High shock loads and severe contamination make rock and aggregate crushers among the toughest applications for precision components—particularly roller bearings. The harsh environments in which crushers operate present a big challenge to bearing performance and present a constant threat to long, reliable equipment life.
Keeping machine availability high and cost of ownership low in these conditions requires a commitment to proper care, including routine inspection and re-lubrication of roller bearings in compression and impact crushers. Knowing the common types of bearings used in crushing equipment can help operators and maintenance personnel understand how different designs impact performance.
