This is a brand new, old stock (NOS) NSK double row angular contact ball bearing, part number 5208-2RSTNC3.

This high-quality industrial bearing features durable rubber seals on both sides to keep lubrication in and contaminants out, an internal glass-fiber reinforced polyamide cage (TN), and a C3 internal clearance rating for optimal high-speed and thermal performance. The technical labels on the packaging indicate production or batch references AR3N5 and 810.

The bearing is entirely unused and in pristine condition with factory lubricant intact. It includes its original NSK Bearings cardboard box, which exhibits typical warehouse shelf wear, light cosmetic smudges, and age from long-term storage as pictured.
