Linear Guides

Linear guides are motion systems that pair one or more linear rails with carriages to support loads and provide smooth, low-friction motion along a single axis, or one degree of freedom, using sliding contact or rolling elements. A linear rail is the straight guide track that the carriage travels along, providing the path, support surface, and alignment needed for controlled linear movement. Linear guides from PBC Linear are made in the USA around three core technologies—Gliding Surface Technology, V-Rail Technology, and Cam Roller Technology (CRT)—each optimized for specific application demands while maintaining high rigidity, alignment, and long travel. Gliding Surface Technology uses self-lubricating guides sliding on FrelonGold® liners to eliminate metal-to-metal contact, providing quiet, maintenance-free operation with strong resistance to extreme temperatures, dirt, debris, vibration, and washdown conditions, as used in Mini-Rail® miniature linear rail guides and Uni-Guide™ linear slides. V-Rail Technology uses hardened or stainless steel raceways with self-aligning V-wheels for smooth rolling motion and simplified alignment in systems such as V-Guide™ and IVT (Integral V Technology). Cam Roller Technology (CRT) uses rolling-element carriages on hardened raceways embedded within durable linear rails to support higher loads, longer travel, and higher speeds, as found in Commercial Rail, Redi-Rail®, and heavy-duty Hevi-Rail® systems. Recirculating ball profile rail guides provide high rigidity and load capacity for precision applications. In cantilevered load applications, adherence to the 2:1 binding rule remains an important design consideration, with rolling-element guides generally offering greater tolerance compared to sliding-contact systems.
