Understanding the 6206 2RS C3 Bearing and Its Industrial Role

The 6206 2RS C3 deep groove ball bearing is engineered for high-load scenarios where operational reliability is non-negotiable. With an inner diameter of 30mm, outer diameter of 62mm, and width of 16mm, this bearing accommodates radial and axial loads up to 19.8kN and 14.3kN respectively. The "C3" clearance designation ensures optimal performance in thermally unstable environments, making it ideal for industrial motors, conveyor systems, and agricultural machinery. Its dual rubber seals (2RS) provide superior contamination resistance, extending service life by 40% compared to open-type bearings.

Technical Breakdown: Dimensions and Load Ratings

Critical measurements for the 6206 2RS bearing dimensions align with ISO 15:1998 standards. Key parameters include:

  • Dynamic Load Capacity: 19.8 kN (radial), 14.3 kN (axial)
  • Maximum RPM: 9,500 (oil lubrication), 6,800 (grease)
  • Operating Temperature: -30°C to +120°C

Third-party testing under ISO 281:2007 conditions demonstrates 90% survival probability after 15,000 hours at 2,400 RPM.

Engineering Superiority in Design

Compared to basic 6206 bearings, the C3 variant delivers 18% higher shock absorption due to increased internal clearance. The 2RS seals reduce lubricant leakage by 72% in high-vibration environments, validated by ASTM D4172 wear tests. Manufacturers like SKF and NTN utilize nitrogen-enriched steel alloys to achieve Rockwell C62 hardness, doubling fatigue resistance versus standard bearings.

Manufacturer Performance Analysis

Brand Dynamic Load (kN) Noise Level (dB) Price/Unit ($)
SKF 6206-2RS/C3 20.1 42 28.50
NSK 6206DUC3 19.5 45 24.90
FAG 6206.2RSR.C3 19.2 47 22.75

Tailored Solutions for Extreme Conditions

Specialized versions include:

  • High-Temperature: Viton seals (up to 200°C) with molybdenum-disulfide grease
  • Corrosive Environments: 316 stainless steel construction with 92% salt spray resistance
  • Precision Grade: ABEC-5 tolerance (0.0025mm runout) for CNC spindles

Application-Specific Success Stories

A cement plant reduced downtime by 63% after replacing standard 6206 bearings with C3 variants in rotary kiln fans. Automotive testing showed 31% lower heat generation in EV traction motors using custom-lubricated 6206 2RS units. Agricultural combine harvesters achieved 12,000 operating hours without relubrication in dusty conditions.

Why 6206 2RS C3 Bearings Dominate Industrial Applications

The 6206 2RS C3 deep groove ball bearing combines unmatched load distribution (85% stress reduction vs. single-row designs) with contamination protection exceeding IP6X standards. Field data from 87 manufacturing facilities confirms 22% longer mean time between failures (MTBF) compared to C0 clearance bearings. For operations requiring precision under variable thermal conditions, this bearing remains the engineering consensus choice.

FAQS on 6206 2rs c3 bearing

Q: What are the dimensions of a 6206 2RS C3 bearing?

A: The 6206 2RS C3 bearing has an inner diameter of 30 mm, outer diameter of 62 mm, and width of 16 mm. The "C3" indicates a larger internal clearance for high-temperature or high-speed applications.

Q: How does the 6206 2RS bearing differ from standard 6206 bearings?

A: The 6206 2RS bearing features two rubber seals (2RS) for improved dust and moisture protection compared to open or shielded variants. It retains the same 30x62x16 mm dimensions as the standard 6206 series.

Q: What applications suit a 6206 2RS deep groove ball bearing?

A: This bearing is ideal for electric motors, pumps, and industrial machinery requiring moderate loads, sealed protection, and reliable performance. Its deep groove design supports radial and axial loads.

Q: What does "C3" mean in a 6206 2RS C3 bearing?

A: "C3" denotes a greater internal clearance than standard bearings, accommodating thermal expansion in high-speed or high-temperature environments. It balances reduced friction with thermal stability.

Q: Can a 6206 2RS bearing replace a 6205 2RS bearing?

A: No, the 6206 has a larger 62 mm outer diameter vs. the 6205's 52 mm. Always verify dimensional compatibility (30x62x16 mm for 6206) before substitution.
