Escalator spare part , roller outside link step chain - pitch 135.46, solid axles, oil lubricate
Background introduction
The vast majority of heavy-duty escalators use the step chain design of roller outside link. These kinds of escalator products are mostly used in places with high rise and heavy passenger flow, such as subways, transportation hubs and other places. Therefore, there are strong requirements for the safety and production quality control, the step chain which is the critical and safety component in the escalator drive system. After perennial use, if the step chain has worn out and reached its design service life, it must be replaced timely and propertly.

Product detail
Chain pitch P=135.46mm, 3P = step distance=406.4mm. The step chain is used oil for lubrication
The step chain is connected to its left and right sides by solid axles and the step chain width is 1000 mm. The solid axels are fixed with the chain link plate and are not datachable for transportation.
The step-chain rollers are made of hydrolytic resistant polyurethane. The step roller hub material is plastic as standard and metal hub is optional.The eligibility test for step-chain roller anti-hydrolysis is 250hrs, oil hydrolysis is 250hrs, and life test run time is 5000hrs.
