Clamping rail RM

Overview
Flexible multi-clamping rail system designed to increase machining productivity by enabling fast reconfiguration for different workpiece sizes. Multi-Rail RM accepts D- and B-series clamp modules and supports both smooth and serrated face variants for versatile fixturing.

Technical data

• Compatibility: D- and B-series clamp modules
• Maximum clamping force: up to 6 metric tons (60 kN)
• Serration pitch: 2.5 mm
• Profile size: 44 × 50 mm
• Standard rail lengths: 100–850 mm
• Positioning accuracy (serration to positioning hole): ±0.01 mm (up to RM-700)

Installation
Each Multi-Rail set listed includes the bolt set required for installation on a grid platform. For mounting to T‑slot tables, separate installation components are required and can be ordered separately.

Configuration options
Sets can be adapted by combining different modules from the Multi-Rail family to match specific workpiece dimensions and clamping requirements. Custom configurations are supported for non-standard part geometries.

Notes

• Nominal serration spacing is 2.50015 mm (for example, 200 serrations ≈ 500.030 mm) — account for this when programming stopper positions.
• The first locator hole can serve as a reference point for manual positioning or CAM programming.
