Smith-Trax idler-roller bearings with tapered roller or deep-groove ball bearings are designed to handle both heavy radial loads and thrust loads without skewing and failing at high speeds. These maintenance-free bearings are lubricated for life, and have special seals to keep out sand, moisture and other heavy-industry contamination. They are manufactured in stud styles for fast installation and in yoke styles for maximum load capacity. Produced in inch and metric sizes, they come in four configurations, plain, flanged, v-grooved and u-grooved, to suit a wide range of applications.
