THK HSR20SeriesGuide｜four-directional equal loadLinear Rails
THK HSR20 Series是 HSR 标准型Guide Application最广泛 型specification，轨宽 20mm，覆盖 from 1.般automation equipment to 小型CNC machine tools 绝大多数载荷 need 求。凭借four-directional equal load、high rigidity and 优异 互换性，HSR20 视 is Automation工程师 "万能Guide"之选。
1.、HSR20 Series技术概述
HSR20 延续 HSR Series经典 4.列 45° 圆弧沟槽Structure， in 保持Compact outside 形 同时提供了出色 load capacity。 by under 是 HSR20 主要BlockModel and Features：
- HSR20A：标准Flange type，最常用Model，Installation孔 in on 方，组装方便
- HSR20B：加长Flange type，Block更长，额定载荷比 A 型高出approx. 40%
- HSR20C：标准4.方型，Installation孔 from under 方拧入，suitable forCompactInstallation
- HSR20LA： ultra-长Flange type，最高额定载荷Selection，suitable forHeavy load or long service life need 求
2.、关键Performance参数
- 轨宽：20mm | Block宽度：approx. 44mm
- 基本额定动载荷 C：HSR20A approx. 10.2kN | HSR20B approx. 15.6kN | HSR20LA approx. 19.0kN
- 基本额定静载荷 C0：HSR20A approx. 13.8kN | HSR20B approx. 23.1kN | HSR20LA approx. 28.0kN
- Block高度：approx. 30mm
- 精度 etc. 级：N / H / P / SP / UP
3.、 vs HSR15 Comparison
HSR20 相比 HSR15 in load capacity on 有质 飞跃——动载荷approx. is HSR15 1.8-2.2 倍，静载荷approx. is 1.8-2.0 倍，同时轨宽 only 增加 5mm。这 enable 得 HSR20 成 is from 小型升级 to 型Equipment时 Preferred choicesolution。 for 于 need 要 in 有限Space inside 获得更高 can 靠性 and 更long service life Application，HSR20 提供了极具竞争力 Cost-effectiveness。
4.、典型Applicationscenarios
- 数控车床：HSR20A/B 用于 X/Z 轴进给，承受Cutting力
- AutomationAssembly线：HSR20C 4.方型 from under Installation，布局Compact
- Laser切割机：HSR20LA ultra-长型保证光路stable
- PCB Drilling机：high precision P 级配合轻预压确保 micro-孔Positioning
5.、Selection vs 采购
HSR20 Series 标准供货形式 is Guide + Block组合。GuideLength can 按客户 need 求customized切割，精度 etc. 级 and 预压 etc. 级 need in under 单时明确指定。Shenzhen Xianhuihui Technology Co., Ltd.maintains long-term stock of HSR20A/B/C 常用Model In-Stock Inventory， can 提供 1-3 个工作日快速发货 and 免费technical selection support。
