# Keep W609RS1/VP311 Separate From W619

Look-alike part numbers are the usual way a stores ticket goes wrong on a stainless steel bearing for micro motors. Do not substitute W619, W629, or W639 2RS1/VP311/VT811 variants collected in the same title. The public Model NO. is W609RS1/VP311. RS1 is a contact seal; do not assume an open or ZZ micro-motor bearing is the same part.

W609RS1/VP311 is listed as a stainless steel bearing for micro motors. 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.

Review W609RS1/VP311 bearing 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.
