- Wide-pallet designs
- Lubrication-free options
Main Drive Chain
Transfers motor power to the main drive shaft. Standard GB/T 1243 & ISO 606 roller chain.
- 08A to 32A, A & B series
- Simplex / duplex / triplex
- Escalator-dedicated FQ types

How to Replace an Escalator Step Chain
A six-step field procedure used by service engineers. Follow it and you avoid the two most expensive mistakes: single-chain replacement and wrong tension.
Lock Out and Measure the Existing Chain
Stop the unit, engage the main disconnect and mechanical brake, and hang a maintenance banner across both combs. Allow 30 minutes for residual oil temperature to drop below 40 °C before taking any measurement.
- Measure pitch across 10 links — never over a single link
- Record roller diameter, width between inner plates, pin diameter, plate thickness
- Count the links between two step shafts to confirm step pitch
- Photograph the side plates — maker’s marks usually identify the model
Confirm the Five Selection Parameters
Before ordering, lock in: pitch p, step pitch, roller diameter d1, width between inner plates b1 and pin diameter d2. These five values determine interchangeability — the maker’s model name does not.
- Check whether the machine is Japanese or European design (see the comparison below)
- Confirm the attachment type: W, D, Y or I
- Note the roller bearing code if present (6203 / 6204 / 6206)
Order a Matched Pair — Never One Chain
Step chains run in pairs. JB/T 8545-2010 requires step pitch synchronisation within 0.3 mm and chain length synchronisation within 0.3 mm across the pair. A new chain paired with a worn one will stretch unevenly and destroy both.
- Always order two chains of identical specification
- Specify the exact number of links, or the truss rise so we can calculate it
- Request the tensile class matching the duty: commercial or public transport
Pull the New Chain In With the Old
Break the old chain at the factory connecting link, then join the new chain to it and rotate the hand-wheel to feed the new chain through the track. This “piggy-back” method keeps the steps aligned and saves around 40 minutes per side.
- Use the factory connecting link — do not improvise
- Keep steps aligned throughout the pull
- Lubricate before first run unless the chain is a lubrication-free type
Set Initial Tension Correctly
Cold sag should be 1.0 – 1.2 % of the centre distance. For an 8 000 mm truss that is 80 – 96 mm of deflection at a 100 N push. Over-tensioning overloads the main reducer bearing and roughly doubles power consumption.
- Apply 100 N mid-span and measure deflection
- Existing sag before removal should be no more than 2 % of centre distance
- Torque the tension-carrier bolts to the maker’s value
Run In, Re-Tension and Inspect
Run the escalator unloaded for 15 minutes, stop, re-check tension and re-torque. Then inspect the step-chain rollers, the track and the comb engagement before returning the unit to service.
- Re-measure sag after the first hour of service
- Check chain wear with a wear gauge at the next scheduled visit
- Log the installation date, batch and heat number for traceability
The Five Parameters That Lock the Model
Send us these five measurements and we can identify your chain even without a part number.
Pitch
pCentre-to-centre distance between pins. Ranges 66.67 – 136.80 mm for step chains.
Step Pitch
tLength of chain needed for one step. Always an integer multiple of the pitch.
Roller Dia.
d125 – 80 mm. Japanese machines use small rollers, European machines large ones.
Inner Width
b1Width between inner plates. Determines sprocket fit and pin bearing pressure.
Pin Dia.
d2Affects both tensile strength and wear life. Lower pin pressure means longer life.
Japanese vs European / American Systems
The single most common cause of a wrong order. The two families are not interchangeable.
