SKF TraX is a wheel-end bearing condition monitoring system for heavy vehicles, including trucks, trailers, and buses. By continuously measuring and analyzing wheel-end vibration, TraX detects early signs of bearing damage and provides actionable health insights.

TraX devices are available in two variants: Standalone and Connected. This documentation focuses on the Connected version, which is designed for integration with Telematics Service Provider (TSP) platforms.

How TraX Connected works

Step 1 – Platform integration

The Telematics Service Provider (TSP) integrates TraX Support into its platform using the available Web API and Queue API interfaces. This enables seamless data exchange between the SKF platform and the TSP platform.

Step 2 – Running TraX (end-to-end process)

1. Initial Setup (One-Time per Fleet)

The TSP registers the following entities in the SKF platform via TraX APIs:

  • Installers
  • Fleets
  • Vehicles

This establishes the digital structure required to manage devices and vehicle data.

2. Device installation (per device)

  • An installer mounts the device on the wheel end.
  • The device is commissioned using the TraX mobile app.
  • Upon commissioning, the device is automatically registered in both:
    • The SKF platform
    • The TSP platform

This ensures synchronization across systems without manual duplication.

3. Ongoing operation

  • During vehicle operation, TraX continuously monitors wheel-end health.
  • The device transmits status and diagnostic data to the SKF platform.
  • The TSP retrieves this data, processes it, and presents actionable wheel-end insights to fleet operators.
