# Confirming W609RS1/VP311 Before the Housing Is Opened

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.

Typical duty includes micro motors and other compact stainless, sealed positions. 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 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.

Review W609RS1/VP311 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.
