Frequently Asked Questions

Q: What does "ZZ" mean in the bearing model number?

A: "ZZ" indicates that the bearing has two metal shields (one on each side). These shields protect the internal ball and raceway components from dust, dirt, and debris while retaining the factory grease — making them ideal for enclosed or semi-sealed environments.

Q: What material are these deep groove ball bearings made from?

A: These JARBLUE bearings are manufactured from GCr15 high-carbon chromium bearing steel, a standard material known for its excellent hardness, wear resistance, and fatigue life in both radial and axial load applications.

Q: How do I choose the correct bearing size (e.g., 6900-ZZ vs. 6905-ZZ)?

A: Select your size based on the inner diameter (ID), outer diameter (OD), and width required for your application. For example, the 6900-ZZ measures 10 × 22 × 6 mm, while the 6905-ZZ measures 25 × 42 × 9 mm. Match these dimensions to your shaft diameter and housing bore for a proper fit.

Q: Are these bearings suitable for high-speed applications?

A: Yes. Deep groove ball bearings in the 69xx ZZ series are designed for moderate-to-high rotational speeds, making them a popular choice for electric motors, power tools, and precision equipment. Always verify the rated RPM for your specific model against your application's requirements.
