Mitsubishi Escalator Step Roller J622000C201

J622000C201 is commonly used in Mitsubishi escalator step running systems.

This roller is generally installed inside the escalator step assembly and works together with the guide track during continuous escalator operation.

According to maintenance market information, this model is commonly associated with 76×35×6202 roller structures used in Mitsubishi J series escalators.

Common Field Situation

In shopping malls and airport projects in Romania and Malaysia, step roller wear is one of the more common escalator maintenance situations after long-term operation.

Typical field symptoms may include:

• abnormal rolling noise
• step vibration during operation
• uneven step movement
• increased track friction
• intermittent step impact sound

During overhaul work, technicians sometimes replace multiple rollers together instead of replacing only a single damaged unit.

Why Step Rollers Matter

The step roller directly affects:

• escalator running smoothness
• step chain movement stability
• passenger ride comfort
• guide track wear condition

If roller wear becomes uneven, long-term vibration may gradually increase inside the escalator running system.

Because of this, many maintenance companies inspect roller condition during periodic escalator servicing.

Practical Maintenance Notes

In some older Mitsubishi escalators, maintenance teams replace the step roller together with:

• step chain rollers
• guide tracks
• step axles
• bearing assemblies

depending on operational wear condition.

Some Mitsubishi step rollers use 6202 bearing configurations for long-term continuous operation.

FAQ

Why does the escalator make rolling noise during operation?

In some escalator systems, worn step rollers or uneven bearing wear may gradually increase running noise and vibration.

Can damaged step rollers affect escalator comfort?

Yes. Roller wear may influence step movement smoothness and passenger riding stability during continuous operation.

Installation Notes

Before replacement:

• roller dimensions should match original specification
• bearing type must be confirmed carefully
• guide track wear should also be inspected

Some Mitsubishi escalators use different roller thickness configurations depending on escalator generation.
