Outer ring and roller assembly
without separable inner ring
Available in 5 seal combinations (see page 69 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 69.
