The Linear Roller Guide RGH15CA, RGH15CAH, and RGH15 is a precision linear guidance solution designed for smooth, repeatable motion along a straight axis. This system combines a hardened steel rail with a matching rollertype carriage to deliver stiffness, low friction, and reliable performance in automation, machining, and robotics applications. The CA and CAH variants are part of the RGH15 family and offer configurations to meet different precision or preload needs while sharing a common base design. Key benefits Precise motion with minimal backlash for repeatable positioning. load carrying capability along the guide axis. Low friction operation enables higher speeds and reduced wear. Sealed, rugged construction helps protect against contaminants and simplifies maintenance. Easy installation and modular compatibility with other components in the RGH series. Key attributes Series and model: Linear Roller Guide, RGH family (RGH15CA, RGH15CAH, RGH15). Functionality: Rollertype carriage and compatible rail provide smooth, rigid linear guidance. Material and finish: Hardened steel components with precisionground raceways and rollers for durability and accuracy. Mounting and integration: Carriage features mounting provisions for straightforward attachment to frames and tooling; designed to work with standard RGH rails and accessories. Performance characteristics: Designed to deliver stable, repeatable motion with low friction and stiffness across operating conditions. Compatibility and installation notes Designed to operate with the RGH15 rail line and the corresponding end blocks and accessories from the RGH family. Suitable for horizontal or vertical axes in automated systems that require precise linear guidance. Typical installation involves mounting the carriage to the moving part and securing the rail to a fixed frame, with alignment checks to ensure performance. Size and configuration 15 series size within the RGH family. Variants include RGH15CA, RGH15CAH, and the base RGH15, offering different configurations to suit precision, preload, or tolerance requirements within the same family.
