The SMH50623483 is a critical handrail speed sensor roller designed for 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 9300, 9500, and 9700 escalator series
Safety Critical: Triggers escalator stop when handrail speed drops 15% below step speed for 15+ seconds
Safety Critical Component: Essential for ASME A17.1/CSA B44 and EN115 code compliance for escalator handrail speed monitoring
Triple Function: Combines speed sensing, guidance, and pressure application in one compact roller
Precision Engineering: 109mm OD and 31mm width optimized for 9300/9500/9700 series geometry
Quality Bearing: 6204 bearing rated for 20,000+ hours continuous operation in escalator environments
Drop-in Replacement: Direct fit for OEM part SMH50623483 - no modifications required
Global Standards Compliance: Meets Chinese GB16899, European EN115, and North American ASME safety standards
