The answer to versatility in design.
For extra-special design needs, this unit incorporates a Tri-Ply bearing mounted in two stampings, riveted together with two o-rings.
Available in two basic size groups, one incorporating a 209 and the other a 211 bearing.
Both Size groups offer these features.

Dynamic alignment capability.
Shroud effect from close clearance of stamping to inner ring.
Relubrication.
One unit piece for ease of handling and assembly.
Fitting flange mates with outer ring milled recess, preventing possibility of outer ring circumferential movement.
Stampings are case hardened to minimize wear.
Units are equipped with nylon retainer, molded one-piece seals and patented notched outer ring seal grooves.
