Overview
The F688ZZ bearing is a metric-size miniature flanged deep groove ball bearing with metal shields on both sides (ZZ) for dust and particle protection. Its compact design, precision construction, and integrated flange make it ideal for applications that require accurate axial positioning and easy mounting in confined spaces.
-
Bearing type: Deep groove ball bearing
-
Shield type: ZZ (double metal shields, non-contact)
-
Bore diameter (d): 8 mm
-
Outer diameter (D): 16 mm
-
Flange outer diameter (Df): 18 mm
-
Width (B): 5 mm
-
Flange thickness (Df1): 1.1 mm
The flange acts as a positioning shoulder, allowing for secure axial mounting without additional components.
Key Features & Benefits
-
Precise axial positioning – The flange prevents axial movement and ensures stable alignment.
-
Simplified installation – Easy to mount and disassemble, reducing assembly time and maintenance costs.
-
Shielded protection (ZZ) – Metal shields help keep out dust and contaminants, extending bearing life.
-
Smooth rotation with low friction – Designed to reduce energy loss and improve efficiency.
-
Durable construction – High-quality steel ensures long service life even under continuous operation.
Common Applications of F688ZZ Bearings
Thanks to its small size, flange support, and shielded protection, the F688ZZ bearing is widely used in:
-
Automation & Robotics – robotic arms, precision gears, and linear guides
