6316/C3 SING ISB deep groove ball bearing

ISB 6316 C3 Deep Groove Ball Bearing (SING)

The ISB 6316 C3 is a high-performance, single-row deep groove ball bearing with an open design, engineered for extreme radial loads. As part of the 6300 series, it provides significantly higher dynamic load ratings than lighter series for the same shaft diameter. The increased C3 internal clearance ensures reliable operation at high rotational speeds and elevated temperatures, effectively eliminating the risk of seizure caused by the thermal expansion of the shaft. The SING designation guarantees delivery in original single-unit factory packaging.

Application

• High-Power Electric Motors: Stable support for heavy rotors under intense thermal stress.
• Industrial Pumps and Fans: Performance in high-flow systems with significant dynamic loads.
• Heavy-Duty Gearboxes: Reliable radial force transmission in production machinery drives.
• Agricultural and Construction Equipment: Durability for main drive shafts in harvesters and crushers.
• Energy Sector: Bearing support for generators and turbines requiring high-grade service life.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 6316 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 (Reinforced load capacity).

Note: Standard dimensions for the 6316 are 80 mm (Bore) × 170 mm (OD) × 39 mm (Width).

Features and Benefits

• Maximum Load Capacity: Massive rings and large balls allow for safe operation under substantial stress.
• Thermal Stability (C3): Enables operation at temperatures where standard clearance bearings would fail.
• Open Configuration: Facilitates free lubricant flow and efficient heat dissipation from the raceways.
• ISB Precision: High-quality raceway finishing ensures smooth rotation and vibration reduction.
• High Durability: Use of high-purity hardened bearing steel ensures excellent resistance to material fatigue.

Why Choose This Product

The ISB 6316 C3 bearing is a cornerstone of reliability for your industrial equipment. In heavy-duty applications where shaft temperatures rise during operation, C3 clearance is vital for maintaining production continuity. By choosing ISB, you invest in European precision that lowers the total cost of ownership (TCO) by extending maintenance intervals and reducing unscheduled downtime.
