The Timken (Fafnir) GN106KRRB Wide Inner Ring Insert Bearing is a heavy-duty agricultural ball bearing engineered for the toughest field conditions. Part of Fafnir’s heavier 300-series line, it carries higher continuous and shock loads than standard inserts and adds a thicker contact-type seal that fully retains lubricant while shutting out dirt and moisture, ideal for the slow to moderate speeds and abrasive conditions of hay, forage, and harvesting equipment. The wide inner ring supports and aligns the shaft, and the eccentric locking collar mounts quickly on straight shafts. A direct-fit replacement across Case-IH and other major agricultural brands.
