Features of MSA-S

The PMI MSA25S is a linear guide block from PMI's heavy-load MSA series, featuring a compact, square-type design. The "25" in the model name indicates the nominal rail size, and the "S" signifies a standard-length, square-type block. This configuration provides high rigidity and equal load-carrying capacity in all four major directions: radial, reversed radial, and both lateral directions.

High rigidity and equal load: 

The MSA series is designed with a 45° contact angle for its ball trains, which allows it to bear an equal load in all four directions. This makes the MSA25S block suitable for applications requiring high precision and resistance to bending moments.

Self-alignment:

Like other blocks in the MSA series, the MSA25S has a self-aligning capability, which can simplify the installation process.

Smooth movement: 

With a low coefficient of friction, the block's motion is very smooth, and the difference between dynamic and static friction is minimal. This prevents the "stick-slip" effect during sub-micron feeding, which is crucial for high-precision applications.

Optimized lubrication: 

A patented lubrication route ensures that lubricant is evenly distributed in each circulation loop, which helps improve running accuracy and extends the service life.

Interchangeability: 

The MSA series blocks and rails are interchangeable, providing greater flexibility in assembly and maintenance.

Mounting:

The square-type block is typically mounted from the top, providing a sturdy and reliable mounting interface. 

Application



The robust design and precision of the MSA25S make it an ideal component for a variety of industrial and automated systems:
  • CNC machine tools: Its high rigidity and precision are vital for machining applications.
  • Laser engraving and cutting machines: The smooth and precise movement is necessary for detailed work.
  • General automation equipment: Suitable for various automated systems where reliable linear motion is required.
  • Heavy-duty machinery: Can handle significant loads while maintaining high accuracy, making it useful in manufacturing plants and machinery repair shops
