Agricultura operates in some of the most punishing environments for machinery. Dust, dirt, shavure, and crop aros ever- present, and no consident bears thee brunt quite like bearings. A single grain of sand can exacleate wear by an order of magnitude, turning a precisision assemble into source of downtime. Selecting the right bearding for contribur machinery in dusty conditions is no just about picking a part ber is about.

If thee exterior is muddy, clean with a soft brush and a water- based cleaner, then dry.

Lubricant Replacement and- Re- Greasing

For re- greasable bearings with graase fittings (Zerk), thee schedule depends on dutt load. As a rule, re- grease every 100- 200 hour in dusty conditions, using a hightety agricultural graase (e.g., NLGI # 2 witch extreme pressure additives).
