6320/C3 SING ISB deep groove ball bearing

ISB 6320 C3 Deep Groove Ball Bearing (SING)

The ISB 6320 C3 is a high-performance, single-row deep groove ball bearing with an open design, engineered for extreme radial loads. As a member of the robust 6300 series, it offers superior load-carrying capacity in its size class. The increased C3 internal clearance ensures reliable operation at high speeds and elevated temperatures, effectively preventing seizure caused by the thermal expansion of massive 100 mm shafts.

Application

• High-Power Electric Motors: Stable support for heavy rotors in the energy and mining sectors.
• Heavy Industrial Pumps and Fans: Performance in systems with high dynamics and substantial load density.
• Main Gearboxes: Reliable radial force transmission in heavy-duty drive systems.
• Agricultural and Construction Equipment: Durability for main drive shafts in crushers and harvesters.
• Heavy Mechanical Systems: Support for drive drums in large-scale material handling systems.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 6320 C3
• Type: Single-row deep groove ball bearing
• Design: Open (requires oil or grease lubrication within the housing).
• Internal Clearance: C3 – radial clearance greater than normal.
• Series: 6300 (Heavy-duty reinforced series).

Note: Standard dimensions for the 6320 are 100 mm (Bore) × 215 mm (OD) × 47 mm (Width).

Features and Benefits

• Maximum Durability: The massive ring architecture supports loads that lighter series (6000, 6200) cannot withstand.
• Thermal Stability (C3): Enables reliable performance at temperatures exceeding standard operating norms.
• Open Configuration: Facilitates free lubricant flow and efficient heat dissipation from the massive raceways.
• Low Friction: ISB precision grinding reduces rolling resistance, leading to lower energy consumption.
• High Fatigue Life: Manufactured from high-purity hardened steel to ensure long-term mechanical integrity.

Why Choose This Product

The ISB 6320 C3 bearing is a cornerstone of reliability for your most critical machinery. In large-scale applications, any failure leads to massive downtime costs – choosing a proven ISB product is an investment in production continuity. The C3 clearance provides a vital safety margin wherever friction and heat could affect system geometry, ensuring smooth performance for thousands of operating hours.
