Flanged Metal Shielded Deep Groove Ball Bearings: Manufactured to the same principal sizes as standard bearings but fitted with metal shields, these bearings have an additional flange to allow fitting into housings flush against the shoulder of the flange. They are often used on steel tracks as guides and supports. The shields serve to offer protection to prevent ingress of debris and dust whilst retaining the grease within the bearing.
Benefits: Cost effective replacement bearing, Flanged design, Metal shielded
Flanged Radial Bearings like these are also used within machines like 3D Printers that have timing belts, and allow the belt to move and rotate while the edge holds the belt in place and keeps it from sliding off. Typically, two of these bearings will be used together to keep belts centred, but double-flanged bearings can also be used instead.
