EC210B D6E TCD2012 main bearing 02931580 04284642 20850106
D6E main bearing STD is machined by scraping. Change the direction each time you scrape so that the scratches form a 60° or 90° angle. Continue to gradually increase the contact points for several times, and finally the color spots are evenly distributed until the specified standard is reached. Our 02931580 bearing has sufficient compressive strength, fatigue strength and the ability to withstand impact.
