6308-2Z SING ISB deep groove ball bearing

ISB 6308 ZZ Deep Groove Ball Bearing (SING)

The ISB 6308 ZZ is a high-performance single-row deep groove ball bearing, engineered for demanding industrial environments. As a member of the 6300 series, it features more robust ring architecture and larger rolling elements than the 6000 or 6200 series. Equipped with dual metal shields (ZZ), it provides effective protection against solid contaminants without increasing friction torque, making it ideal for high-speed applications. The SING designation ensures the product is delivered in its original, single-unit factory packaging.

Application

• Electric Motors: Precise guidance for 40 mm shafts while maintaining low rolling resistance.
• Fans and Blowers: Capability to operate at high RPMs without excessive heat buildup.
• Industrial Gearboxes: Handling of large radial loads in continuous duty cycles.
• Agricultural Equipment: Robust construction resistant to shocks and harsh operating conditions.
• Centrifugal Pumps: Stable performance of rotating assemblies under moderate axial loads.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 6308 ZZ
• Type: Single-row deep groove ball bearing
• Sealing: ZZ – dual non-contact metal shields.
