3. How to choose: Make quick decisions based on “priority”.
You can first identify 1-2 indicators that you care about, and then balance other indicators within an acceptable range.
For wear resistance + rolling effort saving (rough ground/outdoors/long distance): Nylon is preferred; if quieter and more floor-friendly are required, PU is preferred.
For silent operation + floor protection (hospitals/airports/shopping malls/office buildings): PU is preferred; rubber can be considered if stronger shock absorption is required.
When considering load capacity + comprehensive lifespan (heavy-duty frequent handling): prioritize high-quality PU (with appropriate hardness/wheel width/bearing); for rough floors, consider nylon or PU heavy-duty formulations.
The ground is prone to leaving black marks: it is advisable to choose the “non-marking PU/non-marking rubber” formula, and control the hardness of the wheel surface as well as its cleaning and maintenance.
4. 6 practical suggestions for improving wear resistance and lifespan (more crucial than material selection)
Selection based on dynamic load: Sufficient static load does not necessarily mean sufficient dynamic load. For high-frequency handling, it is recommended to leave a 20% to 30% dynamic load margin.
Reasonable wheel diameter and width: The larger the wheel diameter, the better for obstacle crossing and lower resistance; the wider the wheel width, the lower the unit pressure, resulting in better wear resistance and stability.
Bearings are as important as seals: while the wheel surface is wear-resistant, if water and dust enter the bearing, it will become “more and more stiff with use”, which is equivalent to early retirement.
Avoid long-term uneven loading and impact: Hard turning in place and frequent collisions with thresholds can accelerate the tearing of the wheel surface and deformation of the bracket.
Ground maintenance: Sand/iron chips are “wheel wear accelerators”. Regular cleaning of the channels and wheel surface entanglements can significantly impact the lifespan.
Correct braking and parking: For parking on a slope, it is recommended to use dual brakes or directional locking; for long-term parking, avoid deformation of the wheels due to pressure (support legs/blocks can be used).
5. Conclusion: Which One Is More Durable? Here’s a Sure-Fire Answer
If we only compare “pure wear resistance” (especially on rough surfaces and in situations where noise is not a concern), nylon is usually more durable; however, in most comprehensive working conditions, polyurethane exhibits a more balanced performance in terms of wear resistance, load-bearing capacity, noise reduction, floor protection, and tear resistance, making it the more common choice as the “go-to option for general wear resistance”. Rubber, with the right formulation, also performs well in terms of wear resistance, but its advantages are more biased towards shock absorption, noise reduction, and floor protection.
It is recommended to ultimately base your decision on your actual working conditions (ground, load, humidity/oil contamination, and pushing frequency). If necessary, conduct comparative tests using samples, as selecting the appropriate model based on data will provide greater stability.
