Product Description
Low Friction Tapered Roller Bearing 70x120x37mm 33114 Bearing
33114 70x120x37mm Tapered Roller Bearing is suitable for industrial applications requiring reliable performance under combined radial and axial loads.
Basic Parameters and Structural Design
  • Dimensional Specifications: 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)
  • Chamfer Size: r1s.r2s ≥ 2mm; r3s.r4s ≥ 1.5mm
  • Separable Structure: Inner ring assembly and outer ring can be installed independently, facilitating preload adjustment and maintenance
  • Cage Material: Steel or nylon; some models use brass for enhanced wear resistance
  • Main Material: High-carbon chromium bearing steel (GCr15) with uniform surface hardness (HRC 58-62)
Load and Speed Performance
  • Basic Dynamic Load Rating (C): 176-211kN
  • Basic Static Load Rating (C0): 250-262kN
  • Oil Lubrication: Reference speed: 4,300r/min, Limiting speed: 5,300r/min
  • Grease Lubrication: Recommended speed: ≤ 3,100r/min
Application Fields
  • Industrial Equipment: Robot joints, vibrating mills, packaging machinery, pulp and paper equipment
  • Transportation: Automobile gearboxes, truck wheel bearings, railway traction motors
  • Engineering Machinery: Slewing mechanisms of excavators, mining crushers
Design Advantages and Maintenance
Performance Advantages:
  • Low Friction Characteristics: Optimized contact design can reduce operating power consumption by 15%-20%
  • Installation Flexibility: Paired back-to-back or face-to-face mounting allows preload adjustment
Maintenance Recommendations:
  • Clearance Inspection: Axial runout should be controlled within 0.05-0.15mm
  • Lubrication Cycle: Normal conditions: replenish lithium-based grease every 3,000 hours; High-temperature: every 1,000 hours
  • Installation Specifications: Avoid direct hammering; use hydraulic presses or heating to 80-100°C
Technical Parameters
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)
Precautions
  • When using in pairs, select products from the same batch to ensure consistency
  • For long-term storage, keep sealed to prevent moisture and use rust inhibitors
  • 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.
