Provides the outer support element for the rolling bearing assembly, forming the housing seat into which the bearing unit is fitted. The bearing housing FRM170/14,5 has an outside diameter of 170.0 mm and a net mass of 221.37 g, matching the corresponding bearing to maintain correct radial positioning within the housing bore. This ring is machined to work as the mating housing component rather than as a load-carrying bearing itself, so its dimensional accuracy determines the fit and seating of the assembled unit. Correct mounting of FRM170/14,5 ensures proper alignment and stable support of the bearing it is paired with, keeping the outer race positioned as intended during operation.
