Believe this was part of a spherical roller bearing assembly.
Believe this was made in the 1950s or early 1960s, but possibly earlier.
My father acquired it at some point, and some place, prior to 1966, when we moved from the Trenton area.
My father was a machinist in the Navy in the 1940s, and may have worked as a machinist afterwards. Later, he worked as a historian, in the Trenton area.
RBC Bearings, in West Trenton, began operations in 1919.
Below is information about the company, from their website. This could have been part of a bearing assembly used on the CH-47, Chinook, or CH-46, Sea Knight helicopters, but I'm not at all sure.
