Detailed Product Information
Design & Protection
The 608Z features the classic deep groove raceway design, enabling it to carry significant radial loads and moderate axial loads in both directions. The integrated steel shield on one side offers a robust defence against dust and larger particles, making it a reliable choice for applications where complete sealing is not critical but basic contaminant exclusion is desired. For enhanced protection, we can provide variants with shields on both sides (608ZZ) or contact rubber seals (608-2RS).
Performance Characteristics
This bearing is renowned for its high-speed capability and smooth running. Its balanced design ensures low vibration and friction, contributing to energy efficiency and long service life. While supplied in standard commercial grades, our manufacturing expertise allows us to produce the 608Z to P5 and higher precision levels, ensuring exceptional running accuracy for demanding applications.
Applications
The 608Z is one of the most common bearing sizes, found in countless devices and machinery, including:
- Electric Motors: Small AC/DC motors, cooling fans, and appliance motors.
- Power Tools: Drills, grinders, and saws where high-speed operation is key.
- Material Handling: Conveyor rollers, pulleys, and light-duty gearboxes.
- Sports & Leisure: Inline skates, skateboards, and fishing reels.
- Office Machinery: Printers, scanners, and photocopiers.
