Full-Ball Type LM Guide Wide Rail HRW Type

Full-Ball Type LM Guide Wide Rail HRW Type

THK

THK

A structure with a wide rail width and low center of gravity. HSR It is advantageous when there are Mc moment requirements and is thin compared with.

[Features]
· 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.
· Compact heavy load: A high number of effective balls makes it possible to obtain high rigidity in all directions. Has a wide rail width and can adequately withstand moments with a single shaft.
There is a high rigidity in the horizontal direction and there is no need to for reinforcement such as horizontal pressing due to large secondary moments being incurred on the rail cross-section.
· The self-aligning capability achieved from the unique circular arched-groove front face combination (DF set) makes it possible to absorb the mounting error even when there is a preload incurred, and it is also capable of obtaining a smooth linear motion at a high accuracy.
