Linear Bearing

An individual block from the THK LM guide HSR series. Extremely useful for sudden design changes and when performing maintenance.

Circulates the ball row using the end plate that is assembled in the LM block when the ball rotates the rotating side with four rows that have been precision ground into the LM block and LM rail.
· The ball will not fall out even if the LM rail is removed because it is held by a holding plate. (Excludes the HSR8,10, and 12).
· Each of the rail rows has been positioned at a 45° contact angle so that the rated load will be the same for all four directions (radial direction, reverse radial direction, horizontal direction) that act on the LM block, which allows it to be used in any position, and is also stable due to incurring a preload with a good balance, and makes it possible to maintain a constant low friction coefficient, and increase rigidity in four directions. Has a low cross-section height, and the LM block has been designed with a high rigidity, which allows for highly precise and consistent linear motion.

Linear bearings are rolling-element and fluid-film devices that reduce friction in motion systems where the motion acts along a straight — or sometimes curved — pathway. They are distinguished from radial bearings in which motion is rotary. Linear bearings are used in machine tool applications such as sliding doors, 3D printers, and automation settings where reducing friction and guiding linear motion is needed. They can be loosely grouped as ball and roller types that use the rolling motion of rolling elements and sliding types that rely on lubricant and low-friction surfaces. Sometimes called linear bushings, linear bearings are manufactured in sintered aluminum bronze, metal/polymer composites, carbon insert styles, polymer-lined sleeves, etc. and rely on a lubricating film to form between the bearing and the shaft while the two are in relative motion.
