Compatible Replacement for HIWIN HGH20HA

This 20mm linear guide block is the Long Type (Super Heavy Load) version, engineered as a 100% interchangeable alternative to the HIWIN HGH20HA. It features a longer body for increased load capacity (21.18 kN) and higher rigidity, making it ideal for CNC Z-axis and vertical automation applications.

Engineering Data / Performance Specs

Dimensions and load ratings comply with ISO standard series for Size 20 (Long).

CNC Linear Guide Rail Set 20mm (High Rigidity) | Fits HGH20HA Series

Dimensional & Mechanical Data
Model Number	HGH20HA (Square Type / Super Heavy Load)
Nominal Rail Width (W)	20 mm
Basic Dynamic Load Rating (C)	21.18 kN
Basic Static Load Rating (C0)	35.90 kN
Static Moment (MR)	0.48 kN-m
Static Moment (MP / MY)	0.37 kN-m
Mounting Bolt Size	M5 x 16

Structure & Features

High Rigidity Long Block: The "HA" series features more bearing balls than standard blocks, providing 30% higher load capacity and stiffness.
4-Row Circular Arc Design: Features a 45° contact angle design that ensures equal load capacity in all four directions.
Material Standard: Manufactured using GCr15 Bearing Steel, hardened to HRC 60-62.

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. 3 cm³ per block (Fill slowly until grease overflows slightly).
Refill Interval: Every 100km of travel distance, or every 3-6 months.
Method: Inject via the supplied M5 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 (M5) diagonally (X-pattern) in 2-3 stages.

Accuracy & Preload Class

Accuracy Options:

C (Normal): +/- 0.1mm (Standard Stock)
H (High): +/- 0.03mm (Recommended)

Preload Options:

Z0 (Light): Smooth motion, low vibration.
ZA (Medium): Increased rigidity for CNC Z-Axis.

Packaging

Included in Box: 1x HGH20HA Linear Block, 1x Grease Nipple (M5).
Protection: Vacuum sealed in anti-rust bag, individually boxed.
