[Individual Block Units] Full-Ball Type LM Guide, International Standard, HSR Type

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

[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.
· 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.

Frequently asked question (FAQ)

Question: What is a Full-Ball Type LM Guide HSR?: Answer: The Full-Ball Type LM Guide HSR is a precision linear motion guide that uses a circulating ball system for smooth and stable movement. It is designed to provide high rigidity, accuracy, and consistent low-friction performance.
Question: What are the benefits of using an HSR-type LM guide?: Answer: •High load-bearing capacity
•Smooth and precise linear motion
•Long lifespan due to high-quality materials
•Stable operation under varying load conditions
Question: How does the 45° contact angle improve LM guide performance?: Answer: The 45° contact angle ensures equal load distribution in all four directions (radial, reverse radial, and horizontal), enhancing stability, reducing friction, and maintaining consistent motion accuracy.
Question: Can I replace only the LM block instead of the entire LM guide?: Answer: Yes, the HSR-type LM guide allows for individual block replacement, making it ideal for maintenance and design modifications without changing the entire rail system.
