Rubber seating rings in the RIS 2 series are primarily intended to cushion insert bearings in pressed steel pillow (plummer) block housings. Located between the bearing outer ring and housing bore, they dampen vibration and noise and enable the bearings to be displaced slightly in their housings and to accommodate minor shaft expansion or misalignment.
