The FONKIN NC206 is a high-performance insert-type spherical ball bearing unit, specifically engineered for drive systems requiring self-alignment and effortless installation. As a core component of the NC series, it seamlessly integrates a spherical outer ring with a NU-LOC concentric fixing collar, delivering exceptional reliability and adaptability to general industrial environments. Its embedded design sets it apart from standard bearing components, ensuring stable performance and ease of assembly in a wide range of applications.
1. Detailed Dimensional Parameters
Compliant with international bearing standards (ISO 355 & DIN 628), the NC206 features an inner diameter (d) of 30mm and an outer diameter (D) of 62mm. The minimum chamfer size (r) is 1.0mm, with a tolerance grade of P0 (ISO 492). Its basic dynamic load rating (C) is 19.5kN, and the basic static load rating (C₀) is 11.3kN, providing robust load-bearing capacity for medium-duty operations. The unit is designed for use with cast iron bearing housings, typically in two-bolt or four-bolt mounting configurations for secure fixation.
2. Structural & Material Specifications
- Bearing Components: The inner ring, outer ring, and rolling elements are constructed from high-carbon chromium bearing steel (AISI 52100/SUJ2), refined via vacuum degassing to minimize impurities. After precision heat treatment, they achieve a hardness of 60-64 HRC, offering excellent wear resistance, fatigue strength, and dimensional stability under cyclic loading.
- NU-LOC Fixing Collar: Manufactured from high-toughness carbon steel (S45C), this concentric locking mechanism enables quick, shaft-friendly installation without the need for additional keyways or set screws, preventing shaft damage and ensuring precise alignment.
- Sealing System: Equipped with contact-type seals (usually NBR rubber), providing effective protection against dust, moisture, and contaminants, making it suitable for harsh operating conditions.
- Bearing Housing: Matched with cast iron (HT200) housings for high rigidity, impact resistance, and long-term durability.
3. Core Features & Performance Advantages
- Superior Self-Alignement: The spherical outer ring design allows automatic alignment with the bearing housing, compensating for shaft deflection, installation misalignment, or thermal expansion. This reduces abnormal loads and extends component lifespan.
- Easy Installation & Maintenance: The integrated NU-LOC collar simplifies mounting, while the compact unit structure facilitates quick replacement and minimal downtime.
- Versatile Environmental Adaptability: The contact seal ensures reliable performance in dusty, humid, or contaminated environments, common in conveyor and agricultural machinery.
4. Application Scenarios
Widely used in general industrial equipment, the FONKIN NC206 is ideal for:
- Conveyor Systems: Belt conveyors, roller conveyors, and material handling equipment
- Rotating Machinery: Fans, blowers, and centrifugal pumps
- Specialized Machinery: Textile machinery, agricultural machinery (harvesters, tillers), and printing equipment
- Light Industrial Applications: Small gearboxes, electric motor supports, and packaging machinery
Its combination of self-alignment capability, easy installation, and robust load capacity makes it a cost-effective and reliable choice for medium-load, medium-speed drive systems where installation precision and maintenance efficiency are critical.
