6313-2RS C3 SING ISB deep groove ball bearing

ISB 6313 2RS C3 Deep Groove Ball Bearing (SING)

The ISB 6313 2RS C3 is a high-performance single-row deep groove ball bearing designed for heavy-duty industrial environments. As part of the 6300 series, it features larger rolling elements and more robust rings, offering significantly higher load ratings than the 6000 or 6200 series. Equipped with contact rubber seals (2RS) and increased C3 internal clearance, it is optimized for high thermal stress and exposure to contaminants. The SING designation ensures delivery in original, single ISB factory packaging.

Application

• High-Power Electric Motors: C3 clearance prevents ball seizing during shaft thermal expansion.
• Industrial Pumps and Fans: NBR seals provide an effective barrier against moisture and vapor.
• Heavy Gearboxes and Drives: Stable handling of large radial loads while maintaining smooth rotation.
• Agricultural Equipment: High resistance to external contaminants like dust, dirt, and debris.
• Manufacturing Systems (MRO): Extended service life that minimizes maintenance downtime.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 6313 2RS C3
• Type: Single-row deep groove ball bearing
• Sealing: 2RS – dual contact rubber seals (NBR).
• Internal Clearance: C3 – radial clearance greater than normal.
• Series: 6300 (Reinforced load capacity).

Note: Standard dimensions for the 6313 model are 65 mm (Bore) × 140 mm (OD) × 33 mm (Width).

Features and Benefits

• Reinforced Architecture: Capable of supporting much higher forces than the standard 6213 series.
• 2RS Sealing System: Protects internal components from water and grit, making the bearing maintenance-free.
• Thermal Stability: C3 clearance ensures reliable operation at elevated temperatures and high rotational speeds.
• Low Friction & Quiet: Precision-ground raceways ensure minimal vibration and acoustic noise.
• Ready to Install: Factory-filled with high-grade lubricant for its entire service life.

Why Choose This Product

The ISB 6313 2RS C3 bearing is the ultimate choice for critical industrial systems requiring maximum uptime. When standard bearings struggle with high loads or thermal expansion, this model provides the necessary safety margin. By choosing ISB, you invest in high-end European engineering that reduces operational costs and ensures the smooth performance of your heavy-duty equipment.
