KML Bearing USA Agricultural Bearings are manufactured to meet the rigorous demands of planting, harvesting and processing machines.
KML Agricultural Bearings’ inner ring, outer ring and balls are produced using vacuum degassed 52100 bearing steel. These components are heat treat hardened to produce a durable wear surface on the balls and ball tracks. KML uses cold rolled steel for ball retainers and shields.
All KML disc harrow bearings and disc harrow units feature triple-lip sealing systems. The KML triple-lip system utilizes excluder seals that are positioned in series providing three lip contact areas with barrier channels between each lip. This design is effective in keeping the lubricant in and debris & moisture outside of the critical ball track areas.
All KML Agricultural Bearing Units are factory lubricated using Chevron SRI#2 grease with about 30-40% grease fill. Disc harrow units are designated as either factory sealed lube-for-life or regreaseable.
There are special size radial ball bearings in the Agricultural Bearings product line that duplicate custom part configurations that commonly occur in these pieces of equipment. These special size ball bearings have features such as inner ring extended on one or both sides, different seal configurations or non-standard bore, outside diameter or width. Additionally, bore shapes may be round, square or hexagonal.
