Bearing 629 ZZ shielded ball bearing 9x26x8 mm - replacement part

Shielded ball bearing 629 ZZ is a single-row deep groove bearing designed for radial load applications in small motors and household appliances. The bearing has double metal shields on both sides, providing protection against dust and moderate contamination while maintaining low friction and smooth rotation. Its compact dimensions—9 mm inner diameter, 26 mm outer diameter and 8 mm width—match standard 629 size bearings used as replacement parts in vacuum cleaners, fans and other compact rotating assemblies.

Advantages

The double metal shields (ZZ) reduce the ingress of dust and debris without the need for contact seals, helping to preserve lubricant and extend service life in moderate operating environments. The deep-groove geometry supports reliable radial load performance and simple installation due to the standard dimensions. Low rolling resistance and stable rotation characteristics contribute to quieter operation and efficient motor performance.

Suitable for

• Replacement bearing in small electric motors
• Vacuum cleaner rotating assemblies and brush modules
• Household appliances with compact bearings (fans, mixers, blenders)
• Small gearboxes and hobbyist mechanical devices

Key specifications

• Bearing type: single-row deep groove ball bearing
• Shielding: double metal shields (both sides)
• Inner diameter: 9 mm
• Outer diameter: 26 mm
• Width: 8 mm
• Typical application: radial load support, moderate contamination environments

How to use

Ensure the bearing seat and shaft are clean and free of burrs before installation. Press the bearing onto the shaft or into the housing using an even force applied to the inner ring when fitting on a shaft, or to the outer ring when fitting into a housing, to avoid damaging the shields and internal components. Do not apply force to the shields. Check alignment and axial clearance according to the appliance manufacturer’s instructions. If replacing an existing bearing, inspect housings and shafts for wear and replace any damaged components to ensure proper fit and function.

Usage recommendations

Use this 629 ZZ shielded bearing in applications with moderate contamination and where occasional maintenance or re-lubrication is possible. Avoid prolonged exposure to water or heavy contamination; for wet or heavily contaminated environments consider bearings with contact seals or additional external protection. Store bearings in a dry, temperature-stable environment and handle them with clean tools to preserve lubricant and prevent premature failure.
