88509 Double Sealed Bearing

8000 87000 88000 Felt Series Ball Bearings for air tools and contaminated environments.
Applications where dirt exclusion and lubrication retention are primary considerations. This series is designed
with an extended inner race to meet the exact dimensions of the felt series. Varying the contact pressure of the lip
seal allows these bearings to be used for extremely high speed as well as for normal applications. The 88000 series,
identical to the 8000 and 87000 series, has the added advantage of a Buna N Seals on both sides of the bearing.
Identical in dimension to the felt series, this sealed bearing prevents contamination from entering the raceway.
