About HIWIN
HIWIN Technologies Corp., headquartered in Taichung, Taiwan, is one of the world's largest dedicated linear motion manufacturers with a truly comprehensive product portfolio. From miniature ball guides to heavy-duty roller guides, from precision-ground ball screws to integrated linear motor stages, HIWIN offers a one-stop solution for machine builders seeking a single-brand supply chain.
HIWIN's competitive advantage lies in its combination of Japanese-grade quality control with Taiwanese manufacturing agility — delivering consistent C3/C5 accuracy across high-volume production runs while maintaining 2-4 week lead times on standard catalog items. This has made HIWIN the dominant brand in China's 3C electronics, lithium battery, and photovoltaic equipment manufacturing ecosystems.
Core Product Lines
HG / EG / QE / QH / WE / MG
Ball & Roller Linear Guides
Full family from miniature (MG 5 mm) to heavy roller (QH 65 mm). HG series is the industry-standard interchange for general automation. QH roller series for high-rigidity applications.
Applications: 3C automation, CNC machines, packaging, medical, photovoltaic
Super S / Super T / R1 / RD / OFI
Precision Ball Screws
Ground (Super S/T, C3/C5) and rolled (R1, C7) ball screws with single and double nut configurations. Optional cooling channel (OFI) for thermal stability.
Applications: Machine tool axes, electronic assembly, injection molding, robotics
KK / KA / KS
Linear Actuator Modules
Compact single-axis modules integrating HIWIN guide and ball screw. KK series is the most popular for general automation with aluminum base and top/bottom mounting options.
Applications: Pick & place, dispensing, inspection, lab automation
Torque Motor / Linear Motor / Direct Drive
Rotary & Linear Motors
Frameless torque motors for rotary tables, iron-core and ironless linear motors for high-dynamics axes, and DDR direct-drive rotary motors.

Key Applications & Operating Conditions
Lithium Battery Manufacturing
Long-stroke C5 HG guides with anti-corrosion coatings for electrode coating, slitting, and cell stacking machines. HIWIN's volume manufacturing capacity ensures stable delivery for gigafactory-scale projects.
Photovoltaic Cell Production
HG/EG series guides for solar cell stringers, laminators, and module framing lines. High-temperature variants (up to 120°C with special seals) for soldering and lamination stations.
CNC Machine Tools (Mid-Range)
QH roller guides and Super T C3 ball screws for 3-axis and 5-axis vertical machining centers. Proven performance in Taiwanese and Chinese machine tool builder specifications.
Cross-Brand Compatibility Reference
HIWIN HG series is the most common cross-reference target for THK HSR/SSR in standard automation applications — 80%+ dimensional compatibility in guide rail width, bolt pitch, and block height for sizes 15-45. HIWIN and PMI are frequently cross-shopped in cost-sensitive CNC builds; HIWIN typically offers wider availability and faster delivery. For ultra-precision applications (C0-C1), HIWIN does not directly compete with THK or Schneeberger.
Common Faults & Maintenance
- HG series guide noise after high-mileage service: Clean and re-lubricate with HIWIN G-80 lithium grease (NLGI 2). Check the end seal condition — hardened or worn seals allow contamination ingress. Replace seals as a set if hardness exceeds Shore A 85.
- Ball screw backlash increase over time: HIWIN double-nut ball screws use a spacer ring to set preload. If backlash exceeds 0.01 mm, a thicker spacer may restore preload — but this requires factory rework. For field repair, replace the ball screw assembly and verify the replacement has the same preload class.
- KK module positioning repeatability degradation: Check the coupling between the motor shaft and ball screw journal. A loose coupling set screw is the most common cause of positioning drift. Verify the module mounting to the machine bed — base flexure under load will degrade repeatability.
Frequently Asked Questions
Q1: How does HIWIN HG compare to THK HSR in terms of quality and price?
HIWIN HG and THK HSR share the same four-row ball circulation design and dimensional standards (ISO 12090-1). HIWIN typically offers 20-40% cost savings versus THK while maintaining C3/C5 accuracy. The trade-off: THK generally has a 20-30% longer fatigue life rating (L10) under identical load conditions due to proprietary raceway surface finishing.
Q2: What is the most popular HIWIN guide series for general automation?
The HG series is HIWIN's flagship product and the most widely used linear guide globally in automation. Sizes HG15-HG35 cover the vast majority of applications from small pick-and-place units to mid-sized gantry robots. EG series (lower profile) is preferred when height is constrained, and QH roller series for heavy cutting.
Q3: Does HIWIN offer stainless steel linear guides for cleanroom use?
Yes. HIWIN offers the MG series in full stainless steel (guide rail, carriage, and balls) for cleanroom and vacuum applications. The CG series provides a more cost-effective hybrid solution with stainless carriage and chromed rail. Contact thk@591888888.com for cleanroom-grade specifications.
Q4: What is the typical MOQ for HIWIN products?
HIWIN does not enforce strict minimum order quantities through Xianhuihui Technology. Single-unit prototype orders are accepted. For custom-length ball screws and special preload configurations, a minimum 10-unit order may apply. Standard catalog items ship in 1-2 weeks.
