Linear Guides – How to Choose the Best Solution?

ELFL or Monorail MR/BM?

Selecting the right linear guide system depends on many factors – from required precision and working conditions to the balance between cost, durability, and availability. At Rollico, we are often asked: which solution should I choose – ELFL carriages or Monorail MR/BM systems?

Our goal is always to match the guides to the actual application needs, achieving the optimal balance between reliability, cost, and system longevity.

When to choose ELFL carriages?

• when the application does not require ultra-high precision (e.g., guiding components in industrial automation, light transport systems),
• when the working environment is exposed to contaminants – ELFL is less sensitive to dust and particles,
• when lower cost and simplicity are key priorities.

When is Monorail MR/BM a better choice?

• for applications demanding the highest accuracy and rigidity (CNC, robotics, precision automation),
• under very high dynamic loads, where stability and long-term performance matter,
• in processes where precision is critical (optical, semiconductor, aerospace industries).

Summary

ELFL is a solid and cost-effective solution for clients who do not require extreme precision but value reliability and resistance to contaminants.
Monorail MR/BM, on the other hand, is the choice for the most demanding applications, where maximum accuracy, rigidity, and durability matter.

The key is always to match the solution to the actual project requirements. At Rollico, we assist in making this decision by analyzing the working conditions and client priorities to select the most efficient linear guide system.
