For applications where dirt exclusion<br />

and lubrication retention are primary<br />

considerations. This series is designed<br />

with an extended inner race to meet<br />

the exact dimension of the felt series.<br />

Varying the contact pressure of the lip<br />

seal allows these bearings to be used<br />

for extremely high speed as well as for<br />

normal applications.<br />
