Drop-in replacements need matching envelope, clearance, and cage style—not just a logo swap.

Compare load ratings and suffixes carefully. For sizing and interchange notes, see TFL Bearing and the full write-up on FAG vs TFL bearing comparison.

Pilot on non-critical shafts first. 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.
