CNAS Roller Outside Link Spare Part Step Chain Escalator With Plastic Bush

Background introduction

The vast majority of heavy duty escalators adopt the design of step chain with roller outer chain. This kind of escalator products are mostly used in high buildings and places with large passenger flow, such as subways and transportation hubs, etc. place. Therefore, there is a strong requirement for the safety and production quality control of the step chain, the key and safety components in the escalator drive system. After prolonged use, if the step chain has worn out and reached its designed service life, it must be replaced promptly and reliably.

Product Specification

Product detail

Step Chain pitch P=135.46mm, 3P = step distance=406.4mm, The step chain lubrication is used oil.

The step chain is connected to its left and right sides by hollow axles. The step chain width is type 1000 for escalator width. The design structure is detachable connection by using hollow axles to connect left and right side link for transportation. Generally, the length of each chain is divided into 10 folds, 2 folds and offset link base on contract specified.

​The step-chain rollers are made of hydrolytic resistant polyurethane. And the step chain roller hub is used PA66. All step chain roller passed the eligibility test of anti-hydrolysis is 250hrs, oil hydrolysis is 250hrs, and life test run time is 5000hrs.
