This is a crankshaft bearing for US820, West Bend, Chrysler Power Bee 610 and 820 engines. It has CN internal clearance and an ABEC1 fit tolerance. It only has one seal that should face outwards so the bearing can be oiled by the premix. The seal can be removed if you want an open bearing.
This is also a new A 5 ball bearing that fits Albion 2 and 3 speed lightweight transmissions from 1931 to 1973. This is also correct for a Rokon or Nethercutt motorcycle that is equipped with an Albion 3 speed. The single seal should face the output sprocket. The seal can be removed if you want an open bearing.
One per purchase. The picture shows both sides.
Albion part number A 5
