Because the demands on America’s farmers are as great and varied as our Heartland itself, KML Bearing USA stocks many additional special size Ag Ball Bearings. These special size ball bearings duplicate custom part configurations that commonly occur in agricultural pieces of equipment associated with planting, harvesting and processing machines. These special size radial ball bearings have special features including:
- Non-standard bore types such as hex, square and round
- Different seal configurations such as metal trash seals, rubber seals and double & triple lip seals
- Extended inner rings on one or both sides
- Outside diameters and widths
- Gothic arch races
KML Bearing USA Agricultural Bearings feature the same basic construction as our Metric Single Row Deep Groove Radial Ball Bearings. All of the inner rings, outer rings and balls of KML Bearing USA’s Ag Ball Bearings are produced from vacuum degassed 52100 bearing steel. After production, they are heat treat hardened to produce a durable wear surface on the balls and ball tracks. All ball retainers and shields are manufactured from cold rolled steel.
Similar to other Single Row Deep Groove (SRDG) ball bearings, KML Bearing USA’s Ag Ball Bearings are lubricated with Chevron SRI#2 from the factory. As a high temperature ball and roller bearing grease, it’s formulated using a synthetic poly urea ashless organic thickener with additional rust and oxidation inhibitors. As such, this grease provides protection in severe applications, harsh agricultural environments and where incidental contact with both salt and fresh water may occur.
Since KML Bearing USA Ag Ball Bearings are factory lubricated, they are considered lubed-for-life, but grease deteriorates over time. Environmental conditions coupled with operating temperature, especially in hot, dry, rugged agricultural applications, help to speed-up this deterioration process. During high operation periods, KML Bearing USA advises to spot check Ag Ball Bearings on a regular basis.
