# Field Notes on inch and metric engine-accessory wheel hub
Inch and metric engine-accessory wheel hub is listed as a wheel hub bearing (inch and metric accessory duty). 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 engine-accessory and mixed inch/metric hub positions described on the page. Material on this listing is bearing steel. If your equipment sits outside that range, say so on the request rather than forcing a familiar part number.
Do not substitute a purchase based only on the generic title, without a measured bore, OD, and width. No public model code is given. Identify the hub from the vehicle or engine drawing and keep the inquiry tied to this exact product page.
Review inch and metric engine-accessory wheel hub 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.
