6315-2Z/C3 SING ISB deep groove ball bearing

ISB 6315 ZZ/C3 Deep Groove Ball Bearing (SING)

The ISB 6315 ZZ/C3 is a high-performance single-row deep groove ball bearing engineered for extreme radial loads and high-speed efficiency. Part of the heavy-duty 6300 series, it features larger rolling elements than the 6000 or 6200 series, providing superior load-bearing capacity. Equipped with dual metal shields (ZZ) and increased C3 internal clearance, it is perfectly suited for high-temperature and high-RPM environments. The SING designation ensures original single factory packaging.

Application

• Large Electric Motors: C3 clearance accommodates shaft thermal expansion during continuous duty.
• Industrial Gearboxes: Reliable support for shafts in heavy-duty machinery.
• Industrial Pumps and Blowers: ZZ shields reduce energy loss by eliminating contact friction.
• Mining and Agricultural Equipment: Robust construction built for harsh operating conditions.
• Power Generators: High rotational stability and long service life.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 6315 ZZ/C3
• Type: Single-row deep groove ball bearing
• Sealing: ZZ – non-contact metal shields on both sides.
• Internal Clearance: C3 – radial clearance greater than normal.
• Series: 6300 (Reinforced load capacity).

Note: Standard dimensions for the 6315 model are 75 mm (Bore) × 160 mm (OD) × 37 mm (Width).

Features and Benefits

• Superior Load Rating: The massive architecture of the 6300 series handles forces that standard series cannot support.
• Zero Contact Friction: Metal ZZ shields protect against debris without slowing down the bearing, preventing heat buildup.
• High Limiting Speed: Optimized for high-speed industrial drives due to the combination of ZZ shields and C3 clearance.
• Maintenance-Free: Factory pre-greased for its entire service life, ensuring immediate installation readiness.
• Industrial Durability: Manufactured from high-purity bearing steel to resist fatigue and material wear.

Why Choose This Product

The ISB 6315 ZZ/C3 bearing is the ultimate choice for critical industrial systems requiring maximum uptime. When standard bearings struggle with thermal stress or high loads, this model provides the necessary safety margin. By choosing ISB, you invest in high-end European engineering that reduces maintenance costs and ensures smooth operation of heavy-duty equipment.
