SMH50623483 Escalator Handrail Speed Sensor Roller 109×31×6204 with 6204 Deep Groove Ball Bearing for Schindler 9300 9500 9700 Systems
SMH50623483 Escalator Handrail Speed Sensor Roller
The SMH50623483 is a critical handrail speed sensor roller designed for Schindler escalators and moving walks. This precision-engineered component (109×31×6204 guide support wheel) monitors handrail belt speed to ensure synchronization with step/pallet movement, preventing safety hazards caused by speed discrepancies. With dimensions of 109mm outer diameter × 31mm width and equipped with a 6204 deep groove ball bearing, this roller ensures smooth rotation, accurate speed detection, and long service life in continuous operation environments.
Key Features
- Speed Monitoring Function: Detects handrail speed to ensure 0~+2% synchronization with steps (per GB16899/EN115 standards)
- Multi-Role Design: Functions as speed sensor roller, guide wheel, and pressure roller simultaneously
- Precision Bearing: 6204 bearing with 20mm bore diameter for smooth, low-friction rotation
- Durable Construction: Metal and plastic composite materials withstand heavy-duty escalator environments
- Direct Compatibility: Fits Schindler 9300, 9500, and 9700 escalator series
- Safety Critical: Triggers escalator stop when handrail speed drops 15% below step speed for 15+ seconds
