In the realm of precision automation, where space is at a premium and performance is non-negotiable, the Small Size Low Series Flange Type Linear Guide Unit stands as an essential component for modern machinery. Designed for applications demanding high accuracy within a constrained footprint, this linear guide block is engineered to deliver exceptional stability and smooth motion. Its integrated flange design simplifies installation and provides superior mounting rigidity, making it a versatile choice for a wide range of industrial settings. For engineers seeking the pinnacle of exactitude, our High Precision Low Series Flange Linear Motion Block variant offers enhanced geometric accuracy and running parallelism. When a unified, robust assembly is required, the Integrated Flange Low Series Linear Rail Guide Block provides a seamless solution that increases overall system stiffness. For general Industrial Low Series Flange Type Linear Rail Block applications, this unit offers reliable, maintenance-free operation. In scenarios involving substantial forces, the design principles extend to our Heavy Load Low Series Flange Type Linear Rail Block, ensuring durability and long service life under demanding conditions.


The core advantage of the Small Size Low Series Flange Type Linear Guide Unit lies in its meticulously optimized design parameters. By maintaining a low profile, it achieves significant space savings without compromising on load capacity or precision. The flange-type structure offers multiple mounting options, granting designers greater flexibility in machine layout. Key performance metrics for a standard model are detailed below, illustrating the engineering excellence embedded in this compact guide.

  • Compact Design: A reduced height profile allows for integration into slim equipment designs.
  • High Rigidity: The flange construction and optimized ball circuit ensure minimal deformation under load.
  • Smooth Operation: Precision-ground raceways and high-grade balls result in low friction and consistent movement.
  • Easy Installation: Pre-drilled mounting holes on the flange simplify alignment and secure fixing.
  • Sealed Construction: Integrated seals effectively prevent contamination from dust and debris, enhancing reliability.
  • Interchangeability: Designed to be compatible with standard low-series linear rails for easy system assembly.

This detailed specification table allows for precise selection based on the specific force, moment, and spatial requirements of your application. The Small Size Low Series Flange Type Linear Guide Unit is manufactured from high-carbon chromium bearing steel, which undergoes heat treatment to achieve the necessary hardness and wear resistance. Each unit is pre-loaded to eliminate internal clearance, ensuring high positional accuracy and negating backlash during operation. The incorporation of a lubricating grease nipple facilitates easy maintenance, allowing for periodic re-lubrication to sustain optimal performance over extended periods. Its application spans across critical sectors including semiconductor manufacturing equipment, precision inspection instruments, medical devices, and compact robotic modules where reliable linear motion in a minimal space is paramount.
