.
  • Engineering machinery: Slewing mechanisms of excavators, mining crushers, capable of withstanding impact loads and harsh environments.

IV. Design Advantages and Maintenance Key Points

  1. Performance Advantages:
    • Low friction characteristics: Optimized contact design between rollers and raceways, combined with low-viscosity lubricants, can reduce operating power consumption by 15%-20%.
    • Installation flexibility: Paired back-to-back or face-to-face mounting allows preload adjustment to enhance shafting rigidity.
  2. Maintenance Recommendations:
    • Clearance inspection: Axial runout should be controlled within 0.05-0.15mm; measure regularly with feeler gauges.
    • Lubrication cycle:
      • Normal working conditions: Replenish lithium-based grease every 3,000 hours.
      • High-temperature environments: Replenish every 1,000 hours, and use high-temperature resistant lubricants.
    • Installation specifications: Avoid direct hammering; hydraulic presses or heating to 80-100°C for hot mounting are recommended. Ensure the coaxiality error between the shaft and bearing housing is < 0.02mm.

V. Typical Technical Parameters Table

Item Value Range
Weight Approximately 1.7kg (typical reference)
Operating temperature range -30°C to +120°C (conventional conditions)
Axial clearance (after installation) 0.05-0.15mm
Vibration grade Conforming to V1-V3 standards (depending on precision level)

VI. Precautions

  • When using in pairs, select products from the same batch to ensure consistency in clearance and contact angle.
  • For long-term storage, keep sealed to prevent moisture, and use rust inhibitors to protect the surface from corrosion.
  • Avoid contact with acidic or alkaline substances to prevent material degradation.
The 33114 tapered roller bearing, with its standardized design and high reliability, is widely used in mechanical systems bearing combined loads.
