[Single block] Full-ball type LM guide, world standard HSR model (Part Numbers)

Volume Discount

This is a single block from the THK LM guide HSR series. Very convenient for sudden design changes or maintenance.

[Features]
· The balls roll along four rows of precisely ground raceways on the LM rail and LM block, and the end plate built into the LM block circulates the rows of balls.
· Even if the LM rail is removed, the balls are retained by the retaining plate and will not fall out (except for HSR8, 10, and 12 types).
· Each ball row is arranged at a contact angle of 45° so that the LM block has the same rated load in all four directions (radial, reverse radial, and lateral directions), making it suitable for use in any orientation. In addition, a well-balanced preload can be applied, allowing you to increase rigidity in all four directions while maintaining a consistently low coefficient of friction. With a low cross section height and a LM block designed for high stiffness, you can achieve highly accurate and stable 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.
