Linear Roller Bearings Model Numbers ZARN 1545, ZARN 1747, ZARN 2052, ZARN 2062, ZARN 2557, ZARN 2572 TV Torque Capacity TARN1545, TARN1747, TARN2052, TARN2062, TARN2557, TARN2572 Surface Roughness Ra 0.05 Structure Needle Bearing Key benefits - Supports precise linear motion with high rigidity in a compact design, enabling accurate positioning on small to medium guide systems. - Low friction and wear thanks to a smooth surface finish (Ra 0.05), delivering longer service life and more consistent performance. - Needle bearing structure provides a strong load capacity in a slim form factor, suitable for constrained spaces. - Broad compatibility across multiple model-series (ZARN for sizes and TV variants; TARN for torque-related capacity) to fit a range of applications. 2-3 practical use scenarios - Precision CNC machine tool guides and linear axes where tight tolerances and smooth motion are essential. - Robotic arms, pick-and-place systems, and automation axes that require reliable, high-rigidity linear guidance in limited space. - Printing, packaging, or medical equipment that demands smooth, repeatable linear movement with low wear. Notes - Surface roughness Ra 0.05 and needle bearing construction are designed to optimize performance, longevity, and reliability across the listed model ranges.
