NTN angular contact ball bearings

Catalog references include 7000, 7001, 7205B and 7306B. Keep every numeric and letter block. These examples locate products in the line; an isolated letter does not establish a contact angle, adjustment or operating condition.

Transcribe any additional assembly identification from the packaging or drawing. If several bearings occupy the same position, record each reference and its order before separating them.

In pump shafts and machine tools, interpret the support as part of an assembly. Show the thrust direction and identify any other bearing involved in carrying it. Naming the equipment provides context but does not establish suitability for every reference in the family.

Photographs taken before dismantling preserve orientations that may be difficult to reconstruct later. Distinguish observations about the bearing from work on the housing, shaft or spacers; each contributes different information to the replacement enquiry.

Provide MR with the full NTN code, quantity and equipment position. Add a drawing or sketch showing adjacent supports. When several units belong to one assembly, explain that relationship instead of submitting an unexplained list of numbers. The review can then address the arrangement actually being repaired.
