Many cast bronze bearings have flanges or shoulders as options. The flange is designed to aid in mounting and positioning. Flanges are also used with bearings on external housings. Flanged bearings are designed to handle both radial and thrust loads.
The flange bushing has 5 distinctive parts. The inner diameter (ID), the outer diameter (OD), the overall length of the bushing (OAL), the flange outer diameter (FLOD), and the flange thickness (FLTH).
