626-2Z ISB deep groove ball bearing

ISB 626 ZZ Miniature Deep Groove Ball Bearing

The ISB 626 ZZ is a high-precision, single-row deep groove ball bearing with miniature dimensions. It is engineered for applications requiring high dynamics and smooth motion where mounting space is strictly limited. Equipped with dual metal shields (ZZ), it provides an effective barrier against dust without increasing rolling resistance, enabling the bearing to achieve exceptionally high rotational speeds.

Application

• Small Electric Motors: Perfect for cordless power tool drives and robotics.
• Precision Equipment: 3D printers, scanners, and high-end office machinery.
• RC Modeling: High RPM capability and lightweight design ideal for RC vehicle drives.
• Computer Fans & Cooling: Ensures quiet operation and long service life in thermal management systems.
• Home Appliances: Small kitchen robots, blenders, and personal care devices.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 626 ZZ
• Type: Miniature deep groove ball bearing.
• Sealing: ZZ – Non-contact metal shields on both sides.
