GRW - Miniature duplex bearings

The GRW - Miniature duplex bearings consist of two precisely matched bearings mounted as a set. This configuration provides increased rigidity, improved accuracy, and optimal load distribution. Duplex bearings are commonly used in applications where single bearings do not deliver sufficient performance, such as in cases involving high axial loads or where maximum positioning accuracy is required.

Enhanced rigidity and precise load handling

By combining two bearings in specific arrangements—such as back-to-back (O), face-to-face (X), or tandem configurations—GRW miniature duplex bearings can efficiently accommodate both radial and axial loads. This results in greater system stiffness and stable operation, even at high speeds. The predefined preload minimizes internal clearance, ensuring consistent performance and high precision. These characteristics make them particularly suitable for applications such as spindles, precision instruments, and advanced machinery.

Flexible configurations and high-quality materials

GRW offers miniature duplex bearings in a wide range of configurations, with precise matching between the bearing pairs. Depending on your application requirements, you can select from various ring and ball materials, including high-grade bearing steel and corrosion-resistant options. Ceramic balls are also available, offering advantages such as lower friction and higher suitability for high-speed applications. In addition, a variety of lubrication options, sealing solutions, and tolerance classes are available to fully tailor the bearings to your specific operating conditions.

Thanks to this flexibility and precision, GRW duplex bearings provide a reliable solution for demanding applications where performance and consistency are essential.
