Why should casters pay attention to “temperature resistance”? In a high-temperature workshop, choosing the wrong wheel can easily lead to premature failure.
In the selection of caster wheels, many companies prioritize bearing capacity, wheel diameter size, wheel surface material, and installation method.
But if the equipment operates for a long time in environments such as drying rooms, spraying lines, food processing, baking equipment, heat treatment workshops, etc., there is another parameter that must be confirmed in advance, which is the temperature resistance performance.
Many on-site issues are not due to insufficient load-bearing capacity of the casters, nor are the wheel surfaces not wear-resistant, but rather due to the use of environmental temperatures that exceed the applicable range of the caster material and structure. Once the temperature is ignored, the wheels may deform, crack, harden, become difficult to push, and even affect the safe movement of the entire equipment.
1. The impact of high temperature on casters is not just about being “a little hot”
Many people think that a high temperature environment will only make the surface of the wheels hot, but the actual impact is far more than that. Casters are composed of wheel surface, wheel core, bearings, brackets, lubrication parts, and fasteners, and the temperature tolerance of different components is not the same.
When the ambient temperature continues to rise, the wheel surface material may soften or age, the lubrication state of the bearing may change, and the metal structure may also affect the fit clearance due to thermal expansion and contraction. In the short term, no problems can be seen, but after long-term repeated use, the performance of the casters will gradually decline.
2. Which scenarios require more attention to heat-resistant casters?
If the device only occasionally passes through high-temperature areas, the impact may be limited. But if it is parked for a long time or frequently operated in high temperature environments, temperature resistance must be the focus of selection.
Common scenarios include: oven carts, food baking carts, spray drying lines, heat treatment trucks, disinfection equipment, industrial drying room turnover racks, and some production workstations near heat sources.
In these scenarios, the casters not only need to carry the equipment, but also maintain structural stability during continuous high temperatures, frequent starting and stopping, and repeated pushing.
3. Temperature selection cannot only focus on “high temperature”
When purchasing, some people may only ask, ‘How high can this wheel withstand?’ However, a truly professional selection should not only focus on peak temperature.
Because the temperature conditions faced by casters usually include three dimensions: high temperature, duration, and frequency of temperature rise and fall.
Short term exposure to high temperatures and long-term parking in high-temperature environments require completely different requirements. Occasionally entering the drying room and working continuously in the drying room every day have different tests on the wheels.
Therefore, when selecting equipment, it should be explained as much as possible whether it is for short-term use, intermittent use, or long-term exposure to high temperature environments.
4. Common Wheel Failure Symptoms in High Temperature Environments
The problem of caster caused by high temperature often does not occur suddenly, but gradually becomes apparent.
For example, the wheel surface begins to harden and become brittle, and the vibration increases when pushed; Local deformation of the wheel surface, resulting in jolts when the equipment moves; The bearing does not rotate smoothly, making it increasingly difficult to push forward; The brake mechanism is not flexible and the locking effect deteriorates.
When these phenomena occur, do not just judge it as “poor wheel quality”, but also check whether the usage environment exceeds the applicable working conditions of the wheels.
5. What are the details to consider when selecting heat-resistant casters?
Check if the wheel surface material is suitable for high-temperature environments. The stability of different materials at high temperatures varies, and ordinary casters cannot simply replace heat-resistant casters.
Secondly, check if the bearings and lubrication structure are compatible. High temperature environment may affect lubrication performance, thereby increasing rolling resistance.
Thirdly, check if the equipment has been parked at full load for a long time. High temperature combined with static pressure is more likely to cause deformation of the wheel surface.
Fourth, check if there are any temperature differences in the route used. Frequent entry from high temperature zones into normal temperature zones and repeated heating and cooling of materials can also affect their long-term lifespan.
6. An easily overlooked procurement misconception
Many companies believe that “we only occasionally pass through high-temperature areas, and ordinary casters should also be usable
But if the frequency of equipment passing through high-temperature areas is high, or if the dwell time is long each time, the cumulative impact cannot be ignored. Whether the casters are suitable for high temperatures depends not only on one use, but also on the long-term service life.
Therefore, it is important to clarify the temperature range, dwell time, frequency of movement, equipment weight, and whether braking is required before purchasing. The more complete the information provided, the more accurate the selection of casters.
