Roller runner block, FNS, size 55, steel CS, accuracy super precision, average preload

The roller runner block is highly precise and characterized by the following product features:<br>Size 55<br>Format FNS: Width = flange, length = normal, height = standard<br>Runner block body made of unalloyed steel CS<br>Preload class C2: Medium preload<br>Accuracy class SP: Super precision<br>Without roller chain<br>Preserved<br>Without initial lubrication<br>Without attachment element, left (front reference edge)<br>Without attachment element, right (front reference edge)<br>Straight lube connection loosely attached.<br>Runner block body in standard version<br>Overall length of the runner block = 170.7 mm<br>Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy. High torque load capacity The same high load ratings in all four main directions of loading Maximum rigidity in all load directions due to additional screw connections on two bore holes in the center of the Roller Runner Block Unrestricted interchangeability All guide rail versions can be combined at will with all roller runner block variants Accessories can be screwed down to the front of the Roller Runner Block. Lube nipples possible on all sides for easy maintenance Minimum lubrication quantities thanks to innovative channel design Smooth, quiet running thanks to optimally designed return and guideways of the rollers Attachments on the Roller Runner Block can be mounted from above and below Lowest elastic deflection and greatest precision in the process due to the multi-optimized entry-zone geometry and high number of rollers The roller runner block is simply slid onto the rail with the transport lock.
