Outer ring and roller assembly without separable inner ring
Available in 5 seal combinations (see page 75 also) The outer ring and roller assemblies are for use without inner rings on a ground shaft for which a minimum hard-
ness of 58 Rockwell “C” scale is recommended. 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 combina- tions, see page 75.

- This dimension may be slightly oversize due to seal press fit.
