This ring provides radial stabilisation for a fixed bearing arrangement, acting as a housing element positioned around the bearing to secure its position within the assembly. Outside diameter is 170.0 mm, with a net mass of 76.34 g. The bearing housing ring is used where a fixed bearing must be held firmly in axial and radial position, preventing unwanted displacement during operation. It does not incorporate rolling elements or seals itself, functioning purely as a mechanical stabilisation component that works in conjunction with the bearing it supports.
