LSD Series Linear Guide
Product Features
- Low Profile Design: The LSD series features a reduced combined height of the block and rail. It is highly suitable for industrial machinery and automation equipment where installation space is strictly limited.
- High Load Capacity: The optimized raceway geometry allows for a 4-way equal load rating design. It can bear high loads uniformly in radial, reverse radial, and lateral directions.
- Smooth & Stable Movement: Precision-machined ball circulation paths and retainers ensure low friction, smooth movement, and high running accuracy even at high speeds.
- Interchangeability: Strict dimensional control during manufacturing ensures that blocks and rails can be freely interchanged within the same accuracy class without compromising performance.
- Comprehensive Dust Protection: Equipped with standard end seals. Options for double seals (DD) and metal scrapers (ZZ) are available to prevent dust and debris ingress in harsh working environments.

| 10 | Joint Mark 2 | T: Joint mark for the second connection (if applicable). |
| 11 | 3rd Rail Length | Length of the third rail segment (e.g., 3920). |
