• High feed system power
• Rexroth precision ball screw assembly in rolled design tolerance grade T7 in accordance with DIN 69051 with backlash-free cylindrical nut
• High traversing speed due to large leads

Features

• Inexpensive maintenance thanks to the one-point lubrication (grease lubrication) on two sides of the guide system
• With bellows cover
• Simple motor mounting using centering recess and thread
• Wide range of accessories available

Product description

Linear motion slides are an inexpensive solution for a wide variety of applications. Linear motion slide guides consist of linear bushings that ensure quiet travel and a long service life. Linear motion slides with an open design are fastened to the mounting base using shaft support rails.

Switch mounting arrangements

The switching position indicates the position of the carriage center (TM) after moving. The zero point is at L / 2.

Maximum switching position

= 0.5 · travel path max. – excess travel

For safe operation of the Linear Motion Slide, the excess travel must be greater than the braking distance.

The acceleration travel can be adopted as the guideline value for the braking distance.

Recommended standard configuration:

• 2 mechanical switches

• 1 proximity switch

Push the mounting plates with switches into the slot and secure with the screws and square nuts.

Observe the lowest possible switching distance:

mechanical / mechanical = 62 mm

mechanical / proximity = 49 mm

proximity / proximity = 35 mm

Attention: For this, the mounting plates must be mirror-inverted.

Mounting side of the switches:

1 Socket with plug

2 Proximity switch

3 Mechanical switch

4 Switching cam

5 Profiled support

Switch mounting:

• Adjust the distance dimensions for the mechanical and proximity switches during assembly.

• In case of special operating conditions (vibrations, switches in the middle of the travel path), support the profiled support if necessary.

Dimensions mechanical switch (mm)

Dimensions proximity switch (mm)

Determine switching position

The switching position is derived from:

• Mounting side:

The switches can be attached on the left (L) or right (R).

• Direction of travel:

The switches can be attached on the minus (–) or positive (+) range.

• Switching distance:

The switching distance is the distance between the carriage center (CC) and the zero point (0) when a switch is activated (given in mm).

Example

Effective stroke = 500 mm

Limit switch:

Switching position 1st switch = + 250 mm

Switching position 3rd switch = – 250 mm

Positioning switch:

Switching position 2nd switch = – 150 mm

Length L

For calculation of the length, see "Length calculation" in the section “Dimensions”.
