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.

Description

The compact Roller Guide with the best load-to-size ratio of all item drive elements.
•Light, quiet-running rollers arranged in a criss-cross pattern for high speed
•Innovative track technology – high-strength steel tracks rigidly connected to the aluminium guide profile
•Solid, rigid sliding carriage with a broad range of attachment options and integrated timing-belt clamp profile
•Drive Unit with internal reversing mechanism to give the smoothest possible movement when working with low moving mass
•Three Profile 8 grooves on three sides of the KRF guide profile ensure unbeatable flexibility for attachment geometries
•Simple adjustment with minimum maintenance requirements, all elements externally accessible
•Axes of customised length, guide length up to max. 6000 mm
•Motors can be adapted using universal coupling elements in the Drive Set
Linear Unit KRF is augmented by a range of useful accessories that enable simple attachment of slide constructions and drive modules.
Eight rollers, arranged play-free in a criss-cross pattern, ensure maximum load-carrying capacity with compact size.
The maximum deflection, fmax of the system is governed by the dimension of the profile cross-section, the free profile length and the force applied. It should not exceed 1mm/m. The KRF profile must be given appropriate support if the linearity of movement has to be very precise.
Complete Linear Units with variable stroke length (H), Drive Unit and Reverse Unit, support profile with integrated Roller Guide on guide tracks, preset free of play. Timing-belt tensioning device integrated into Reverse Unit, ball-bearing-mounted pulleys.
Guide slide with eight-piece roller-bearing mounting, oil-lubricated roller contact (re-lubrication every 6 months or every 2500 km)
Acceleration: max. 10 m/s²
Stroke velocity: max. 10 m/s
Linear Unit KRF boasts exceptional precision and low-vibration linear movement. Repeat accuracy is ± 0.1 mm.
The mass of a Linear Unit KRF can be determined from the stroke length (without payload):
m = m1 + H x m2
h = horizontal orientation
v = vertical orientation
Maximum possible acceleration in relation to moved mass and installation orientation
Travel speed v in relation to input speed n (timing-belt drive)
Operational force Fx dependent on input torque M (timing-belt drives Fx > 500N)
