6701-ZZ Thin-Section Deep Groove Ball Bearing For Small Fans | 12×18×4 Mm

The 6701-ZZ is a Thin-Section Double-Shielded Deep Groove Ball Bearing engineered for applications where radial space is extremely limited. Featuring the standard deep groove raceway design with a remarkably low cross-section, this bearing provides reliable radial load support in a compact form factor. With a 12 mm bore and only 4 mm width, and equipped with double metal shields (ZZ), it is an ideal solution for small fans, office machinery, precision instruments, and other compact assemblies where minimizing overall dimensions is critical, without compromising on protection or performance.



6701-ZZ Deep Groove Ball Bearing 12x18x4 mm | Thin Series | Double Metal Shields (ZZ)

Key Performance Features

01. Ultra-Low Profile Design

The thin-series (67-series) construction provides full bearing functionality in a minimal axial width, saving critical space in compact assemblies while maintaining adequate radial load capacity for light-duty applications.

02. Integrated Shielded Protection

Comes standard with double metal shields (ZZ), offering effective protection against dust and debris ingress. This design is ideal for applications where re-lubrication is not feasible and a sealed-for-life unit is required.

03. Smooth Operation in Confined Spaces

Manufactured to standard tolerances for thin-section bearings. The precision components ensure smooth, low-noise rotation, providing reliable performance even in space-constrained environments where heat dissipation and airflow may be limited.
