1. Introduction
The PMI MSR series linear guideway is a full roller type system designed for applications requiring high rigidity, heavy load capacity, and high accuracy. Unlike traditional ball-type guideways, the MSR series utilizes rollers, which significantly enhance its load-bearing capabilities and overall stiffness.
This linear guideway is engineered for precise motion control, offering high positioning accuracy and repeatability. Its design minimizes the difference between dynamic and static friction, effectively preventing stick-slip phenomena during submicron feeding operations.
Key features include:
- High Rigidity and Loading: Utilizes rollers for superior rigidity and load capacity compared to ball-type systems of the same size.
- High Positioning Accuracy: Low friction coefficient ensures precise movement and minimal stick-slip.
- Low Frictional Resistance: Only 1/20th to 1/40th of that in a slide guide, leading to reduced power consumption and less temperature rise during high-speed operation.
- Four-Way Load Design: Optimized mechanical design allows the guideway to bear loads in all four directions (radial, reversed radial, and both lateral directions).
- Easy Installation and Interchangeability: Designed for straightforward mounting, even on surfaces machined by milling or grinding, and offers interchangeability for convenient maintenance.

3. Setup and Installation
The PMI linear guideway is designed for easy installation. High precision can be achieved even if the mounting surface is machined by milling or grinding, unlike conventional slide guides that require extensive scraping processes.
3.1 Mounting Surface Preparation
Ensure the mounting surface is clean, flat, and free from debris. Although the guideway is tolerant of less precise machining, optimal performance is achieved with well-prepared surfaces.
3.2 Securing the Linear Block
The linear block features multiple mounting holes for secure attachment. Use appropriate fasteners (not included) to firmly secure the block to the desired surface. Refer to the specifications section for detailed dimensions and bolt sizes.
4. Operating Principles
The PMI MSR series linear guideway operates on the principle of rolling motion, utilizing precision rollers instead of traditional balls. This design provides several operational advantages:
- Low Friction: The rolling motion significantly reduces frictional resistance, requiring less driving force and minimizing power consumption.
- High Speed Capability: Due to low friction and minimal temperature rise, the guideway is suitable for high-speed operations without compromising performance.
- Four-Way Load Bearing: The optimized geometric mechanics allow the guideway to effectively bear loads from all four directions: radial, reversed radial, and both lateral directions. This ensures stable and reliable operation under various load conditions.
- Enhanced Rigidity: The rigidity of the linear guideway can be further increased by applying preloading to the carriage or by incorporating multiple carriages in the system.
5. Maintenance
Proper lubrication is crucial for maintaining the high precision and extending the lifespan of the PMI linear guideway. The design facilitates easy lubrication.
5.1 Lubrication
Lubrication can be easily achieved by supplying grease through the grease nipple located on the carriage. Alternatively, a centralized oil pumping system can be utilized for continuous lubrication. Regular lubrication reduces frictional resistance and helps maintain accuracy over long periods of operation.
Consult the specifications for the recommended grease type and lubrication frequency based on your application's operating conditions.
6. Troubleshooting
This section provides general guidance for common issues. For complex problems, please contact technical support.
6.1 Reduced Smoothness or Increased Friction
- Check Lubrication: Ensure the guideway is adequately lubricated. Apply grease as per maintenance guidelines.
- Inspect for Debris: Foreign particles on the rail or within the block can impede smooth motion. Clean the system carefully.
- Verify Alignment: Improper alignment of the rail or block can cause binding. Re-check installation alignment.
6.2 Noise During Operation
- Lubrication: Insufficient lubrication can lead to increased noise.
- Loose Fasteners: Ensure all mounting bolts are securely tightened.
- Overload: Operating beyond the specified load capacity can cause excessive wear and noise.
