Product Features
- Single-row deep groove ball bearing design supports radial loads and moderate axial loads in both directions. Simple and robust construction requires little maintenance and is suitable for high-speed applications.
- ZZ metal shields on both sides provide effective protection against ingress of dirt and contaminants while maintaining low friction for high running speeds.
- Ultra-compact miniature bearing design – ideal for applications where space is extremely limited, such as starter motors, alternators, and light-duty automotive components.
- Manufactured to OE specifications with chrome steel rings and balls for durability and fatigue resistance.
- Maintenance-friendly design with factory-preserved lubricant. The metal shields are non-removable and protect against contamination.
- Available for product customization – logo, code, pattern, or words can be applied to the bearing or packaging.
Installation Notes
- Confirm bore diameter (3.00 mm) and outer diameter (8.00 mm) match your housing and shaft before installation.
- This bearing is shielded on both sides – shields are non-removable and protect against contamination. Do not attempt to remove or disassemble the shields.
- Inspect the housing and shaft surfaces for wear or damage before installing new components.
- Apply even pressure when pressing the bearing into the housing or onto the shaft – never apply force directly through the rolling elements. Do not use a hammer to strike the bearing.
- Bearing is factory-lubricated – no additional greasing required before installation.
- Install in a clean environment to prevent contamination. Even small particles entering the bearing can shorten its service life.
