Technical Data

item products are based on different modular dimensions and their associated system grooves.Profiles from Lines 5, 6, 8, 10 and 12 each need corresponding sizes of fasteners.The profiles in Line X feature a Line 8 system groove but have a particularly flat surface withminimum curve radii that make them ideal for building sealed constructions.All substances are registered according to the REACH regulation.REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) ensures that usershave accurate information on the type and properties of operating materials, lubricants, etc.that they might come into contact with.Components that are RoHS-compliant contain no dangerous substances such as lead or cadmium.EC Directive 2002/95/EC (RoHS 1) restricts the use of certain substances in electronic devices and components.These include batteries, etc.

Excellent repeat accuracy and high drive forces – Linear Unit LRE 8 D10 80x80 KGT 20x5 is ideal for all applications that involve high operational forces and require exceptional precision. The low lead of the spindle translates a low drive torque into a high operational force. The use of roller guides D10 ensures that a payload of up to 90 kg can be carried – despite its small size.
h = horizontal orientation
v = vertical orientation
Travel speed v in relation to input speed n (ball screw, chain and rack drives)
Operational force Fx dependent on input torque M (ball screw drive, chain drive, rack drive)
