Compatible Replacement for HIWIN HGH25CA

This 25mm linear guide block is engineered as a 100% interchangeable alternative to the HIWIN HGH25CA. It matches the original datasheet specifications for dimensions, load ratings (26.48 kN), and stiffness, making it an ideal cost-effective solution for CNC lathes, milling machines, and general automation.

Engineering Data / Performance Specs

Dimensions and load ratings comply with ISO standard series for Size 25.

CNC Linear Guide Rail Set 25mm (High Rigidity) | Fits HGH25CA Series

Dimensional & Mechanical Data
Model Number	HGH25CA (Square Type / Heavy Load)
Nominal Rail Width (W)	25 mm
Basic Dynamic Load Rating (C)	26.48 kN
Basic Static Load Rating (C0)	36.49 kN
Static Moment (MR)	0.63 kN-m
Static Moment (MP / MY)	0.42 kN-m
Mounting Bolt Size	M6 x 20
Weight (Block)	0.59 kg
Weight (Rail)	3.21kg/m

Structure & Features

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 balanced rigidity for multi-axis CNC machines.
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. 5 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 M6 grease nipple.

Installation & Mounting

Surface Prep: Ensure the mounting surface is machined 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 (M6) diagonally (X-pattern) in 2-3 stages.

Accuracy & Preload Class

Accuracy Options:

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

Preload Options:

Z0 (Light): Best for general automation.
ZA (Medium): Recommended for CNC mills/lathes.

Packaging

Included in Box: 1x HGH25CA Linear Block, 1x Grease Nipple (M6).
Protection: Vacuum sealed in anti-rust bag, individually boxed.
