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 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.

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.
