# Field Notes on S694ZZ stainless steel miniature deep groove ball bearing
S694ZZ is listed as a stainless steel miniature deep groove ball bearing. Because a public millimetre sheet is thin on some catalog pages, confirm bore, outside diameter, and width against your drawing or the live product listing.

Typical duty includes medical and other clean, moisture-aware miniature mechanisms. Material on this listing is stainless steel. If your equipment sits outside that range, say so on the request rather than forcing a familiar part number.
Do not substitute a chrome-steel 694ZZ or a nearby S693/S695 size. Shields (ZZ) and stainless rings are the usual reasons this model is chosen for medical-adjacent duty. Measure the miniature envelope before issuing stock.
Review S694ZZ on the TFL Bearing Made-in-China listing. Shandong TFL Bearing Co., Ltd can confirm stock, packing, and any OEM marking once the drawing or sample is attached.
