Additional SpecialCharacteristics– Identical outer dimensions,

matching accessories andadd-on components to TypeCKK Compact Modules

– Optimal movement, high loadcapacity, and high rigiditythrough two integrated,pre-loaded ball rail guides

– High travel speed, with highprecision and low noise, overlengths up to 10,000mm

– Side-mounted aluminim profilesguide the toothed belt and sealout contaminants

– Adjustable switches over theentire travel range; switchactivation without switch cam(with switch cam for typeCKR 25-200)

Product Overview

Compact Modules are precision,ready-to-install linear systemsoffering high performance within acompact envelope combined withan economical price-to-performance ratio and fast delivery

Construction– Extremely compact precision

aluminum profile (main basestructure) with two integratedball rail guides for optimalmovement of heavy loads athigh speeds

– Ready-to-install CompactModules in selectable lengthsup to Lmax

– Aluminum carriage available intwo lengths, depending onapplication load

– Driven by a pre-tensionedsteel-cord reinforcedpolyurethane toothed belt

Optional Components– Maintenance-free digital servo

drive with integrated brake andpre-installed feedback

– Type LP gear reducer– HALL REED sensors– Socket with terminals for

connecting switches– Aluminum profile cable duct for

easy mounting of switches

Economical maintenance of theball rail guides through centralizedlubrication (grease) system.Access ports are on top of thecarriage and either side of theextrusion


Pilot bore and tapped mountingholes on drive end for simple motormounting

Precision alignment and securemounting of attachments thanks tothreaded bores and dowel pin holesin the carriage

Gear Reducer:A variety of gear ratios allows anoptimal match between the load andthe motor inertia:i = 3i = 5i = 10

Idler (non-driven) end with integralbelt tensioning system. Pulley ballbearings are lubricated for life

Overview of Compact Moduleswith permissible loads

In consideration of the desiredoperating life, general loads up to 20%of the dynamic values (C, Mt, ML ) havebeen shown as acceptable.

Acceptable Loads(Recommended values basedon experience and testing)

In this respect, do NOT exceed:– The maximum permissible load,– The permissible drive torque,– The permissible speed.

Construction of the Type LPGear Reducer

For all Compact Modules, a planetarygearbox can be installed via a flange.The flange serves as a mounting pointfor the gearbox to the Compact Moduleand as an enclosed housing for theconnection. This direct connectioneliminates the need for a coupling,minimizing torsional deflection.

Different gear ratios are available:i = 3 (for CKR 20-145 and

25-200 only)i = 5i = 10

Note for Dynamic Load Capacitiesand Moments (see table)

The determination of the dynamic loadcapacities and moments is based on100,000 m of travel.

However, in many cases, only 50,000is assumed.For this, the following comparisonapplies:Values C, Mt and ML from the tableshould be multiplied by 1.26.

Switch MountingOverview of the SwitchingSystemThe following switch types may beused with Compact Modules:– Magnetic field sensors

(Hall and Reed Sensors)– For CKR 25-200, mechanical and

inductive switches may also be used

Different switch types cannot, however,be used on the same side of theCompact Module.

Magnetic Field Sensor

Switching System:Magnetic Field SensorHall Sensor and Reed Sensor1 Socket and Plug2 Switch3 Cable Duct

(black anodized aluminum extrusion)

Magnetic field sensors aresuitable for speeds up to 2 m/s. Forsafety reasons, mechanical/inductiveswitches are to be used at higherspeeds (please inquire)!Short Stroke: Pay attention to thelength of the socket and switch!

Magnetic Field SensorMiniature switch with potted cable:Version:– Hall Sensor (NC/NO) or– Reed Sensor (Relay)Assembly Note:Switches may be on one side of thecompact module only (left or right), andand should only be installed after thecompact module has been installed onits base structure.

A cable duct is required to attach theswitches.

Switches are inserted in the upperT-slot (CKR 12-90, 15-110) or thelower T-slot (CKR 20-145, CKR25-200) of the cable duct andsecured with set-screws.

Socket and PlugThe socket must be installed on theside with the switches.

Sockets and plugs have 16 pins.

Sockets and switches are not wired.This allows optimal assignment of theswitch positions during set-up.

One plug is included. The plug can beinstalled in three directions.

Positioning Accuracy P The positioning accuracy is determinedby the total deviation. It includes allsystematic and random deviationsin positioning.

Position Deviation Pa The position deviation is determined bythe maximum occurring differencebetween the mean values of allmeasurement points. It describessystematic deviations.

Reversal Range U The reversal range is determined by thedifference in the mean values from bothdirections of approach. The reversalrange is calculated at eachmeasurement point. It describessystematic deviations.

Variation Range PS The variation range shows the effectsof random deviations. It is calculatedat each measurement point.

The positioning accuracy takes thefollowing values into consideration:– Postion deviation– Reversal range– Variation range

Positioning Accuracyper VDI/DGQ 3441Option 05Measurement points are selected atirregular intervals along the travel path.These points allow the capture ofperiodic positioning deviations.

Each measurement point isapproached several times,from both directions.

The excess travel must be greaterthan the braking distance. As aguideline, the breaking distance canbe estimated as two turns of themotor.

This can be calculated bymultiplying the lead constant of thepulley by 2, then dividing the resultby the gear reduction.
