KML Square Bore Ag Bearing, 1-1/2X3.937X1.312X1.312

KML Square Bore Ag Bearing, 1-1/2X3.937

The KML W211PPB3 Square Bore Ag Bearing is a heavy-duty radial ball bearing engineered for severe contamination environments such as agricultural tillage equipment. It features Tri-Ply Seal protection with an exterior shroud cap that helps guard against lubricant loss and the intrusion of wet, abrasive debris, while also protecting seal components from wrappage and abrasion. Built with deep races, large balls, and extra-wide shock-resistant rings, this bearing delivers strong load capacity and added shaft support from its wide inner ring—ideal for demanding ag applications. (For speeds above 500 RPM, consult engineering guidance per manufacturer recommendations.)
