608ZZ Bearing Specification, Dimensions and Applications Guide
What is a 608ZZ Bearing?
The 608ZZ bearing is one of the most widely used miniature deep groove ball bearings in the world. It features double metal shields (ZZ) to protect the bearing from dust and contamination while allowing high-speed rotation.
608ZZ bearings are commonly used in:
- Electric motors
- Skateboards
- Power tools
- Household appliances
- Fitness equipment
Due to its compact size and high performance, the 608ZZ bearing is widely used across industrial and consumer products.
608ZZ Bearing Dimensions
The standard dimensions of a 608ZZ bearing are:
| Parameter | Value |
|---|---|
| Inner Diameter (d) | 8 mm |
| Outer Diameter (D) | 22 mm |
| Width (B) | 7 mm |
These dimensions follow international standards, making the 608ZZ bearing interchangeable with many global brands.
Load Rating of 608ZZ Bearing
Typical load ratings:
| Type | Value |
|---|---|
| Dynamic Load Rating | 3.45 kN |
| Static Load Rating | 1.37 kN |
The load capacity allows the 608ZZ bearing to perform reliably in high-speed and moderate-load applications.
Speed Limit of 608ZZ Bearing
Maximum speed depends on lubrication:
| Lubrication | Speed |
|---|---|
| Grease Lubrication | 34,000 RPM |
| Oil Lubrication | 40,000 RPM |
Proper lubrication ensures longer service life and reduced noise.
