Background Introduction
The commercial escalator are used roller inside link step chain design. These kinds of escalator products are mostly used in places with commercial building with nornal passenger flow such as department stores, shopping mall, office buildings, hospitals, exhibition centers, hotels and airports, etc. Therefore, there are strong requirements for the safety and production quality control, the step chain which is the critical 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 Specification

Product Detail

Chain pitch P = 133.33mm, 3P = step distance = 400mm, step chain is used oil for lubrication.
The chain is connected to its left and right side link by hollow axles. Normally, the hollow axles are reserved and continue use, when change left and right side link chain. The left and right side link chain are same for type 1000, 800 or 600 escalator.

The single-strip links of the step chain are purchased independently and do not include the long axles, which are specified if required.

The step fixing design is to use the plastic clamping bushing.


The step chain rollers are made by hydrolytic resistant polyurethane and roller hub material is usd PA66. The eligibility test of step chain roller include anti-hydrolysis 250 hours, oil hydrolysis 250 hours and life test running time 5000hours.

Producti and Quality Control

The step chain productio by Industry-Renowned step chain suppliers. The entire step chain manufacture process includes meterial imgress, component machining, part heat treatment and final assembly with quality control plan to eansure each step chain achieved original design requirement. The quality level is consistent with international first-class brand escalator step chain.

All type step chain achieved CNAS type test certificate.

Our service
Our professional engineering team can provide technical support to help clients identify the appropriate step chain specifications to meet safety and lifetime requirements.

We kindly request our clients to provide us with any documents related to the escalator chain, e.g. technical service reports, spare parts numbers of the chain, drawings of the chain, breakage load certificates/breakage load calculations, etc. These documents can considerably speed up an inquiry and clarify discrepancies. To avoid any risk of providing a non-functioning chain, complete this questionnaire and an identification template with detailed photographs of the link plates, rollers, step pins, axles, axle parts and markings on the components. Please fill in the following points and chain templates as completely as possible. If the template deviates from the chain to be measured, sketch, measure and photograph the deviation in detail.
