THK LM Guides

THK linear motion systems are unique motion systems in which linear motion is supported by rolling contact elements. These linear motion systems can best be described as a motion system which uses the rotational motion principle of a deep grooved ball bearing. This principle makes it the easiest to use and most economical of all rotational motion bearings.

Since the balls employed as rotating elements are set in raceways having an almost equal radius to the balls that rotate in them, the contact between the balls and the circular arc raceway is changed from conventional point contact to a line contact. This line contact system means that THK LM Guides can handle 13 times the work load and last 2,200 times longer than conventional linear guide ways (round shafts) of the same ball diameter. THK Product News     THK HSR Series Use these guides for a variety of installation directions. The 45-degree contact angle offers 4-way equal load ratings. SIZE: HSR15 | HSR20 | HSR25 | HSR30 | HSR35 | HSR45 | HSR55 | HSR65 THK SR Series Best suited for horizontal guideways, the Type SSR guide features a low-profile, compact design with a 90-degree ball-contact angle. SIZE: SR15 | SR20 | SR25 | SR30 | SR35 | SR45 | SR55 THK HRW Series A wider rail for extra rigidity in all directions. All moment loads are handled by a single rail. SIZE: HRW12LR | HRW14LR | HRW17 | HRW21 | HRW27 | HRW35 | HRW50 THK RSR Series Miniature version of our standard LM Guide. Choose either a 1-block or 2-block per rail configuration. SIZE: RSR7ZM | RSR9ZM | RSR12ZM | RSR15ZM THK RSR-W Series Wider and longer than the standard Type RSR LM block-greater load ratings and permissible moments are possible. Choose either a 1-block or 2-block per rail configuration. SIZE: RSR7W | RSR9W | RSR12W | RSR15W THK GSR Series With its self-adjusting capability, Type GSR is best suited for use where high installation accuracy is difficult to achieve. SIZE: GSR15 | GSR20 | GSR25 | GSR30 | GSR35 THK GSR-R Series Type GSR-R is a modification of Type GSR, with the rack teeth cut on the LM rail. This aids in the design and assembly of drive mechanisms. SIZE: GSR25R | GSR30R | GSR35R
