Product Description Smoother than smooth— the balls inside these bearings roll nearly friction- free. The sturdy housing bolts down to support shafts as they turn. Lubricate regularly to keep your bearing in tip-top shape. Bearings with seals and shields keep lubricants in and contaminants out, and come packed with grease. Open bearings require initial lubrication and offer less protection against dust and debris. Aluminum Housing — One-third the weight of cast iron but not as strong. Aluminum also resists corrosion. Press Fit — For a tight connection to the shaft, install with a press or by heating and then cooling the bearing. Also known as an interference fit.
