The Linear Roller Guide RGH20CA, RGH20CAH, RGH20 is a precise linear motion solution designed for demanding automation, machine tools and robotic systems. It provides smooth, stable guidance with strong load handling, contributing to accurate positioning and reliable operation in a compact form. Key benefits rigidity and stable guidance: precisionground rails and roller elements deliver consistent stiffness, minimizing deflection under load for repeatable positioning. Smooth, lowfriction motion: optimized roller guidance reduces friction and wear, enabling faster travel with quieter operation. Durable, long service life: hardened steel components and robust roller bearings are built for repeated cycles in industrial environments. Flexible installation and maintenance: modular RGH20 components allow straightforward assembly, disassembly and component replacement as needed. Variant availability for different needs: the family includes RGH20CA, RGH20CAH and RGH20 options to accommodate lubrication, sealing and mounting preferences. Key attributes Functionality: linear roller guide providing precise linear motion with a carriage riding on a hardened rail, suitable for accuracy positioning and repeatable motion. Compatibility: part of the RGH20 family, including RGH20CA, RGH20CAH and RGH20 variants, designed to fit standard RGH20 rails and mounting interfaces. Size: designed for the 20series RGH profile, offering a compact footprint suitable for tight automation layouts. Material: strength steel components for rails and rollers, engineered for rigidity and long life in industrial settings. Performance: engineered for reliable, smooth travel with stable load support across multiple axes, supporting precise alignment and repeatable operations in repetitivemotion applications. Use cases and applications CNC and milling machine axes: X, Y or Z axis guidance requiring precise, repeatable motion with rigidity to maintain cutting accuracy. Automated packaging and inspection lines: linear guidance for gantry or carriage systems that move parts or sensors with consistent positioning. 3D printing and additive manufacturing equipment: motion guidance for printer beds or extruder carriages where stable, smooth travel improves print quality and repeatability. Notes on use and maintenance Ensure proper mounting alignment and secure fixation to avoid axial and lateral play. Use appropriate lubrication and seals per the chosen variant (such as CA or CAH) to match operating environment and maintenance schedule. Inspect rollers and raceways for wear or contaminants, and service or components as needed to maintain performance. This description reflects the product family RGH20CA, RGH20CAH and RGH20, emphasizing their common functionality, compatibility and use in precision linear motion applications without introducing unrelated details.
