Product description

Information

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

The bearing socket is made of a special bronze material which makes these rod ends 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 ends with PTFE surface, and therefore a higher life expectancy.
