6218-2Z ISB SING deep groove ball bearing

ISB 6218 ZZ Deep Groove Ball Bearing (SING)

The ISB 6218 ZZ is a high-performance single-row deep groove ball bearing, engineered for reliability in demanding industrial environments. As part of the 6200 series, it offers an excellent balance between load capacity and physical dimensions. Equipped with dual metal shields (ZZ), it provides a non-contact barrier against contaminants, which minimizes friction and supports high rotational speeds. The SING designation ensures delivery in original single-unit ISB packaging.

Application

• Large Electric Motors: Stable shaft support with minimal rolling resistance for high efficiency.
• Industrial Pumps and Fans: Ideal for continuous-duty equipment where low heat generation is critical.
• Heavy Machinery Gearboxes: Handling radial loads and moderate axial forces in both directions.
• Agricultural Equipment: Durable bearing support for drive shafts and auxiliary mechanical units.
• Production Lines: A component dedicated to systems requiring long maintenance-free intervals.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 6218 ZZ
• Type: Single-row deep groove ball bearing.
• Sealing: ZZ – non-contact metal shields on both sides.
