Linear Motion Guides for Rail

THK became the first company in the world to develop and commercialize the Linear Motion (LM) Guide in 1972. Linear motion systems enabled rapid improvements in the accuracy, speed and labour-saving potential of advanced mechatronic instruments. Today THK is the world’s No.1 market leader of linear motion guides.

THK products such as linear guides, actuators, ball screws, link balls and cross roller rings are in use as essential mechanical components in all industries. Due to accumulated expertise in quality control, developing technology and proven reliability, THK products have enormous potential in the development of applications for the railway industry.

Examples of Applications in the Railway Industry

Flexible seat layouts: The combination of linear guides, recirculating ball screws and maintenance-free aluminium bearing allows easy automated change of the seat layout.

Seat reclining: Utility Slides offer reliable and cost-conscious performance for seat reclining.

Movable tables: Single Rail LM Guides provide a high moment load and can be combined with TN clamper.

Sliders and actuators for train doors: THK’s Utility Sliders offer high reliability in dusty condition and adjustability of miss-alignment for maintenance free and reliable performance.

R Guide for tilting train bogies: R Guides allow circular motion of 5m and longer, which is impossible with swivel bearings and are ideal solution for the tilting motion of pendulum trains.

Platform doors: Caged Ball LM Guides and Cam Followers are used in the platform doors that protect people from accidentally falling onto the railroad tracks. THK’s products, with their high durability and quiet operation, hold these overhung platform doors securely.

Engineering Service Provider

THK’s strength lies not merely in offering standardized components, but also in flexible development and proposals for customized products. In addition to improving development speed to expand applications in the railway industry, we are promoting the development of railway products with an eye toward five and ten years down the road.
