722500G

Flexible Flange Housings

The flange bearing housings of the 722500G and FCMG series represent an evolution of classic housings with felt seals. Manufactured according to the modular principle, these housings allow the use of common split and unsplit seals and covers. These seals or covers are attached within the housing using a retaining ring, enabling versatile customization. The inclusion of split seals provides a wide selection while reducing inventory requirements. The retaining ring can also serve as a centering feature, adding further flexibility to the application.

Benefits

Optimized Performance

722500-G flange housings improve assembly and allow the use of split seals. Low-friction 2-lip seals prevent contamination and support higher speeds. Drill holes allow for easy relubrication.

Fill the bearing's free space completely with grease, and the housing's free space to 20-40% volume. Use 40% grease fill for side relubrication, and 20% for outer ring relubrication. In highly contaminated or slow-speed environments, fill the housing to 70–80%.
