OTIS Elevator Parts Escalator Chain Pitch 135.7mm
The OTIS Escalator Step Chain Pitch 135.7mm is a heavy-duty drive chain designed for OTIS commercial escalators and escalator modernization projects.
This step chain belongs to the same physical series as the commonly referenced 135.46mm / 135.47mm / 135.6mm step chains. Due to measurement tolerance, chain wear, manufacturing differences, or engineering drawing variations, some replacement chains may be identified as 135.7mm pitch.
The 135.7mm escalator step chain is widely used in OTIS high-traffic commercial escalators, especially the globally installed OTIS 506 series and 506NCE escalator systems.
