Bosch Rexorth Linear module MKK-110-NN-3 R117529220

Types

Screw support (SPU) for MKK-080-NN-3, MKK-110-NN-3 and MKK-140-NN-3
The Screw Support (SPU) offers the following advantages:

• Screw support for horizontal applications (in preparation for vertical applications)

• 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 maintenance-free.

• 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.

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
