GN 291 Lineaariset toimilaitteet Teräs / ruostumaton teräs, oikea- tai vasenkätisellä kierteellä

The load data are applicable to linear actuators GN 291, GN 292, GN 293 made of steel (SCR) or stainless steel (NI).

The specified forces Fy and Fz cause a flexure of the guide tube of approx. 0.5 mm.

A lead nut moves in axial direction over the ball bearing trapezoidal thread spindle of the linear actuator. The follower ensures the anti-rotation and makes the link to the different linear actuator connectors. The linear actuators have been designed for manual operation (handwheel).

The positioning accuracy is 0.2 mm / 300 mm stroke, the maximum reverse play is 0.1 mm.

Guide tubes are available in chromed steel (SCR) or stainless steel (NI) non-rusting. They are made with the tolerance range of precision steel tubes DIN 2391 or DIN 2462.

A wide variety of different components are available in the tube clamp connector program to fix the linear actuators in place and to upgrade these into linear actuator connectors.

Also, digital position indicators (Asennonilmaisimet GN 953 / Asennonilmaisimet GN 954 / Asennonilmaisimet GN 9053 / Asennonilmaisimet GN 9054) may be attached to measure the displacement or the positioning.

In applications where high torsion forces Mx occur, linear actuators with square tubing or double tube linear actuators should be given preference.

A wide variety of different components from the tube clamp connector program is also available for the square tubings. The linear actuator connectors are composed of two-part elements, with the effect that the precision of the square tubes involves no special requirements.

Information
The longitudinal scales GN 299 of type A and B are normally used in connection with the linear actuators Lineaariset toimilaitteet GN 291 and Lineaariset toimilaitteet, neliömalli GN 291.1, the scales of type C and D are normally used for the linear actuators Lineaariset toimilaitteet GN 292 and Lineaariset toimilaitteet GN 293.

Longitudinal scales can only be ordered togehter with linear actuators.

Two parallel sliding linear actuators GN 291 are connected with a transfer unit GN 391.
The angular housings GN 298-W including the bevel gear wheels GN 297 and another transfer unit GN 391 connect the handwheel with the system. The handwheel is placed in a rectangular position to the moving axes.

Two flanged linear actuator connectors GN 146.1 are moved parallel. For this two linear actuators GN 291 are connected with a transfer unit GN 391.

The T- and angular gear GN 298-T/-W including the bevel gear wheels GN 297 and another transfer unit GN 391 connect the handwheel with the system. The handwheel is placed in a parallel position to the moving axes.
