In hydraulic home lifts, guide rollers play an important role in keeping the platform or lift carriage moving smoothly along the guide rails.
For many years, we used rubber-coated guide rollers on our home lifts. There was a good reason for this choice: rubber provides a smooth and relatively quiet running experience.
Compared with harder materials, rubber has good elasticity and cushioning characteristics. When the roller runs along a T-shaped guide rail, it can help reduce running noise and make the movement feel smoother.
For many years, this solution worked well in our home lift applications.
However, one installation in Nigeria made us take a closer look at the long-term performance of rubber guide rollers in hot climates.
The Problem: The Rubber Coating Kept Coming Off
Last year, we supplied a home lift to a customer in Nigeria.
After the lift had been installed and put into operation, the customer reported an unusual problem:
The rubber outer layer of the guide roller repeatedly came off during operation.
At first, we considered the most common mechanical possibilities.
Could the roller have been installed incorrectly?
Could the roller have been misaligned with the guide rail?
Could the rubber surface have been rubbing against a bolt, screw, bracket, or another metal component?
These were reasonable possibilities, because incorrect installation or interference can certainly cause abnormal wear on a guide roller.
So we discussed the situation carefully with the customer and asked him to inspect the installation and operating conditions.
The customer provided an important observation.
The Key Factor: The Local Operating Environment
The lift was installed in Nigeria, where temperatures can remain very high for long periods of the year.
According to the customer's analysis, the local high-temperature environment was likely contributing to the problem.
The basic situation was:
High ambient temperature → softer rubber → continuous contact with the T-shaped guide rail → increased wear → rubber layer eventually peeling away.
This explanation made sense when we considered the actual operating environment.
Rubber is flexible and relatively soft, which is one of the reasons it provides a quiet and comfortable running experience.
But that same softness can become a disadvantage under certain environmental conditions.
In a hot climate, the rubber material can become softer. When the lift operates repeatedly, the roller is continuously in contact with the guide rail. Over time, the combination of heat, pressure, movement and friction can accelerate wear of the rubber surface.
This does not necessarily mean that rubber guide rollers are unsuitable for home lifts in general.
Rather, it showed us that the material selection needs to take the installation environment into account.

We Contacted the Guide Roller Manufacturer
Instead of simply replacing the roller and continuing with the same design, we contacted the manufacturer of the guide rollers and explained the problem in detail.
We asked whether there was another roller material that could provide good running performance while offering better resistance to heat and long-term wear.
The manufacturer recommended another option:
Polyurethane guide rollers.
This gave us an opportunity to compare the two solutions.
Rubber vs. Polyurethane Guide Rollers
The original rubber roller had one major advantage: quiet operation.
That was exactly why we had originally selected it.
However, the polyurethane roller offered a different advantage.
The polyurethane material is permanently bonded to the steel roller body, creating a much more robust roller construction.
Instead of relying on a relatively soft rubber outer layer that could potentially peel under certain conditions, the polyurethane coating is firmly integrated with the metal roller structure.
This significantly reduces the risk of the outer material separating from the steel core during normal operation.
For us, this was an important improvement.
But we still needed to test it ourselves.
Testing the New Polyurethane Rollers
We decided to install the polyurethane guide rollers on a home lift and observe the running performance.
One of our concerns was obvious:
Would polyurethane be noticeably louder than rubber?
After all, reducing running noise was one of the main reasons we had originally chosen rubber rollers.
The test results were encouraging.
The polyurethane rollers operated smoothly, and the running noise was still at a satisfactory level.
They did not produce the kind of significant metal-on-metal noise that we wanted to avoid.
At the same time, the polyurethane roller construction provided a much more robust solution for demanding environmental conditions.
This gave us confidence to move forward with the change.
From One Customer Problem to a Product Improvement
The most important part of troubleshooting is not simply fixing one machine.
The real value comes from asking:
How can we prevent the same problem from happening again?
After evaluating the problem, discussing it with the customer, consulting the roller manufacturer and testing the alternative design, we decided to make a broader change.
Starting from the end of last year, we began replacing the rubber guide rollers with polyurethane guide rollers on our newly produced home lifts.
In other words, this was not simply a replacement for one customer.
It became a design improvement applied to our subsequent home lift production.
Why We Changed to Polyurethane Guide Rollers
The decision was based on several practical considerations.
1. Better resistance to high-temperature environments
Polyurethane is a better choice for applications where the guide roller may be exposed to elevated ambient temperatures.
This is particularly important for home lifts installed in hot regions.
2. Stronger connection between the coating and steel roller
The polyurethane material is firmly bonded to the steel roller body.
This greatly reduces the possibility of the outer material separating from the roller during operation.
3. Good running performance
After testing, we found that the polyurethane rollers still provided smooth movement and acceptable noise levels.
This allowed us to improve durability without sacrificing the running experience that we wanted from our home lifts.
4. Better long-term reliability
A guide roller is a relatively small component, but its performance can have a direct effect on the movement and stability of the lift.
Improving the roller material can therefore contribute to more reliable long-term operation.
What We Learned From This Troubleshooting Case
This experience reminded us of an important principle in equipment design:
A component that performs well in one environment may not necessarily be the best choice for every environment.
Our rubber guide rollers had been used successfully for many years and in many installations.
There was nothing fundamentally wrong with the original design.
The problem appeared when the product was used under a different combination of environmental conditions.
In this case, the combination of:
-
high ambient temperature,
-
continuous roller-to-rail contact,
-
repeated lift operation,
-
pressure on the roller,
-
and the characteristics of the rubber material
created a condition where the rubber coating could wear and eventually peel away.
Instead of treating the problem as an isolated failure, we used it as an opportunity to improve the product.
Troubleshooting Should Lead to Prevention
When a customer reports an unusual problem, our first objective is always to understand why it happened.
Was it installation?
Was it alignment?
Was it the mechanical structure?
Was it the operating environment?
Was it the material?
Or was it a combination of several factors?
In this case, investigating those questions led us from an individual customer complaint to a change in our component selection.
That is the real purpose of troubleshooting.
Fix the immediate problem — understand the root cause — improve the design — prevent recurrence.
Our Current Approach
Today, our newly produced home lifts use polyurethane guide rollers instead of the rubber rollers we previously used.
The change was driven by a real-world application, verified through testing, and then incorporated into our production process.
For customers installing home lifts in hot climates, this type of material selection can be particularly important.
A home lift is not only a combination of a hydraulic power unit, platform, guide rails and control system. Small components such as guide rollers can also have a significant influence on the long-term operating experience.
This case is a good example of why we continue to review our components based on actual field experience.
Sometimes, the best product improvements come from a problem that happens in the real world.
And sometimes, one customer's experience can help make every future machine better.
