SKF 63800 ZZ Deep-Groove Ball Bearing 10x19x7 mm

Main Description

The SKF 63800 ZZ is a finely engineered deep-groove ball bearing designed for space-limited applications where both performance and compactness matter. With dimensions of 10 mm inner diameter, 19 mm outer diameter, and only 7 mm width, this bearing belongs to the thin-section class, offering a slim profile without sacrificing strength or longevity.

Thanks to the metal shields (ZZ) on both sides, the bearing is protected from dust and contaminants while retaining lubrication. This results in reduced maintenance needs and excellent reliability in continuous operation. The shielded design ensures consistent performance with minimal friction, making it suitable for high-speed and low-noise environments.

This bearing is particularly useful in precision industrial applications — such as compact gearboxes, robotic drives, automation units, medical devices or any mechanism requiring a durable miniature bearing. It can be integrated into bearing units or small housings, supporting radial loads efficiently and maintaining long-term operational stability.

The high-grade steel construction ensures long service life and smooth rotation, even under challenging operating conditions. Its thin-section design allows designers to save space and reduce overall assembly weight while benefiting from SKF’s renowned quality and reliability.

FAQ

1. What does the "ZZ" designation mean?
“ZZ” indicates that the bearing has metal shields on both sides, providing protection against dust and retaining the lubricant.

2. Is this bearing suitable for high-speed applications?
Yes — the thin-section design and quality steel construction make it well-suited for high-speed and low-friction environments.

3. Where is this bearing typically used?
Ideal for compact mechanical systems such as precision gearboxes, robotics, industrial automation, small motors, and instrumentation.

4. Does the bearing require additional lubrication?
No — it comes pre-lubricated from the factory and the metal shields help retain the grease, reducing maintenance needs.

5. Can it support axial loads?
While primarily designed for radial loads, it can handle moderate axial loads due to its robust deep-groove design.
