THK

CHIK supplies THK linear guides, linear blocks, linear bearings, linear bushings and ball screws for industrial maintenance, machine building, and production purchasing. We support B2B inquiries from industrial distributors, MRO companies, automation integrators, OEM machine builders and equipment maintenance teams.

THK linear motion components are used in CNC machine tools, industrial robots, semiconductor equipment, packaging machinery, measuring instruments and automated production lines. Buyers can send a complete THK model number, rail and block code, drawing or product photo for availability checking and technical confirmation.

THK Linear Bearings, Guides and Motion Products

Our THK sourcing range covers the following linear motion product categories:

• THK LM guides and linear guide rails for precision positioning and controlled linear movement

• THK linear guide blocks and carriages for machinery maintenance, replacement and equipment production

• THK linear bearings and linear bushings for use with compatible cylindrical linear shafts

• THK ball screws for CNC feed systems, automation equipment and positioning mechanisms

• THK ball splines and cross-roller rings for selected precision motion and rotary applications

THK’s official product system distinguishes LM Guides, linear bushings, ball screws, ball splines and cross-roller rings. These terms should not be treated as interchangeable. The correct product must be identified by its complete model code, dimensions, accuracy requirements and operating conditions.

THK Replacement and Model Identification Support

A complete THK code may include information about the product series, size, block configuration, rail arrangement, preload, accuracy grade, seal type and other technical features. For that reason, purchasing only by a shortened model name may result in an incorrect specification.

When requesting a THK replacement bearing, linear guide block or rail assembly, please provide:

• Complete model number shown on the product or original package

• Rail length and number of blocks per rail

• Required quantity and destination country

• Machine type and application

• Accuracy grade, preload and seal arrangement when known

• Clear photos or drawings if the complete code is unavailable

For discontinued or difficult-to-source models, CHIK can review the available dimensions, installation arrangement and operating requirements to identify possible replacement options. Original-brand sourcing and CHIK OEM alternatives are quoted separately so that buyers can compare availability, technical requirements, delivery schedules and project budgets.

Who We Support

This THK product category is intended for professional buyers, including bearing distributors, industrial wholesalers, machine repair companies, CNC equipment manufacturers, automation system integrators and factory maintenance departments. We support single-model replacement inquiries as well as multi-model purchasing lists for scheduled maintenance and production projects.

THK Linear Bearing Sourcing FAQ

Can CHIK identify a THK model from a photo?

Yes. Send clear photographs of the product marking together with the main dimensions, machine information and required quantity. The information will be reviewed before a quotation or replacement option is proposed.

Can a THK linear block and rail be ordered separately?

This depends on the series, dimensional compatibility, accuracy and preload requirements. Please provide both the rail code and block code so that the required combination can be checked.

Does CHIK offer OEM linear motion alternatives?

Yes. OEM linear bearings, guide blocks and related motion components can be quoted when requested. Original-brand products and CHIK OEM alternatives are identified separately and should not be treated as the same supply option.

Technical note: Product availability, interchangeability and operating suitability must be confirmed according to the complete model code, installation dimensions and application conditions before ordering. THK is a trademark of its respective owner.
