Ball runner block, FNS, size 15, aluminum, accuracy standard, low preload, with ball chain

The aluminum ball runner block is highly precise and has a reduced weight compared to the steel version. Additionally, it is characterized by the following product features:<br>Size 15<br>Format FNS: Width = flange, length = normal, height = standard<br>Runner block body made of aluminum<br>Preload class C1: Low preload<br>Accuracy class N: Standard<br>With ball chain<br>With initial lubrication and preservation<br>Roller bearing grease Dynalub 510<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 = 58.2 mm<br>Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy. Area of application: For lightweight design – for compensating low tolerances with connected structures Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection Extra-compact lightweight design 60% less gravity due to aluminum compared to the ball runner blocks made of steel Maximum precision Patented entry zone increases the travel accuracy up to a factor of six Ball chain for low noise level and best travel behavior High torque load capacity Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block Attachments on the ball runner block can be mounted from above and below Lube connection with metal thread on all sides Type-dependent: Ball runner block pre-lubricated at the factory Minimum quantity lubrication with integrated reservoir for oil lubrication Predrilled holes on the Ball Runner Block for pinned fitting Enables greater parallelism and height offsets of mounting bases Quiet, smooth running thanks to optimally designed ball and ball chain return and guideway Accuracy classes H and N are combinable with all rails in each accuracy class Long-term lubrication is possible over several years
