63mm Solid Series 25 (Ungeared)

SUN25 Series Solid Section Ungeared

The ungeared bearings in this series have a constant height of 63mm only as both rings are of equal size. However, the bolt and pilot diameters equal those of the geared bearings which can be useful if a range of machines requires flexibility in design for powered or unpowered versions. Tolerances are machined to IT9 grades.
