Escalator Spare Part Roller Inside Link Solid Axles Step Chain Pitch 135.46 Roller Dia 106.2

Background Introduction

In addition to being widely used in commercial escalators and normal public escalators, the inside roller step chains can also be used in heavy duty public escalators or high rise escalators whih have same performance and safety as outside roller step chain heavy duty public escalator. Due to heavy duty public escalators have intensive passenger flow, The ladder chain is required to have a large carrying capacity which include chain link plate, pin and step chain roller. So, the diameter of step chain roller is bigger than normal used step chain, similar as outside link step chain roller.  This kind of escalator products are common in subway, super high shopping plaza, transportation hub and other places. Based on this situation, the requirements for the quality, safety and reliability of the step chain are particularly strict. After long-term use, the chain has worn out, which exceeds its service life. The step chain must be changed timely and propertly to restore its service safety

Product Specification

Product Detail

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

The chain is connected to its left and right side link by solid axles or hollow axles. The solid axles step chain are fixed with chain link plate for transportation. The step chain width have type1000 for escalator width. And the step is fixed with step chain by index pin.

The step chain rollers are made by hydrolytic resistant polyurethane. The eligibility test of step chain roller include anti-hydrolysis 250 hours, oil hydrolysis 250 hours and life test running time 5000hours. The material of roller hub is polyamide 66

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.
