Product Description

Nabla Spring Blade is a direct rail fastening system engineered for enhanced performance on tracks with tight radius curves. With decades of proven reliability, this system is recognized for its straightforward installation and minimal maintenance requirements. By maintaining precise track gauge alignment, it significantly extends the service life of assembly components while providing superior electrical insulation and lateral force absorption capabilities.

Technical Features

High Clamping Force: Anchor screw ensures consistent 11 kN clamping force with wide torque range, preventing rail roll
Glass-Reinforced Material: Lateral insulators provide exceptional mechanical strength and lateral force absorption
Adjustable Insulators: Enables fine gauge tuning by 1.25mm increments (±7.5mm per rail seat)
Electrical Insulation: Provides insulation resistance exceeding 10 K Ohms

Product Advantages

Exceptional wear resistance from deep post insulator design reduces maintenance costs
Simple installation process saves time and labor expenses
Superior mechanical strength through glass-reinforced material construction
Enhanced electrical insulation outperforms comparable systems
Universal compatibility with all rail types including grooved, AREMA and industrial
Extended component lifespan by maintaining track gauge on tight radius curves
