Component Specifications

Definition
A guide rail is a precision-engineered linear motion component that provides smooth, accurate, and repeatable movement along a defined path. In back gauge systems, it ensures precise positioning of the gauge relative to the cutting or bending tool, typically using ball bearings or rollers within a hardened steel track to minimize friction and maintain alignment under load.
Working Principle
Operates on the principle of linear motion with minimal friction, using recirculating ball bearings or rollers within a hardened steel rail and carriage block. The carriage moves along the rail with high precision, guided by the rail's geometry and preloaded bearing system to eliminate play and maintain accuracy.
Materials
Hardened steel (typically AISI 52100 or equivalent), stainless steel for corrosion resistance, aluminum alloy for lightweight applications, with optional coatings like black oxide or chrome plating
Technical Parameters
  • Width 15-45 mm
  • Height 15-35 mm
  • Length 500-3000 mm
  • Preload Light, Medium, Heavy
  • Load Capacity 5-50 kN
  • Accuracy Grade Normal (N), High (H), Precision (P), Ultra-Precision (UP)
  • Mounting Hole Pattern Standardized spacing (e.g., 60 mm centers)
Standards
ISO 10285, DIN 645

Frequently Asked Questions

What is the purpose of a guide rail in a back gauge system?

It provides precise linear movement and positioning for the back gauge, ensuring accurate material placement during cutting or bending operations.

How do I select the right guide rail for my application?

Consider load capacity, accuracy requirements, environmental conditions (e.g., dust, moisture), length, and compatibility with existing carriage blocks and mounting systems.

What maintenance is required for guide rails?

Regular cleaning to remove debris, lubrication of bearing systems (if not sealed), and periodic inspection for wear or damage to ensure continued precision.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
