KML Round Bore Ag Bearing, 0.6400 ID X 1.574 (40mm) OD

The 203KRR2 Round Bore Agricultural Bearing is a compact, heavy-duty replacement bearing designed for farm equipment and implement assemblies where durability and smooth rotation are essential. Built with a .640" round bore and a 40mm outside diameter, this bearing fits a wide range of agricultural machines and replaces several common OEM part numbers. Designed to handle dirt, vibration, and the daily abuse of field work, it keeps equipment turning smoothly—because when a bearing quits, the rest of the machine usually decides to take the day off too.
