1. THK Linear Guide Block Product Overview

THK Linear guidesblock由Precisionprecision-groundguideand built-inrolling element的blockcomposed of，Throughrolling elementbetween the rail surface andblockgrooves via recirculating rolling to achieve low-friction、High Accuracylinear motion.。THK Offering Complete product range，covering miniature guides（SRS/RSR Series）、Standard型（HSR/SHS/SSR Series）、Wide-Rail Guides（SHW Series）、Roller Guides（SRG Series）、Arc Guides（HCR Series）and other types，meeting diverse operating requirements from semiconductor precision positioning to heavy-duty machine tool loads.。

2. Core Product Series & Technical Features

1. HSR Series —— Four-Directional Equal-Load Standard Guide

HSR Seriesis THK's most classic standard linear guide, featuring a four-row circular arc groove structure with four-directional equal-load capability.45° The 45-degree contact angle design enables it in radial,、reverse-radial and lateral directions.，Especially suitable forInstallation面存在Machining误差或需要承受复合方向载荷的场合。HSR SeriesOffering 从 15 到 85 MultipleSpecifications，covering selection needs from small to large equipment.。

2. SHS Series —— High-Load Low-Noise Guide

SHS Series在 HSR Based onOptimization了rolling elementrecirculation path，adopts a ball retainer design，effectively eliminates metal-to-metal collision between balls，significantly reduces operating noise（同Specifications比 HSR lower by approximately 2-4 dB）。simultaneously，The ball retainer ensures more uniform grease distribution，extends maintenance intervals，is ideal for medium to largeAutomated production linesand cleanroom environments.。

3. SRG Series —— Roller Guides

SRG Seriesuses cylindrical rollers instead of steel ballsAs a rolling element，contact mode changed from point contact to line contact.，rigidity approximately 2-3 倍，rated loads substantially increased.。SRG Seriesparticularly suitable for injection molding machines,、stamping presses、large machining centers, and other heavy-duty equipment requiring ultra-high rigidity and impact resistance.。

4. SRS/RSR Microguide

For space-constrained yet high-precision applications such as semiconductor packaging equipment, precision measuring instruments, and medical testing devices, SRS Series（standard micro）和 RSR Series（ultra-thin micro）Offering rail width 7mm micro-sized solutions starting from，achieving sub-micron positioning accuracy.。

3. Typical Application Scenarios
