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.
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.
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.
