Description All metal parts are made from corrosion-resistant steel All plastic parts are made from certified materials Excellent dynamic characteristics The same high load ratings in all four main directions of loading Can be used on all SNS Ball Guide Rails Features Long-term lubrication is possible over several years Lube fittings with metal threads on all sides Limitless interchangeability as all Ball Rail Systems can be combined at will with all Ball Runner Block versions within each accuracy class. Maximum system rigidity due to pre-tensioned O-arrangement End-face fastening thread for all attachments High rigidity in all load directions – permits applications with just one runner block per rail Integrated all-around sealing Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection Smooth, quiet running thanks to optimally designed ball return and guidance Attachments on the Ball Runner Block can be mounted from above and below Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the Ball Runner Block Product description Material specifications Technical data Load capacities and load moments Size 15 20 25 30 35 C N 5100 12300 15000 20800 27600 C0 N 9300 16900 21000 28700 37500 Mt Nm 63 205 270 460 760 Mt0 Nm 90 215 295 500 805 ML Nm 34 110 150 245 375 ML0 Nm 49 115 165 265 390 The calculation of the dynamic load ratings and load moments is based on a stroke length of 100,000 m as per DIN ISO 14728-1. However, often only 50,000 m is actually stipulated. For comparison: Multiply the values C, M t and M L from the table by 1.26.

These can be drilled open. c) Lube nipple, sizes 15 – 20: Funnel-type lube nipple DIN 3405-A M3x5, B2 = 1.6 mm When using different lube nipples, observe the screw-in depth of 5 mm! Lube nipple, sizes 25 - 35: Hydraulic-type lube nipple DIN 71412-A M6x8, B2 = 9.5 mm When using different lube nipples, observe the screw-in depth of 8 mm! The lube nipple is included in the scope of delivery (not installed). Connection possible on all sides. d) Sealing plugs maybe present at this position for manufacturing reasons.
