AirTAC LSH Series Self-Lubricating Linear Guide – High-Rigidity Precision Linear Rail
The AirTAC LSH Series Self-Lubricator Standard Linear Guide is a precision ball-type linear guide with an integrated self-lubrication unit, designed to reduce grease maintenance and extend operating life. Available in 15, 20, 25, 30, 35 and 45 mm sizes, it supports square or flange blocks, standard or long block types, multiple preload levels, N/H/P accuracy grades, and single or butt-jointed rails. Its high-capacity lubricant reservoir and built-in dust protection make it ideal for CNC machines, robotics, industrial automation and hard-to-access lubrication points.

Specification
AirTAC LSH Series Self-Lubricator Standard Linear Guide
The AirTAC LSH Series Self-Lubricator Standard Linear Guide is a ball-type linear guide with an integrated self-lubrication system. It continuously supplies lubricant to the ball raceways, making it suitable for continuous-duty machinery, restricted spaces and applications where regular grease maintenance is difficult.
Features
- Integrated self-lubricator reduces routine grease maintenance.
- High-capacity lubricant reservoir supports application-specific lubricants.
- Built-in dust protection helps protect the steel balls and raceways.
- The self-lubrication unit can be installed or removed conveniently.
- Square and flange block styles support different machine structures.
- Single and butt-jointed rails are available for short- or long-travel systems.
- The suffix E identifies the Self-Lubricator version.
Main Specifications
- Series sizes: LSH15, LSH20, LSH25, LSH30, LSH35 and LSH45.
- Rail widths: 15 mm, 20 mm, 23 mm, 28 mm, 34 mm and 45 mm.
- Block styles:
- H: square block.
- F1: flange block, top mounting.
- F2: flange block, bottom mounting.
- F3: flange block, top or bottom mounting.
- Block length: N – standard, L – long; long block is not available for LSH15.
- Number of blocks: one or two blocks per rail.
- Preload: A – standard clearance, B – light, C – medium, D – heavy.
- Accuracy grades: N – normal, H – high, P – precision.
- Surface finish: natural metal or BB black chrome coating.
- Rail mounting: top mount or bottom mount.
Advantages
- Reduces lubrication labor and maintenance costs.
- Helps prevent insufficient lubrication in hard-to-access positions.
- Provides smooth motion, low friction and high rigidity.
- Wide selection of sizes, block styles and preload levels.
- Suitable for long-running machinery and production lines with limited maintenance access.
Note: the self-lubricating block is not recommended for ultra-smooth applications because lubricant viscosity may increase running resistance by approximately 5–7 N.
Applications
- CNC machines and precision machine tools.
- Industrial robots and pick-and-place systems.
- Automated assembly and packaging equipment.
- Electronics and semiconductor manufacturing machines.
- Precision linear tables and positioning systems.
- Measuring, inspection and machine-vision equipment.
- Industrial automation lines requiring reduced maintenance.
