The THK Technical Support Site

The THK Technical Support Site is a web service for registered members that provides abundant content ranging from catalogs to CAD data, product FAQs, and technical documents. It is equipped with tools to help people involved in designing machinery and robots choose the optimal model number and calculate service life.

THK Catalog Center

You can view and download the latest catalogs and instruction manuals. It also allows you to browse by product category or search by model number or product name. Nine languages are supported, including English, Japanese, Chinese (Simplified and Traditional), and German.

Technical FAQ

You can view over 400 questions and answers related to engineering, design, troubleshooting, and more. They are organized by product group, or you can search the FAQ.

Q, Is it possible to purchase only the LM block or LM rail?

A, Yes. Normally, the LM block and LM rail are a set delivered after movement adjustment/verification is complete. Thus, when purchasing only an LM block, please send the LM Guide set (LM block + LM rail) or LM rail to be used with the LM block you would like to purchase. After adjusting the movement with your existing LM Guide set or LM rail, we will deliver the new LM block with the items you sent us. We understand that it may not be possible to send the LM Guide set or LM rail to be used with the new LM block. However, in such cases we still can respond. Please contact THK.

Q, What should be kept in mind when choosing a ball screw?

A. When choosing a ball screw, select a model you might consider using and determine the critical speed and DN value from the number of revolutions, depending on the usage conditions. Then, calculate the service life to determine if the requirement was met. Remember to also consider the service life of the bearings that support the ball screw. Change the shaft diameter according to the results.

THK Technical Materials

These materials include basic data and selection guidelines for each product, useful information about maintenance, and other contents that can’t be covered in detail in the catalog.

THK Technical Support: Services for Engineers

Optimal Product Selection Tool

Two functions are available: “Find by Conditions” for when you know the weight and speed for your application, and “Find by Dimensions” for when you are planning to replace an existing LM Guide. You can use it for new purchases or repeat orders. It will reduce the total lead time of your equipment design.

Detailed Life Calculator

This service calculates product life specific to each customer’s applications (e.g. eccentric loads). It includes a broad lineup of LM Guide, ball screw, and electric actuator products.

CAD Data

You can download 2D and 3D CAD data in a variety of CAD formats, including DWG and STEP, to help you in your next equipment design project.
