Linear Unit QME- standard version

LOCALLY MANUFACTURED
By using Linear Unit QME from Rollco you save both time and money. The units are designed to fulfil the need of an easy to mount unit for medium precision requirements. The units are ready to mount linear tables guided with linear ball bearings on hardened shafts and driven by ball- or lead-screw. There is a wide variety of executions available for quick delivery from our workshop.

Selectable standard options are:
• Bellows
• Hand wheel
• Screw locking
• Mechanical position counter
• Left+Right drive units
• Magnetic end position switches

For higher level of corrosion resistance, low/high temperature versions, other screw-leads or
types, customized machining of the drive- and mounting-interfaces, contact Rollco.

Characteristics
• Linear ball bearings used for lowest friction and minimal and persistent play.
• Low backlash ball screw, optional with reduced backlash or backlash eliminated by light preload.
• Customized mounting flange for motor and/or customized end-machining of the screw shaft available.
• Corrosion resistant version as option.
