Product Description
PMI MSB linear motion guideway
PMI MSB Series is a line of heavy-duty linear guideways manufactured by Precision Motion Industries (PMI), designed for industrial applications requiring high load capacity, rigidity, and durability. The MSB Series is optimized for machinery subjected to heavy forces, such as CNC machines, presses, and large automation systems.
Features of MSB
The Original PMI MSB Heavy-duty Linear Guide offers unparalleled precision & durability with its high-load capacity, smooth motion, & long service life. Ideal for demanding industrial applications.
High Load Capacity
Larger rail widths (30 mm, 35 mm, 45 mm, etc.) compared to the MSA Series, enabling support for higher dynamic and static loads.
4-row ball bearing system for even load distribution across radial, axial, and moment forces.
Rigidity and Precision
Adjustable preload options (light, medium, heavy) to balance stiffness and smooth motion.
Ground raceways and precision-ground balls for consistent performance under heavy loads.
Durability
Hardened steel rails (HRC 58–62) and carriages for wear resistance in harsh industrial environments.
Optional seals or scrapers to protect against contaminants like metal chips, dust, and liquids.
Modular Design
Compatible with PMI accessories (end blocks, lubrication units) for easy customization.
Supports long-stroke applications with multi-rail configurations.
