The FAG 6317-M-J20ABC4 EAN CODE 4012802 276060 is a high-performance single-row deep groove ball bearing, characterized by its enhanced load capacity, precise dimensional control and reliable operation, specifically designed for medium to heavy-load industrial applications. It integrates premium materials, advanced manufacturing technology and optimized structural design, fully complying with international bearing industry standards. The following is a comprehensive and concise technical overview.
1. Detailed Dimensional Parameters: Conforming to GB/T 274-2023 and ISO standards, the bearing has an inner diameter (d) of 85mm, outer diameter (D) of 180mm, and width (B) of 41mm. The chamfer size (r) is 2.1mm (minimum limit), with a tolerance grade of P0. Its basic dynamic load rating is 132kN, basic static load rating is 96.5kN, reference speed (grease lubrication) is 8000r/min, and limiting speed (oil lubrication) is 5300r/min. The suffix C4 indicates enlarged radial internal clearance, adapting to thermal expansion in high-temperature operations.
2. Specific Material Description: Inner ring, outer ring and rolling elements are made of high-carbon chromium bearing steel (AISI 52100/SUJ2), refined by vacuum degassing to reduce impurities. After precision heat treatment, it reaches a hardness of 60-64 HRC, featuring excellent wear resistance, fatigue strength and dimensional stability. The retainer (suffix M) is brass solid cage, with good thermal conductivity and impact resistance, ensuring stable operation at high speeds. The J20ABC denotes special internal structure optimization for enhanced load-bearing capacity.
3. Core Processing Technology: Key processes include closed-die forging, CNC turning, controlled atmosphere heat treatment, precision grinding and superfinishing. Closed-die forging ensures dense internal structure; CNC turning achieves Ra ≤ 0.4μm surface roughness. Heat treatment adopts nitrogen-hydrogen protective atmosphere to avoid oxidation, ensuring uniform hardness. Precision grinding with CBN砂轮 and superfinishing reduce raceway roughness to Ra ≤ 0.05μm, minimizing friction and noise.
4. Service Life: Under standard working conditions (3000r/min, radial load 35kN, proper lubrication), the L₁₀ basic rated life (90% reliability) is 18,000 operating hours, calculated in accordance with ISO 281 standard. Key influencing factors include lubrication quality, pollution level, installation accuracy and load magnitude; lubrication failure can reduce service life by 30-50%.
5. Application Scenarios and Industries: Widely used in mechanical manufacturing, petrochemical, agricultural machinery and electric power industries. Typical applications include large electric motors, generators, pumps, ventilation equipment and plastic processing machinery. It is suitable for these scenarios due to its high load capacity, C4 clearance for thermal adaptability and brass cage for high-speed stability.
6. Basic Maintenance Requirements: Maintenance cycle is 2000 operating hours. Lubrication: Lithium-based grease (NLGI 2), filling amount 15-30% of bearing free space; re-lubricate every 1500-2000 hours. Cleaning: Clean surface with clean gasoline to remove dust and old grease. Regular inspection: Check for abnormal noise, temperature rise and grease leakage; replace grease immediately if it turns black or deteriorates.
7. Installation Precautions: Pre-installation: Keep the area clean, remove burrs from shaft and bearing seat. Installation: Apply thin oil film on fitting surfaces, press evenly on inner ring (no tapping), ensure coaxiality tolerance ≤ 0.02mm. Fastening torque: 120-150N·m for bearing seat bolts. Post-installation: Rotate manually to check for jamming; normal operating temperature ≤ 70℃. Safety: Wear protective gloves and goggles; use special tools for handling.
