The escalator step chain is the core circulating and power transmission component of an escalator, which carries and drives the steps to run in a closed loop, directly determining the safety, stability and service life of the whole escalator system. It is manufactured with high-strength alloy steel, precision heat treatment and strict pitch control, featuring excellent wear resistance, fatigue resistance, stable meshing and low running noise.
We supply diversified escalator step chains to match different operating scenarios and load demands: Airport Escalator Step Chain, Metro Escalator Step Chain, Subway Escalator Step Chain, Public Transport Escalator Step Chain, High Traffic Escalator Step Chain, Heavy Duty Escalator Step Chain, Shopping Mall Escalator Step Chain, Supermarket Escalator Chain, High Speed Rail Escalator Step Chain, Transit Escalator Step Chain, Commercial Escalator Step Chain, Industrial Escalator Step Chain, Outdoor Escalator Step Chain, Semi-outdoor Escalator Step Chain and 24-hour Escalator Step Chain.
For high-flow transit hubs including airports, metro, subway and high-speed railway stations, our heavy-duty and high-traffic step chains are built to cope with continuous peak passenger flow, frequent start-stop and long-hour nonstop operation. Commercial-grade chains are ideal for shopping malls, supermarkets and commercial complexes, balancing stable performance and cost efficiency. For special working conditions, outdoor and semi-outdoor escalator step chains add anti-corrosion and moisture-proof treatment to adapt to rain, temperature change and dusty environment. Our 24-hour escalator step chain is specially optimized for non-stop operation scenarios, greatly extending overhaul cycles and reducing downtime. Industrial escalator step chains are customized for special industrial escalators with higher impact load requirements.
All our escalator step chains comply with EN81 and ISO9001 standards, with precise step pitch, consistent chain length tolerance and reliable tension performance. Whether you need new installation matching or old escalator renovation & replacement, we can provide reliable escalator step chain solutions for public transit, commercial, industrial and outdoor projects worldwide. 

how do I identify my escalator step chain?

Escalator step chain is a core component of the escalator drive system. It is widely used in commercial escalators in shopping malls, airports, metro stations and other public places. Subjected to cyclic load and continuous abrasion, it needs full replacement once it reaches the end of service life. 9300AE is a popular step chain model in the spare parts market.
Many buyers may order the wrong replacement chain if only referring to the escalator nameplate. The most reliable way to confirm the correct chain is to measure key dimensions with a caliper.
Before placing your order, please measure these parameters with a caliper:
✅ Pitch (P): Center-to-center distance between adjacent pins. The standard pitch of 9300AE step chain is 133.33 mm;
✅ Roller diameter (d1): Outer diameter of the roller;
✅ Roller thickness (h1): Axial width of the roller;
✅ Pin diameter (d2): Outer diameter of the connecting pin;
✅ Inner & outer link plate width (h2/h1): Height of inner and outer chain plates;
✅ Inner & outer link plate thickness (t/T): Plate thickness of inner and outer links.
