Escalator Spare part, Step Chain, inside roller link, hollow axles, pitch 135.73

Background Introduction
The inside roller link step chain is used for commercial escalator. This type of step chain are used for 407.2mm step distance commerical escalator which are used in places with nornal passenger flow such as shopping mall, department stores, office buildings, hotels, hospitals, exhibition centers and airports, etc. The step chain is the safety and critical component in escalator. So, it's strong requirements for the safety and production quality control. After perennial use, if the step chain has worn out and reached its design service life, it must be replaced timely and propertly so that it can re.

Product Specification

Product Detail

This type of step chain pitch (P) is 135.73mm and step distance is 407.2mm (3P = step distance). This type of step chain is used oil lubrication.

The left side and right side link chain are pre-assembly, then are connected with long hollow axles. The hollow axles step chain is detachable design structure. It can be transportation with overall assmbly step chain which reft and right side link chain assembly with long hollow axles, or it can be split into left side, right side chain and hollow axles for transporation as option. By using this trasportation way, the step chain need to re-assembly before it install in jobsite escalator.

The step chain width have 1000, 800 and 600 for escalator type. And the fixing method of step and step chain have two structure design: index pin bush and plastic clampong bush.

The step chain rollers are made by hydrolytic resistant polyurethane and roller hub is used polyamide 66. As one of the critical part in step chain, it have been certified by eligibility test include anti-hydrolysis 250 hours, oil hydrolysis 250 hours and life test running time 5000hours.
