Product Description

Product Overview

Tapered Roller Bearings CR3914PX1 Replacement For PC220 Excavator Mining Machinery Supplier.
Our  Bearings are built for high-load, high-impact harsh environments. Ideal for excavators, loaders, cranes, and rollers, they feature advanced materials, precision manufacturing, and sealed designs to deliver superior durability, reduced maintenance, and extended life-maximizing equipment uptime and cost efficiency.

Appilcation

• Deep Groove Ball Bearings (Model: 6208, 6310): General-purpose, suitable for low-to-medium load scenarios.
• Tapered Roller Bearings (Model: 30207, 32212): Designed for combined radial and axial loads, ideal for high-impact conditions.
• Spherical Roller Bearings (Model: 22216, 23220): Accommodate slight misalignment between shafts and housings, used in heavy-duty equipment.
• Cylindrical Roller Bearings (Model: N315, NJ2214): High radial load capacity, suitable for high-speed rotating components.

Technical Specifications

• Material Control: Raw materials analyzed via spectrometry (composition deviation ≤0.5%), grain size ≥Grade 10 (GB/T 6394).
• Manufacturing Process: Processed by CNC grinders with full-flow machining, raceway roundness error ≤0.002mm, and laser marking for batch traceability.
• Testing Items:
  • Vibration testing (ISO 1940 G1 precision level)
  • Life test (passed 1000-hour continuous loading with failure probability <0.1%)
  • Sealing test (3bar air pressure, leakage <5ml/min)

 

Performance Indicator	Technical Highlights
High Load Capacity	Manufactured from fully through-hardened high-carbon chromium bearing steel (GCr15) with high-temperature tempering, increasing radial load capacity by 20% compared to standard bearings. Ideal for heavy-load parts like excavator booms and loader arms.
Impact & Wear Resistance	Raceways and rollers undergo superfinishing (Ra≤0.05μm) and special heat treatment (hardness HRC58-62), enhancing impact toughness by 30% to reduce wear in gravel and dusty environments.
High-Temperature & Dust Resistance	Built-in double-lip sealing (contact/non-contact options) with standard lithium-based grease (temperature range: -40ºC~+150ºC), enabling long-term operation in outdoor high-temperature and dusty conditions with a 50% extended maintenance cycle.
High-Precision Fit	Dimension accuracy meets ISO tolerance class IT3, and rotational precision reaches ISO P6 level, ensuring stability during high-speed operation and reducing equipment vibration and noise.
