Linear Motion System

Compact Modules

Compact Modules from Rexroth come complete with drive unit and controller. As plug and play solutions, they simplify machine designs and speed up the commissioning process. They cover the entire spectrum of mid-range to high-end assembly and handling applications. These linear motion axes can be supplied with screw drive, belt drive or direct linear motor drive and offer high dynamics, high load capacities, and high rigidity. Especially important for designers: Not only does Rexroth offer its Compact Modules in various sizes and in any desired stroke length, but also with optional extras.

Compact Modules with ball screw drive - CKK
- Maximum Length: up to 2.200 mm
- Maximum Speed: up to 1,3 m/s
- Load Capacities: up to 89.340 N

Benefits at a Glance:

Especially low profile thanks to centrally arranged ball screw drive
High positioning accuracy and repeatability due to ball screw drive with zero-clearance nut system
High travel speeds and high precision over long strokes thanks to ball rail systems, large screw diameters and leads, and double floating bearings
Easy motor attachment using locating feature and fastening threads
Switches can be positioned anywhere along the travel range: switch activation without cam
Low-cost maintenance ensured by one-point lubrication (grease) of ball rail systems and ball screw drive; lubrication points accessible from either side
Optimal running properties, high load capacities, and high rigidity, thanks to two integrated, zero-clearance ball rail systems

Compact Modules with toothed belt drive - CKR
- Maximum Length: up to 5.500 mm
- Maximum Speed: up to 5 m/s.
- Load Capacities: up to 56.530 N

Benefits at a Glance:

Optimal running properties, high load capacities, high rigidity, thanks to two integrated, zero-clearance ball rail systems
High travel speeds and highly precise, smooth motion over lengths of up to 5500 mm
Lateral aluminum strips for gap sealing and belt guidance
Switches can be positioned anywhere along the travel range: switch activation without cam

Compact Modules with linear motor - CKL
- Maximum Length: up to 2.800 mm
- Maximum Speed: 3 m/s.
- Load Capacities: up to 13.646 N

Benefits at a Glance:

High positioning accuracy and repeatability thanks to precise optical position sensing system
High travel speeds and high acceleration rate due to excellent dynamics of the ironless linear motor
One-point lubrication for easy maintenance of ball rail systems
Maintenance-free linear motor
