Compact Rail

Compact Rail - Linear Rails with Radial Ball Carriages

Compact Rail is a linear system consisting of steel linear rails with induction-hardened raceways and high-precision ball bearing radial carriages made of hardened steel. Thanks to their self-aligning features, Compact Rail linear guides simplify the project, increase performance, and reduce the overall application cost. Compact Rail linear guides can be easily mounted on all types of surfaces, including unmachined ones.

Compact Rail linear guides feature a robust steel carriage with ball bearings, self-centering heads equipped with scrapers, longitudinal seals to protect internal components, and an upper sealing strip. The carriage body has a matte longitudinal edge chamfer and a precisely ground, shiny flat surface. The carriage heads are equipped with special flexible felt pads and are free to rotate so as not to impede the movement of the carriage, ensuring the felts are always in contact with the raceways to provide optimal lubrication. The felts can be lubricated only via a syringe lubricator through a special grease filling port located on the front of the head.

The raceways are located within the C-profile and are therefore protected from foreign substances. Additionally, the seals on the carriage and the different available anti-corrosion treatments make the Compact Rail linear guides reliable even in more demanding environments.

Key Features

• Self-aligning systems on two planes: axial up to 3.9 mm, radial up to ±2°
• High dynamic performance thanks to ball bearings (V= 9m/s, A=20m/s2)
• Optimum reliability in dirty environments.
• Long lifespan thanks to hardened raceways.
• Uniquely quiet operation with ground raceways.
• Low maintenance.
• Double-row ball bearing version available for high load capacities (Plus)

The Compact Rail consists of three product groups: the T-rail with fixed bearings, the U-rail with compensating bearings, and the K-rail with floating bearings. These can be combined to form self-aligning systems to compensate for misalignment in two planes: axially up to 3.9 mm and radially up to ±2°

• Available in 5 different sizes: 18, 28, 35, 43, 63 mm.
• Possibility to create self-aligning systems ((T+U veya K+U)  to compensate for axial and radial misalignment resulting from mounting surfaces.
• Robust NS carriage made of steel with lateral seals and scrapers. NSD version also available with mounting holes parallel to the main load direction.
• Different anti-corrosion treatments are available for rails and carriage bodies: zinc plating according to ISO 2081 (standard for all rails and carriage bodies), Rollon Alloy, Rollon E-coating, and nickel plating.
• The C-profile, along with its carriages and rotating elements, has compact dimensions.
• Induction-hardened and ground rail surface

Compact Rail Plus linear guides feature new, robust steel carriages with double-row ball bearings for higher load capacities, hard rails with convex raceways, and floating scrapers providing longitudinal protection. Compact Rail Plus is designed for the most demanding applications in terms of load capacity, dynamism, and operating environment. In addition to these features, they retain the self-aligning (misalignment tolerance) capabilities that make this product family unique.

Four versions of carriages are available: the fixed carriage (RV); the floating carriage (RP); the extra floating carriage (RU); and the rotating carriage (RA). The combination of two rails with different carriages makes it possible to create self-aligning systems that can compensate for misalignment occurring in two planes: axial up to 3.5 and radial up to ±1,3°
