# Field Notes on SP-12FL stainless steel ball transfer unit
SP-12FL is listed as a stainless steel ball transfer unit. 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.
Contents
Typical duty includes conveyor and transfer-table systems. 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 SP-8FL, SP-15FL, or SP-22FL, which are listed on the same family page title. This page is SP-12FL only. A larger or smaller FL unit will change the pass line and the hole pattern.
Review SP-12FL 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.
