LSQH Series Quiet Self-Lubricating Linear Guide
Built-in Lubrication Reservoir | Maintenance Free | Low Noise
Product Features & Self-Lubricating Structure
The LSQH series represents a technological advancement in linear motion, featuring a built-in, high-capacity oil tank structure (designated by Code E). This design provides exceptional long-term, maintenance-free operation while significantly reducing running noise.
- Maintenance Free: Engineered for long-term continuous use in normal industrial environments without the need for manual grease replenishment or extra maintenance.
- Cost & Space Saving: Completely eliminates the need for expensive external forced-lubrication piping or automatic lubrication systems, saving both cost and installation space.
- Clean Environment: The optimized capillary oil application system delivers precise lubrication directly to the raceways, drastically reducing oil leakage and preventing environmental contamination.
- Quiet Operation: Features an optimized ball circulation path and resin return tubes that significantly dampen the collision noise of steel balls, resulting in smooth and quiet motion.
- Dust Proof Protection: Comes standard with built-in end seals and scrapers to effectively keep dust out and lock lubrication in.
- Complete Interchangeability: The mounting dimensions are 100% compatible and interchangeable with the standard LSH series. The integrated self-lube block allows for easy mounting and dismounting without losing components.

Example: LSQH 20 H N 1 X 2970 T 2940 ...
Individual Component Ordering
1. Block Only Ordering (BK)
Example: LSQH 20 BK - H N - H - D - AM8 - E
| Item | Options & Description |
|---|---|
| Model Code | LSQH: Quiet Series |
| Width | 15, 20, 25, 30, 35 |
| Component | BK: Block Only |
| Type | H: Square | F1/F2/F3: Flange |
| Spec | N: Standard | L: Long |

2. Rail Only Ordering (RL)
Important: LSQH series blocks use the standard LSH Series Rails. When ordering the rail separately, you must use the LSH model code.
Example: LSH 15 RL X 4000 - H - D - T
| Item | Options & Description |
|---|---|
| Model Code | LSH + Width + RL (Rail Only) |
| Joint / Length | X: Jointed | Blank: Single. Followed by Length in mm. |
| Accuracy | N, H, P |
| Assembly Code | D, E... (Must match block Preload code) |
| Mounting | Blank: Upper Locking | T: Lower Locking |
