Family specifications and selection conditions
| Product description | Insert bearings in the YET 2 series, supplied with already fitted rubber seating rings. Located between the bearing outer ring and housing bore, the rubber seating ring dampens vibration and noise and enables the bearings to be displaced slightly in their housings and to accommodate minor shaft expansion or misalignment. |
|---|---|
| Manufacturer features | Quick and easy to mount onto the shaft • Accommodate static initial misalignment • Long service life • Reduced noise and vibration levels |
