# When a Polymer Bushing Beats a Sealed Ball Bearing

Oscillating farm and construction joints often kill seals. Polymer bushings with grease grooves last longer there.

The selection article compares the three joint types. For sizing and interchange notes, see joint selection notes and the full write-up on TFL Bearing bushing guide.

Check PV limits for the polymer. Buyers who need OEM-fit replacements can also open Read bearing vs bushing 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.
