LRM Series Miniature Type Linear Guide
The LRM series linear guides are precision miniature linear guides engineered for compact motion systems where space limitations prevent the use of standard linear guide rails. Designed for small-scale automation and positioning applications, the LRM Series delivers smooth, controlled linear motion with accuracy within a reduced mechanical footprint.
These stainless steel miniature linear guides feature corrosion-resistant rails and blocks, making them suitable for environments where durability and reliability are critical. The compact design supports precise positioning while maintaining low-friction movement and quiet operation.

The LRM Series: Compact Equipment Design
The LRM series linear guides are designed for compact equipment that requires reliable, precise linear motion under light to moderate loads. Their small profile makes them well-suited for motion assemblies where traditional guide rails would be oversized.Available in sizes LRM5 through LRM15, these miniature linear guides provide stable motion control within tightly constrained mechanical layouts.
Common application environments include:
- Medical devices and diagnostic instruments
- Optical inspection systems
- Semiconductor manufacturing equipment
- Compact automation systems
- 3D printing platforms
- Small positioning stages and motion assemblies
The compact form factor and corrosion-resistant materials make stainless steel miniature linear guides a practical solution for precision equipment operating in controlled environments.
LRM Miniature Linear Guide Design & Performance Features
The LRM series linear guides incorporate several design elements that support consistent motion accuracy and reliable operation.Gothic Arch Groove Design
- Raceways feature a Gothic arch profile that creates four-point ball contact.
- This configuration enables equal load capacity in four directions: up, down, left, and right.
Stable Motion in Multiple Orientations
- Balanced load distribution supports stable performance regardless of mounting orientation.
Block Type Options
- Standard Block (N) – Compact design for general miniature motion assemblies.
- Long Block (L) – Extended block length provides improved stability and higher load support.
Preload Options
- Clearance (A) – Standard clearance configuration for smooth movement.
- Light Preload (B) – Adds additional rigidity for improved positioning stability.
Material Construction
- Manufactured from martensitic stainless steel for corrosion resistance and long-term durability.
Operating Temperature
- Maximum operating temperature: 80°C
- Momentary temperature limit: 100°C
Lubrication & Maintenance for LRM Series Linear Guides
The LRM series miniature linear guides are supplied pre-lubricated with lithium soap-based grease (ISO VG32–68) to ensure smooth motion during initial operation.Grease is applied during manufacturing to provide adequate lubrication for startup and early operating cycles. Periodic lubrication is recommended to maintain consistent motion performance and minimize wear over time.
Typical maintenance guidance includes:
- Re-lubrication after approximately 100 km of travel, or
- Every 3–6 months, depending on operating conditions and duty cycle.
