Profile Rail, 400 Series Ball Carriage, Size: 25 mm, High Precision Grade, E Style, 0 - Clearance Preload, Steel Alloy Description Polymer ball-return tube reduces noise and vibration while retaining lubrication Standard double lip end and longitudinal seals retain lubrication while protecting the bearing from contamination Lubrication channels that direct lubricant to individual ball tracks, maximizing lubricating effectiveness Double-faced ball tracks utilize a 45° face-to-face bearing arrangement, resulting in equal load-carrying capacity in all directions Carriages 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] 40.0 mm [B] 48.0 mm [B2] 12.5 mm [G] 9.0 mm [J] 34.2 mm [L] 79.2 mm [L1] 35.0 mm [L3] 57.5 mm [LN] 15.6 mm [M1] 14.2 mm [N] 35.0 mm [S1] M6 Performance 100 km Dynamic [Mx] Roll Moment 211 N·m (156 lbf·ft) 100 km Dynamic [My] Pitch Moment 169 N·m (125 lbf·ft) 100 km Dynamic [Mz] Yaw Moment 169 N·m (125 lbf·ft) 100 km Dynamic Load Rating 15,952 N (3,586 lbf) 50 km Dynamic [Mx] Roll Moment 267 N·m (197 lbf·ft) 50 km Dynamic [My] Pitch Moment 213 N·m (157 lbf·ft) 50 km Dynamic [Mz] Yaw Moment 213 N·m (157 lbf·ft) 50 km Dynamic Load Rating 20,100 N (4,519 lbf) Maximum Acceleration 50 m/s² (164 ft/s²) Maximum Velocity 5 m/s (16 ft/s) Static [Mx] Roll Moment 440 N·m (325 lbf·ft) Static [My] Pitch Moment 352 N·m (260 lbf·ft) Static [Mz] Yaw Moment 352 N·m (260 lbf·ft) Static Load Rating 41,100 N (9,240 lbf)
