  • Features a 4-row circular arc design with a 45° contact angle for equal load capacity in all four directions.
  • Constructed from GCr15 Bearing Steel hardened to HRC 60-62 for exceptional wear resistance.
  • Offers basic dynamic load rating of 49.52 kN and static load rating of 69.16 kN for heavy-duty applications.
  • Available in multiple accuracy classes including Normal (C) and High (H) precision options.
  • Includes preload options Z0 (Light) for general automation and ZA (Medium) for heavy CNC mills.
  • Comes with grease nipple for lubrication and requires lithium soap-based grease (NLGI No.2) for operation.
  • Packaged vacuum-sealed in anti-rust bag with individual boxing for optimal protection during shipping.
Faqs:
  • Is this linear guide block compatible with HIWIN HGH35CA systems?
    Yes, this 35mm linear guide block is engineered as a 100% interchangeable alternative to the HIWIN HGH35CA, matching all original datasheet specifications for dimensions, load ratings, and mass.
  • What lubrication is required for this linear guide block?
    The blocks are shipped with anti-rust oil only and must be greased before use. Use lithium soap-based grease (NLGI No.2) with an initial fill of approximately 10 cm³ per block, and refill every 100km of travel or 3-6 months depending on operating speed.
  • What are the available accuracy and preload options for this guide block?
    Accuracy options include C (Normal) at +/- 0.1mm and H (High) at +/- 0.03mm. Preload options include Z0 (Light) for general automation and ZA (Medium) recommended for heavy CNC milling applications.
  • What is the recommended installation procedure for this linear guide block?
    Ensure the mounting surface is machined flat, press the block reference edge firmly against the mounting shoulder, and tighten the four M8 bolts diagonally in an X-pattern across 2-3 stages for proper installation.
