- Screw support can be selected as standard option via the option number.
- A maximum of two screw support pairs is possible.
- High speed over long lengths of up to 5400 mm.
- Guide of the screw supports in the main body.

- Screw supports are protected by optionally selectable sealing strip.

Integrated Measuring System for MKK-080-NN-3, MKK-110-NN-3 and MKK-140-NN-3
The IMS-A measuring system offers the following advantages:
- No additional space required.
- No external mounting surfaces required for the measuring system.
- No measuring inaccuracies due to deviations in parallelism between the measuring system and the guide system
- Full integration of the measuring system components into the guide means no complex assembly or tuning work is needed
- The runner block, measuring head and guide rail with scale can be replaced individually during servicing.
- Interfaces: HIPERFACHE or DRICE-CLiQ.
- Connection cable directly on the side of the carriage.

Motor attachment with mount and coupling
A motor can be attached via a mount and coupling to all linear modules equipped with a ball screw drive.
The mount serves to fasten the motor to the Linear Module and acts as a closed housing for the coupling.
The coupling transmits the motor drive torque free of distortive stresses to the Linear Module’s drive shaft.
Our standard couplings compensate for the system’s thermal expansion.

1 Motor
2 Mount
3 Coupling
4 Linear module
Motor attachment via timing belt side drive
On all linear modules with a ball screw drive the motor can be attached via a timing belt side drive.
This makes the overall length shorter than when attaching the motor with a mount and coupling.
The space-saving, closed pulley housing provides protection for the belt and acts as a motor bracket.
In addition, various gear ratios are available.
The timing belt side drive can be mounted in four different directions.

1 Pulley housing made of anodized aluminum
2In some cases with support bearing for Rexroth Ball Screw Assembly screw journal.
3 Linear module
4 Belt drive with gear ratio: i = 1; i = 1,5; i = 2
5 Servo motor
6 Pre-tensioning of the belt drive: Apply preload force Fpr to the motor (Fpr is stated upon delivery).

Technical data
General technical instructions
Note on dynamic load capacities and load moments
Determination of the dynamic load capacities and load moments is based on a travel life of 100 000 m. Often only 50 000 m is actually stipulated.
For comparison:
Multiply values C, Mt and ML from the table by 1.26.
Suitable loads
Regarding the desired nominal life, in general loads for Fcomb, Fm up to around 20 % of the dynamic characteristic values (C, Mt, ML) have generally proven suitable.
See the "Calculation" document in the "Project planning instructions" chapter for the respective Linear Module.
Do not exceed the technical data for the Linear Motion System.

Permissible drive torque
The values for Mp apply for the following conditions:
- Screw journal without keyway
- No radial load on screw journal
Caution: Screw journal with feather key groove
For reasons of stress concentration and a reduction of the effective diameter, observe the maximum value Mp = 48 Nm for drive torque! (applicable to ball screw drive 32x20 and 32x32)

Permissible speed vmax

| 1) | without screw support |
Deflection
Take note of the "General Technical Instructions" section of the "Technical Data" chapter.
Example
Linear Module MKK-080: L = 3000 mm, F = 1500 N
From diagram MKK-080: f = 1.8 mm, fmax = 3.5 mm
The deflection f is significantly less than the maximum permissible deflection fmax, and no additional support is therefore necessary.
The following diagram is valid for:
- both ends firmly fixed (200 to 250 mm per side)
- 6 to 8 screws per side
- solid mounting base
- Lmax must be noted; see the "General Technical Data" table in the "Technical Data" chapter

General information
The linear modules are mounted using various fastening elements:
- Clamping fixtures
- Sliding blocks for size -110 and up
- Square nuts
- Spring nuts
- Screws for T-slots as per DIN 787 (no picture).
Length depends on base.
When mounting Linear Modules, please note the maximum tightening torques listed in the table.

Proximity sensors, mechanical switches and accessories (MKK/MKR/MLR)
Mounting instructions:
The mechanical switches, the proximity sensors and the socket with plug and cable channel are fastened with attachments in T-grooves of the main body. Switch activation is carried out by a switch bracket on the carriage.

Socket and plug, cable duct
Attach the socket to the side with the most switches. The socket and plug are not pre-wired. The variable sliding attachment allows switching positions to be optimized during start-up. The plug can be mounted in three directions.
Cable duct
The cable duct is fastened in the T-slots on the side of the frame. Fastening screws widen the profile and ensure that the cable duct is securely mounted.
See the illustration for the position of the slot.
The cable duct will accommodate up to two cables for mechanical switches and three cables for proximity switches.
Fastening screws and cable grommets are included.

Mounting examples of switches
Determination of the switching position
Switching distance: The switching distance is the distance between the carriage center (TM) and the zero point (0) when a switch is actuated (indicated in mm). Example of a mechanical limit switch (assuming the zero point is at L/2):
Maximum switching distance = 0.5 x (max. travel distance) – excess travel = 0.5 x effective stroke
For safe operation of the linear module the excess travel must be greater than the braking path.
For MKR... and MLR...: The acceleration travel sa can be assumed as the reference value for the braking distance.
For MKK...: In most cases, the following is sufficient as a guideline value for the excess travel (braking path): Excess travel = 2 x screw lead P.
Note the smallest possible switching distance (determined by attachments):
mechanical-mechanical = 60 mm; mechanical-proximity = 45 mm; proximity-proximity = 28 mm.
for MKR-145: mechanical-mechanical = 62 mm; mechanical-proximity = 49 mm; proximity-proximity = 35 mm
The switches as well as socket with plug are fixed in the upper T-slots of the frame and actuated by a switch tab on the carriage.
