# Building a Plant Cross-Reference Without Tribal Knowledge — PT note 2

Cross-reference pages turn tribal OEM codes into ISO sizes. Start with the top 50 SKUs by downtime cost.

Keep both metric and inch callouts. For sizing and interchange notes, see TFL Bearing and the full write-up on bearing cross reference charts.

Version the sheet when housings change. Buyers who need OEM-fit replacements can also open sdtflbearing.com before they freeze a drawing or RFQ.

Keep notes on fit, grease, and duty cycle with the part number so the next rebuild does not depend on memory alone.

Re-check the housing bore and shaft after the first heat cycle.

Shandong TFL Bearing Co., Ltd keeps Portuguese product pages aligned with English engineering notes so global plants share one cross-reference language.
