<p>Our 1" internal diameter (ID) pillow block and bearing comes as a matching set of two, complete with self-aligning double sealed chrome ball bearings, a cast iron housing, set screws, and grease fittings. Pillow blocks may be used to mount axles as well as a huge range of industrial applications, making them ideal for custom go-karts, trailers, and other projects where robust strength are required.</p>
<p>Note: Self-aligning bearings are adjustable. Simply mount the blocks, insert the axle or shaft through both, then tighten the set screws. There may be a bit of tolerance or play but this is by design to facilitate getting the bearing axis parallel.</p>
<p>Please refer to the photos and the specifications to determine whether these pillow blocks are just what you need.</p>
