Applications & Industrial Use
The SKF 628/8 ZZ is a compact deep groove ball bearing with double metal shields (ZZ), measuring 8 mm inner diameter x 16 mm outer diameter x 5 mm width. It is engineered for industrial applications that demand a dependable bearing unit in tight spaces. Typical uses include small motors, pumps, fans, precision automation equipment, micro-drives, and miniature gearboxes.
Thanks to its shielded design, this bearing unit resists contamination in dusty or low-maintenance environments, making it ideal for use in assembly lines, instrumentation, HVAC systems, robotics, and other industrial automation contexts.
Advantages & Key Features
-
Double metal shields (ZZ) protect the internal components while minimizing friction and preserving internal lubricant.
-
Low-friction design contributes to quieter operation and efficient energy use in rotating systems.
-
High durability built with precision steel and tight tolerances to resist wear over extended service life.
-
Compact footprint (8x16x5 mm) enables integration into small assemblies or where space is constrained.
-
Compatibility with bearing housings (bearing blocks or obudowa łożyskowa) makes mounting and replacement easier in modular systems.
-
Ready for use - factory-lubricated, requiring minimal maintenance and ideal for plug-and-play insertion in industrial assemblies.

FAQ - Frequently Asked Questions
1. What does “ZZ” indicate in the bearing designation?
“ZZ” denotes metal shields on both sides of the bearing. These shields block dust and debris while allowing minimal friction, helping maintain internal lubrication.
2. Can this bearing be used for high-speed applications?
Yes — the shielded version tolerates up to approximately 45,000 RPM, making it suitable for many small motor and precision drive applications.
3. What kind of loads can 628/8 ZZ bear?
It is designed primarily for radial loads, but can also support light axial loads in both directions, thanks to its deep groove geometry.
4. Does the bearing require additional lubrication after installation?
No — it is factory-lubricated and sealed. The shields help retain lubricant, so typically no further lubrication is necessary under normal conditions.
5. How quickly can I receive delivery?
