DescriptionPolymer ball-return tube reduces noise and vibration while retaining lubricationStandard double lip end and longitudinal seals retain lubrication while protecting the bearing from contaminationLubrication channels that direct lubricant to individual ball tracks, maximizing lubricating effectivenessDouble-faced ball tracks utilize a 45° face-to-face bearing arrangement, resulting in equal load-carrying capacity in all directionsCarriages available with two internal configurations: standard ball bearings only (411), or premium ball cage added (413). When compared to the 411 design, the 413 option provides increased travel smoothness, lower noise at high speeds, and individual lubricant reservoirs. Both configurations are designed to run on the same rail (421)Dimension[A]42.0 mm[B]60.0 mm[B2]16.0 mm[G]10.0 mm[J]35.0 mm[L]64.2 mm[L3]37.2 mm[LN]15.6 mm[M1]8.0 mm[N]40.0 mm[S1]M8Performance100 km Dynamic [Mx] Roll Moment151 N·m (111 lbf·ft)100 km Dynamic [My] Pitch Moment64 N·m (47 lbf·ft)100 km Dynamic [Mz] Yaw Moment64 N·m (47 lbf·ft)100 km Dynamic Load Rating11,666 N (2,623 lbf)50 km Dynamic [Mx] Roll Moment191 N·m (141 lbf·ft)50 km Dynamic [My] Pitch Moment81 N·m (60 lbf·ft)50 km Dynamic [Mz] Yaw Moment81 N·m (60 lbf·ft)50 km Dynamic Load Rating14,700 N (3,305 lbf)Maximum Acceleration50 m/s² (164 ft/s²)Maximum Velocity3 m/s (10 ft/s)Static [Mx] Roll Moment350 N·m (258 lbf·ft)Static [My] Pitch Moment150 N·m (111 lbf·ft)Static [Mz] Yaw Moment150 N·m (111 lbf·ft)Static Load Rating27,000 N (6,070 lbf)
