Older instrument and military designations
Annular is the older term for a radial ball bearing, and it still appears on drawings and on parts that carry a national stock number instead of a modern catalog code. The few here are MPB and MRC units, including a 45x80x11/16 in size, a 1-7/8 x 2-7/16 x 1/4 in instrument size, and an ABEC 5 unit at 50x85x19 mm with a supply number stamped beside the catalog number. Because these designations predate current cataloging, measuring is the reliable route: bore, OD, width, and closure. Send those plus any stamped codes and we will work out what interchanges. Modern equivalents usually sit under deep groove ball bearings.
Our team can locate, cross-reference, and source all parts.
