Product Overview & Features
The LSH series is a premium standard linear guide engineered for high rigidity and precision. It features an advanced four-row circular arc groove structure designed to handle heavy loads with flawless, smooth motion.
-
Equal Load Capacity: The precise 45-degree contact angle design ensures the guide provides equal rated load capacity in all four directions (radial, reverse radial, and lateral), making it highly versatile for various mounting orientations.
-
Self-Aligning Capability: Utilizes a DF (Face-to-Face) configuration that naturally absorbs installation errors and surface inaccuracies. This ensures smooth motion even with slight misalignments.
-
Interchangeability: Thanks to rigorous manufacturing precision, individual blocks and rails of the same accuracy grade are completely interchangeable without compromising performance or preload.
-
Comprehensive Range: Available in a wide array of widths: 15, 20, 25, 30, 35, and 45 mm to suit different load and space requirements.
-
Multiple Configurations: Offers Square (H) and Flanged (F) block types, as well as Standard (N) and Long (L) block lengths to match specific operational strokes.
