SKF
Roller Encoder Units
SKF roller encoder units integrate a multi-pole magnetic encoder ring into a roller bearing seal, paired with a stationary sensor mounted on the housing. They deliver speed and directional signals for belt conveyors, chain conveyors, and material transport systems. The encoder is robustly sealed against dust, moisture, and vibration, providing a maintenance-free sensing point directly from the bearing. These units are widely used in mining, quarrying, and bulk handling facilities where reliable speed monitoring is essential for production control and detecting stalled or slipping conditions. The simple installation — no need for separate targets — reduces mechanical complexity and the risk of damage in harsh environments.

Trusted by Industry Leaders
Rugged, Sealed Design
Withstands abrasive dust, mud, and washdown.
Direct Mount Sensing
Sensor rides on bearing, eliminating alignment issues.
Speed and Direction Output
Digital signals for PLC or monitoring system.
Easy Retrofit
Replace standard bearing with encoder unit; no mechanical modifications.
Long Service Life
Labyrinth-protected encoder remains clean.
Conveyor Stalling Detection
Immediate alert when speed drops below threshold.
Conveyor Belt Speed Monitoring with Roller Encoder Units
In mining, slip detection protects against belt fires. SKF roller encoder units mounted on idler or tail pulleys feed real-time speed data to the safety system, triggering alarms or shutdown if deviation exceeds limits, enhancing workplace safety and production continuity.
Compatibility with SKF IMx and Cloud Systems
The analog or digital signals integrate with SKF condition monitoring hardware and software, adding speed data to vibration analysis for comprehensive asset health management.
