WN 648 Rod End Bearings Steel, with Threaded Stem

WN 648 Steel Rod End Bearings with Threaded Stem

Product description

Rod end bearings WN 648 are used in controlling and linking mechanisms in all types of machines. Suitable for high load, low speed applications with hanging angles, requiring linear, rotational or oscillatory motions.

The bearing socket is made of a special oil impregnated bronze material which makes these rod end bearings self-lubricating, maintenance-free, and guarantees lowest friction. In addition, these rod end bearings have less increase of clearance after longer operating hours than rod end bearings with PTFE surface, and therefore a higher life expectancy.
