J.W. Winco Inc. offers WN 648 self-lubricating rod end bearings in inch sizes. Rod ends are used in controlling and linking mechanisms in all types of machines. These RoHS-compliant rod end bearings are suitable for high-load, low-speed applications with hanging angles, requiring linear, rotational or oscillatory motions. They are offered in both tapped and threaded stem versions.

The rod end bearings are made of zinc-plated, low-carbon steel, with right- or left-hand threads. The ball socket is low-carbon, zinc-plated steel, case hardened. The external ring is made of a special oil impregnated bronze material, which makes these rod ends self-lubricating, maintenance-free, and guaranteed lowest friction. In addition, these joints have less increase of clearance after longer operating hours than rod ends with PTFE-surface outer races, and therefore higher life expectancy.
