This bearing housing serves as a stabilisation ring for fix bearing arrangements. The outside diameter is 250.0 mm and the net mass is 138.16 g, matching the FRM250/5 designation from FAG. The ring is fitted to secure the axial position of the bearing within the housing bore, keeping the fixed bearing seated correctly under load. Its dimensional match to the 250.0 mm bore ensures a stable fit without additional machining, and the low mass reflects a slim ring profile suited for direct mounting alongside the bearing it stabilises.
