Description
Thomson RoundRail 1" Dia x 45" Linear Guide Rod Stainless Steel w/ Aluminum Bearing Block
This is a Thomson-RL RoundRail stainless steel linear guide rod measuring 1 inch in diameter and 45 inches (3 ft 9 in) long, paired with an aluminum mounting block housing a Diamond Case SU16 linear bearing. Thomson's RoundRail system is a classic and widely used approach to linear motion guidance, where a precision-ground round shaft serves as both the guide rail and the load-bearing surface, with the carriage or bearing block riding directly along the rod.

Applications
Thomson RoundRail linear guide rods are a standard component in linear motion systems used across industrial automation, CNC machinery, robotics, packaging equipment, semiconductor handling, and laboratory automation. The round-rail format has been a Thomson staple for decades — it pairs with pillow blocks, open bearing blocks, or end-support brackets to form complete linear slide assemblies. The 1-inch diameter shaft is a common size suited to moderate load and span applications. The Diamond Case SU16 bearing inside the aluminum block is a Thomson-proprietary bearing design featuring a hardened case for extended wear life on ground steel or stainless shafting. These assemblies are commonly found in existing linear slide tables, gantry stages, and actuator systems and can serve as replacement or spare components in those setups.
This Thomson RoundRail stainless steel linear guide rod and aluminum bearing block assembly has been inspected and appears to be in good used condition. The rod surface shows light surface marks consistent with prior use but is straight and intact with no visible bends or damage. The aluminum bearing block shows some grease/lubricant residue around the SU16 bearing bore, which is normal for a used linear motion component. The threaded end of the rod is present and intact. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
