Product name: Linear Guide Rail Model: HGR15 What this product does Provides accurate, low-friction linear motion for machinery and equipment. Designed to guide and support linear carriages in precise, repeatable travel along a fixed path. Key specifications (exact) Model: HGR15 Rail height: 15 mm Rail width: 15 mm Fixed screw size: M4 × 16 mm Available lengths: 100 mm, 150 mm, 200 mm, 250 mm, 300 mm, 350 mm, 400 mm, 450 mm, 500 mm, 550 mm, 600 mm, 650 mm, 700 mm, 750 mm, 800 mm, 850 mm, 900 mm, 950 mm, 1000 mm, 1050 mm, 1100 mm Why customers choose this rail Precision movement: Engineered to support smooth, accurate linear travel, reducing play and improving positional repeatability. Easy mounting: Standard M4×16 fixing screw size and compact 15×15 mm profile simplify installation in tight or compact assemblies. Versatile lengths: Wide range of available lengths lets you select the exact rail size you need without excess trimming or modification. Reliable support for linear blocks: Designed as part of the HGR15 line to work with compatible HGR15 carriages and components for consistent system performance. Performance and compatibility notes Function: Linear guidance for stages, sliders, and other moving elements requiring precise straight-line motion. Size: Compact 15 mm height and 15 mm width profile fits constrained spaces while still providing stable support. Mounting: Uses M4×16 fixing screws for secure attachment; ensure matching carriage/block type for optimal compatibility. Durability: Built for repeated motion applications; follow recommended lubrication and mounting practices to maximize service life. Practical applications (use scenarios) CNC machines and milling tables: Use HGR15 rails to guide tool heads or workholding stages when compact, accurate travel is required. Automation and pick-and-place equipment: Provide repeatable linear motion for actuators and transfer stages in assembly lines. Precision hobby and prototyping machines: Ideal for compact 3D printers, laser cutters, and inspection stages where space is limited but accuracy matters. Installation tips Select the correct rail length from the available sizes before ordering to avoid unnecessary cuts or modifications. Use M4×16 mounting screws and follow torque recommendations for your equipment to ensure secure fastening without deforming the rail. Pair the rail with compatible HGR15 carriages/blocks and observe manufacturer lubrication intervals for best performance.
