THE WN 648 self-lubricating rod-end bearings,now available in inch sizes, are for control and link mechanisms in all types of machines. These RoHS-compliant bearings are designed for high-load, low-speed applications with hanging angles, requiring linear, rotational, or oscillatory motions. Available in both tapped and threaded-stem versions, the bearings are made of zinc-plated low-carbon steel, with right or left-hand threads. The ball socket is low-carbon, zinc-plated, case-hardened steel. The external ring is a special oil-impregnated bronze material, which makes the rod ends self-lubricating and maintenance-free.
