Technical information on rod ends

Rod ends, maintenance-free

Features

Maintenance-free rod ends and maintenance-free corrosion-resistant rod ends comprise a housing with integral shank and a maintenance-free spherical plain bearing. The shank has an internal or external thread, the spherical plain bearing is firmly seated and located in the housing.

The rod ends are available in open designs and in designs sealed on both sides. The housings and shanks are protected against corrosion by a zinc coating.

The sliding layer between the inner ring and outer ring is PTFE composite , ELGOGLIDE or PTFE film .

Area of application

Maintenance-free rod ends can support radial loads in a tensile or compressive direction. They are particularly suitable for slow movements with small to moderate swivel angles and unilateral loads. For alternating loads, rod ends with bearings of series GE..-UK-2RS(-2TS) and GE..-FW-2RS(-2TS) can be used.

Rod ends and hydraulic rod ends, requiring maintenance

Features

Rod ends requiring maintenance and hydraulic rod ends incorporate spherical plain bearings with a steel/steel sliding contact surface. Schaeffler can also supply spherical plain bearings with a steel/ bronze sliding contact surface.
Rod ends requiring maintenance

Rod ends requiring maintenance comprise a housing with integral shank and a spherical plain bearing requiring maintenance. The shank has an internal or external thread, the spherical plain bearing is firmly seated and located in the housing.

The rod ends are available in open designs and in designs sealed on both sides. The housings and shanks are protected against corrosion by a zinc coating.

Area of application

Rod ends requiring maintenance can support radial forces in a tensile or compressive direction and can transmit motions and forces with low moment levels. They are particularly suitable for alternating radial loads and, in certain circumstances, for unilateral loads. The thin walled design of the eye housing allows compact adjacent constructions.

Rod Ends

Rod ends are spherical plain bearing units. They comprise a housing and integral shank, into which a spherical plain bearing is integrated, and have an external or internal thread. Rod ends are used as connecting levers and connecting rods and as connecting elements between cylinders and their adjacent parts in hydraulic and pneumatic cylinders.

The rod ends can support radial forces in a tensile or compressive direction. They are suitable for slow movements with small to moderate swivel angles, for unilateral load and under certain conditions for alternating loads.

Rod ends are available maintenance-free as a standard design and as corrosion-resistant rod ends made from high-grade steel as well as with CETOP mounting dimensions.
