1. Precision Dimensional Parameters
Bore Diameter (d): 15 mm (Tolerance: 0 / -0.008 mm)
Outside Diameter (D): 40 mm (Tolerance: 0 / -0.011 mm)
Width (B): 11 mm (Tolerance: 0 / -0.120 mm)
Chamfer Dimension (\(r_{\min }\)): 0.6 mm
Precision Class: ISO P6 / ABEC-3 standards ensure minimized radial runout and vibration.
2. Advanced Material Metallurgy
Rings & Rolling Elements: Premium-grade AISI 52100 (100Cr6) high-carbon chromium bearing steel, through-hardened to 60–64 HRC. This material delivers superior wear resistance, high fatigue strength, and extreme dimensional stability.
Cage Retainer: Engineered from Glass-Fiber Reinforced Polyamide 66 (PA66-GF25) or pressed steel, optimized for low inertial forces, high elastic limits, and reliable self-lubricating properties.
3. Core Manufacturing & Processing Technology
Precision Forging & Turning: Optimizes metallic grain flow to enhance structural integrity.
Martensitic Heat Treatment: Eliminates internal stresses, ensuring dimensional stability up to 120°C.
Superfinishing & Grinding: High-precision grinding and super-lapping reduce raceway surface roughness (\(R_a \le 0.08\,\mu\text{m}\)), minimizing friction coefficients and heat generation.
4. Service Life & Dynamic Load Ratings
Basic Dynamic Load Rating (\(C\)): 11.4 kN
Basic Static Load Rating (\(C_{0}\)): 5.4 kN
Fatigue Life Standard: Calculated per ISO 281 (\(L_{10}\) life), exceeding 20,000 operational hours under standard loads (\(P \le 0.1C\)).
Lifespan Factors: Highly dependent on proper lubrication sealing, contamination prevention, and alignment accuracy.
5. Target Industries & Core Applications
The structural design of the FONKIN CAR40 makes it ideal for high-speed, low-vibration environments:
Automotive Aftermarket: High-efficiency automotive alternators, belt tensioners, and electric cooling fans.
Industrial Automation: Electric power tools, high-frequency spindles, and robotic joints.
Precision Machinery: Conveyor rollers, small gearboxes, and textile machinery.
6. Maintenance & Lubrication Protocols
Lubrication: Factory pre-filled with high-performance lithium-complex synthetic grease (30%–35% free space fill).
Maintenance Cycle: Sealed variants (2RS/ZZ) are maintenance-free. Open variants require inspection every 5,000 hours.
Inspection Standards: Monitor for abnormal noise via vibration analysis and check for housing temperature spikes (\(>85^{\circ }\text{C}\)).
7. Engineering Installation & Safety Standards
Pre-Assembly: Clean shaft and housing bores. Keep the bearing in its protective wrap until installation to avoid dust contamination.
Mounting Method: Use mechanical press-fitting tools or induction heating (do not exceed 110°C). Never apply impact forces directly to the outer ring.
Alignment & Torque: Maintain axial misalignment under 0.002 radians. Fasten locking components with calibrated torque wrenches to avoid ring distortion.
