Ball runner block, FLS, size 55, steel CS, accuracy super precision, high preload, without ball chain

The ball runner block is highly precise and characterized by the following product features:<br>Size 55<br>Format FLS: Width = flange, length = long, height = standard<br>Runner block body made of unalloyed steel CS<br>Preload class C3: High preload<br>Accuracy class SP: Super precision<br>Without ball chain<br>Preserved<br>Without initial lubrication<br>Without attachment element, left (front reference edge)<br>Without attachment element, right (front reference edge)<br>45° angular lube nipples loosely attached.<br>Runner block body in standard version<br>Overall length of the runner block = 199.0 mm<br>Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy. Area of application: For the most demanding rigidity requirements Heavy-duty Ball Runner Block for heavy machine construction with extremely high load-bearing capacity Maximum rigidity in all load directions Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block High torque load capacity Attachments on the ball runner block can be mounted from above and below Minimum lubrication quantities thanks to innovative channel design Smooth, quiet running thanks to optimally designed ball return and guideway Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection Different preload classes End-face fastening thread for all attachments Can be used on all SNS ball guide rails Limitless interchangeability as all ball guide rail versions can be combined at will with all ball runner block versions
