# Bearing Temperature Limits Before You Call an Alarm

Most greases live happily below about 70–80°C on the outer ring. Past that, oxidation and clearance loss accelerate.

Know the difference between brief peaks and steady rise. For sizing and interchange notes, see TFL Bearing and the full write-up on how hot is too hot for a bearing.

Log load and speed with the temperature. 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.

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