Key Features

Area of application: For high torsional moments on rails

The same high load ratings in all four main directions of loading

Long-term lubrication is possible over several years

Excellent dynamic characteristics

Attachments on the ball runner block can be mounted from above and below

High torque load capacity

Integrated all-round sealing

Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block

Can be used on all BNS ball guide rails

Wide range of accessories

End-face fastening thread for all attachments

Lube connection with metal thread on all sides

Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection

Maximum system rigidity due to preloaded O-arrangement

Very high torsional moment load capacity and very high torsion resistance – therefore primarily used as an individual guide

Ball runner block pre-lubricated at the factory

Description

The ball runner block is highly precise and characterized by the following product features: Size 25 Format BNS: Width = wide, length = normal, height = standard Runner block body made of unalloyed steel CS Preload class C1: Low preload Accuracy class N: Standard Without ball chain With initial lubrication and preservation Roller bearing grease Dynalub 510 Without attachment element, left (front reference edge) Without attachment element, right (front reference edge) Straight lube connection loosely attached. Runner block body in standard version Overall length of the runner block = 105.0 mm Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.
