INA 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.
INA rod ends requiring maintenance
INA 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
INA 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.
INA rod ends, Dimension series E
INA rod ends to DIN ISO 12240-4, dimension series E incorporate radial spherical plain bearings GE..-DO or GE..-DO-2RS(-2TS) and have a right or left hand internal or external thread. The sliding contact surface is formed by steel inner and outer rings.
INA rod ends, Dimension series K
INA rod ends to DIN ISO 12240-4, dimension series K incorporate radial spherical plain bearings GE..-PB and have a right or left hand internal or external thread. The sliding contact surface is formed by steel inner rings and bronze outer rings.
Sealing
Sealed rod ends have the suffix 2RS or 2TS. They are protected by lip seals on both sides against contaminants and water spray. Rod ends GIR..-DO-2TS, GIL..-DO-2TS, GAR..-DO-2TS and GAL..-DO-2TS are sealed on both sides by integrated, triple lip high performance seals. Rod ends of dimension series K are not sealed.
INA Hydraulic rod ends
INA Hydraulic rod ends incorporate radial spherical plain bearings GE..-LO or GE..-DO. The sliding contact surface is formed by steel inner and outer rings. The rod ends can be screw mounted using a thread in the shank or welded in place by means of circular or rectangular welding faces.
INA Rod ends GIHRK..-DO and GF..-DO are also available with maintenance-free spherical plain bearings of series GE..-UK, GE..-UK-2RS(-2TS), GE..-FW or GE..-FW-2RS(-2TS).
INA Rod ends GIHRK and GIHNRK are slotted on both sides up to diameter d <= 50 mm. Rod ends GIHRK are slotted on one side from d >= 60 mm and rod ends GIHNRK are slotted on one side from d >= 63 mm.
Area of application
INA Hydraulic rod ends can support radial forces in a tensile or compressive direction and can transmit motions and forces with low moment levels. They are also suitable for alternating radial loads.
INA hydraulic rod ends with thread clamping device
The spherical plain bearings used are located in the rod end by means of retaining rings. A thread clamping facility comprising two hexagonal socket screws to DIN EN ISO 4762 is present on the threaded shank.
INA rod ends GIHNRK..-LO conform to DIN 24338 and ISO 6982. They are used in standard hydraulic cylinders to CETOP recommendation RP 58 H and to the standards DIN 24333, DIN 24336, DIN ISO 6020-1 and DIN ISO 6022.
INA rod ends GIHRK..-DO are particularly suitable for hydraulic cylinders. They have very small linkage distances with maximum stroke utilisation.
INA hydraulic rod ends with welding face
INA rod ends of series GK..-DO conform to DIN ISO 12240-4. They have a circular welding face, a locating pin on the shank base and a 45° welding chamfer. These rod ends are suitable for fixing to piston rod ends and cylinder bases. The spherical plain bearings are located in the rod end by staking on both sides.
INA rod ends of series GF..-DO are available in a heavy-duty design with a rectangular welding face. They are suitable for fixing to hydraulic cylinder bases. The spherical plain bearings are located in the rod end by retaining rings and can be dismounted.
Sealing
INA rod ends with integrated spherical plain bearings GE..-DO-2RS or GE..-FO-2RS are protected by lip seals on both sides against contaminants and water spray.
INA rod ends with integrated spherical plain bearings GE..-DO-2TS or GE..-FO-2TS are sealed on both sides by integrated, triple lip high performance seals.
