LGC Series Crossed Roller Way Linear Guides

The LGC series crossed roller way is engineered for precision motion applications requiring exceptionally smooth, controlled linear travel. As a LGC series linear guide, this crossed-roller design fundamentally differs from traditional recirculating ball-type linear guides, delivering higher rigidity and finer positioning performance within a compact footprint.

Designed for applications where accuracy and motion stability are critical, this precision crossed-roller guide provides consistent, predictable motion for fine positioning systems. Its structural configuration supports stable load handling while maintaining compact system integration.

What Makes Crossed Roller Guides Different?

Unlike ball-type systems, the LGC series crossed roller way uses cylindrical rollers arranged in a 45° crossed configuration between the rail and carriage.
Key mechanical distinctions include:
  • Rollers positioned alternately at right angles
  • Line contact between roller and raceway (rather than point contact)
  • Balanced load distribution across multiple directions
Line contact increases rigidity and enhances stable load support. Because of the crossed-roller orientation, the linear guide maintains equal load capacity in the vertical, horizontal, and moment directions, making it well-suited for multidirectional precision motion.

Non-Recirculating Roller Design

A defining feature of the LGC series linear guide is its non-recirculating roller architecture. The cylindrical rollers do not travel through return paths as found in recirculating ball-type systems.
This design:
  • Eliminates pulsation associated with ball return transitions
  • Reduces vibration during travel
  • Promotes exceptionally smooth, continuous motion
For applications requiring repeatable micro-positioning and controlled incremental movement, the non-recirculating structure provides a measurable advantage in motion stability and surface finish quality.
This smooth, vibration-reduced operation is the primary differentiator of the LGC series crossed roller way.

LGC Series Linear Guide Configuration Options

The LGC series linear guide is available in multiple rail configurations to accommodate varying load and space requirements:

3-Rail configuration

  • Compact and space-efficient
  • Suitable for applications with tighter envelope constraints

4-Rail configuration

  • Increased rigidity
  • Higher load support capability
These configuration options allow system designers to balance footprint constraints with structural performance requirements.

LGC Series Crossed Roller Way Applications

The precision crossed roller guide is commonly used in:
  • Photonics alignment systems
  • Wire bonding equipment
  • Medical microtome and tissue slicing equipment
  • Precision laboratory instruments
  • Fine positioning assemblies
Its smooth motion characteristics and multidirectional load stability make it ideal for equipment where positioning accuracy and repeatability are critical.
