- 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)
