F686ZZ 6x13x5mm Chrome Steel Flanged Deep Groove Ball Bearing

F686ZZ Flanged Miniature Ball Bearing – Compact, Versatile, and Built for Precision Motion

The F686ZZ Flanged Miniature Ball Bearing is engineered to save space while delivering reliable, low-friction performance. The built-in flange acts as a locating feature. It allows the bearing to seat firmly against a housing face. As a result, you eliminate complex machining and extra retention components.

For engineers, this design simplifies housing construction. It also speeds up assembly and improves axial positioning reliability. In addition, it reduces the risk of loosening during long-term operation.

Key Features

Simplified Mounting

The flange is the key feature of this bearing. It provides a precision-machined locating shoulder. This shoulder sits directly against the housing face and prevents axial movement under thrust loads.

In addition, the flange removes the need for a housing shoulder on the inner diameter. This allows simpler through-hole machining with higher accuracy.

As a result, you reduce machining cost and assembly time. At the same time, the bearing maintains stable positioning throughout its service life.

High Hardness, Wear Resistance, High Load

The F686ZZ is manufactured from high-carbon chrome steel (GCr15 / SAE 52100). It is through-hardened to achieve strong rolling contact fatigue resistance.

This material provides excellent wear resistance. It also ensures strong dimensional stability during operation. In addition, it supports heavy radial loads and moderate bidirectional axial loads.

Low Noise, Low Vibration

The F686ZZ is produced under low noise and low vibration standards. Optional versions reach up to ZV2 vibration class (P6 precision).

This low acoustic performance is important. It improves user experience in office equipment, medical devices, and precision systems.

Therefore, it is widely used in applications where quiet operation is required.

Versatile Load Handling

As a deep groove ball bearing, the F686ZZ primarily handles radial loads. However, it also supports axial (thrust) loads in both directions.

This bidirectional capability is especially useful. It performs well in gearbox shafts, motor spindles, and conveyor rollers.

In these systems, load direction often changes during operation. The bearing maintains stability even under these conditions.
