Structure & Features

CNC Linear Guide Rail Set 15mm (High Rigidity) | Fits HGH15CA Series

  • 4-Row Circular Arc Design: Features a 45° contact angle design that ensures equal load capacity in all four directions (radial, reverse radial, and lateral). This provides superior stability for compact X/Y axis builds.
  • Material Standard: Block body and balls are manufactured using GCr15 Bearing Steel, hardened to HRC 60-62 for wear resistance.

Lubrication Guide

⚠️ Critical: Blocks are shipped with anti-rust oil, NOT lubricant. You must grease them before use.

  • Grease Type: Lithium Soap-based Grease (NLGI No.2).
  • Initial Fill Amount: Approx. 1 cm³ per block (Fill slowly until grease overflows slightly).
  • Refill Interval: Every 100km of travel distance, or every 3-6 months depending on operating speed.
  • Method: Inject via the supplied M4 grease nipple.

Installation & Mounting

  • Surface Prep: Ensure the mounting surface is flat. Rough surfaces will reduce accuracy and lifespan.
  • Datum Plane: Press the block reference edge firmly against the mounting shoulder before tightening.
  • Torque Sequence: Tighten the 4 bolts (M4) diagonally (X-pattern) in 2-3 stages. Do not fully tighten one bolt at a time.

Accuracy & Preload Class

Accuracy Options:
  • C (Normal): +/- 0.1mm (Standard Stock)
  • H (High): +/- 0.03mm (Recommended for Precision)
Preload Options:
  • Z0 (Light): Best for 3D printers & light automation.
  • ZA (Medium): Recommended for small CNC routers.

Packaging

Included in Box: 1x HGH15CA Linear Block, 1x Grease Nipple (M4).
Protection: Vacuum sealed in anti-rust bag, individually boxed.
