Why DTX-LG linear Block?

01. 高强度材料

直线运动部件

DTX-LG直线导轨与滑块采用优质钢材制造,并经过先进的热处理工艺,表面硬度达到59–62 HRC。这确保了卓越的耐磨性、更高的负载能力,即使在重载工况下也能延长使用寿命。

每个精密法兰直线滑块均配备硬化至61–66 HRC的优质钢球。卓越的硬度提供了出色的滚动性能,改善了负载分布,并保证了平稳、精确的直线运动,同时摩擦极小。

02. 台湾设计,中国制造

Each linear rail and blocks corrosion resistant carriage is manufactured in-house with CNC drilling and grinding to ensure accuracy and consistency. With 16 production lines and an annual output of 3,600,000 pieces, DTX-LG guarantees strict quality control, large-scale supply, and reliable delivery worldwide.

03. 先进的自润滑系统

自润滑系统

端盖中集成了内置润滑机构,该机构由一个储油单元和一个释油单元组成。内部的导油元件不仅能吸收和储存润滑油,还能通过其特殊结构将润滑油逐渐释放到滚道中。此设计确保持续润滑,显著减少维护需求,并保证滑块长期可靠运行。是数控机床的理想法兰直线滑块。

04. 装配前确保清洁度与可靠性

Each heavy load linear guide undergoes a thorough ultrasonic cleaning process to remove machining residues, fine metal particles, and surface impurities. This is followed by hot air drying to eliminate moisture and prevent corrosion. Only after these cleaning and drying steps are completed does the block proceed to the assembly stage, ensuring that every linear motion components maintains a clean, contaminant-free surface for smooth motion and long-term reliability.

05. 全周期ISO质量管理体系

DTX-LG已获得多项ISO认证,并在生产的每个阶段全面实施标准化的ISO质量保证管理流程。从原材料检验、机加工到装配和最终测试,每一步都严格遵循ISO指南。这确保了产品的一致性、可追溯性并符合国际质量标准,巩固了我们提供可靠且全球认可的直线导轨与滑块组件的承诺。

DTX-LG SG series linear guide assembly are fully interchangeable with the Hiwin HG series linear guideway, as well as other major brands such as THK, TBI, and IKO. Three types of carriages are available — flange type, square type, and the L-type carriage, which has the same assembly height as the flange type, greatly reducing space constraints. The DTX-LG assembly offers travel accuracy up to 2 microns, making it ideal for heavy load linear guide applications and other heavy duty linear track system requirements.

To simplify ordering, you can simply send us the brand and model you wish to replace, and our engineers will recommend the corresponding DTX-LG model. Alternatively, you may send us your required assembly line guide drawings directly for quick matching.

As one of the leading linear guideways manufacturers, DTX-LG not only provides customized lengths, mounting hole patterns, anti-corrosion treatments, and engineering support for end-users, but also comprehensive services for linear guide distributor partners. These include customized packaging, dedicated training, joint marketing campaigns, lead conversion support, and consignment stock programs — where we store a certain quantity of standard heavy duty linear rail products in the distributor’s warehouse, allowing settlement after sales to reduce financial pressure.
