Outer ring and roller assembly
with separable inner ring
Available in 5 seal combinations (see page 69 also)
For a complete bearing, specify both outer and inner, as
each is packed and shipped separately. Consult McGill
Engineering Department for additional information on
CAGEROL® bearing sizes not listed as available with
seals. The suffix “SS” indicates double seals with lips
turned in (illustrated at right). This construction is most
common and is intended primarily for lubrication retention.
For other seal combinations, see page 69.
MCGILL MR-16-SS,MI-12 Nots
