Special features:
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 with minimum curve radii that make them ideal for building sealed constructions.
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.
All substances are registered according to the REACH regulation. REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) ensures that users have accurate information on the type and properties of operating materials, lubricants, etc. that they might come into contact with.

High load-carrying capacity for minimum effort! Linear Guide Rail PS 4-20 is especially easy to anchor in the Line 8 groove of a support profile. Simply put the 20 mm-wide Rail in position and screw it into place – no further machining required. Push the corresponding Bearing Carriage PS 4-20 onto the Rail and it is ready for use.
Linear guide systems like this, which are based on a recirculating ball bearing guide, exhibit high load-carrying capacity and rigidity combined with excellent precision. The rows of balls have two-point contact and run on the raceway in a back-to-back arrangement at a contact angle of 45°. As a result, they can accommodate high loads and torque loads with low friction.
Linear Guide Rail PS 4-20 is up to 2960 mm long, features predrilled mounting openings and can be cut to any length. It is fixed in place using Assembly Set 8 PS 4-20.
The Carriage features four M5 threaded holes in the item modular dimension for attaching Line 6 and 8 profiles or a custom carriage plate. The ball bearing is low maintenance and durable.
Linear guide system PS 4-20 from item is a perfectly coordinated all-rounder that fills the gap between compact linear guide system PS 4-15 and exceptionally robust linear guide system PS 4-25.
