How to Choose Casters for 200-500kg Trolleys? Mid Heavy Duty Casters Are the Best Choice

When you’re looking for casters for trolleys that load 200-500kg, you may often fall into a dilemma: medium duty casters can't meet the load capacity requirement, while heavy duty casters are too heavy to use. This is a common pain point for many users who need to move medium-heavy loads—finding a caster that balances load capacity, usability, and cost is not easy.

Today, we’re here to solve this problem for you: our Mid Heavy Duty Casters are specially designed for 200-500kg trolleys, filling the gap between medium and heavy duty casters, and bringing you a more efficient and cost-effective solution.

For users who need casters for 200-500kg trolleys, wheel size and material are core factors affecting load capacity and usability. Our mid heavy duty casters have been optimized for these two points:

• Wheel Sizes: 3"x1.5", 4"x1.5", 5"x1.5", 6"x1.5" — these sizes are perfectly matched to 200-500kg load capacity, ensuring stable movement without being too bulky.
• Wheel Materials: PU wheels, TPR wheels, PP wheels, aluminum core PU wheels, high elastic wheels, etc. Each material has its own advantages: PU wheels are wear-resistant and quiet, TPR wheels have good shock absorption, PP wheels are lightweight and corrosion-resistant, and aluminum core PU wheels have higher load-bearing capacity—you can choose according to your actual use scenario.

Many users wonder: why not choose heavy duty casters if mid heavy duty casters are for 200-500kg? The answer lies in usability. Through our comparative test (see test picture below), we found that:

Our mid heavy duty casters are more effort-saving than heavy duty casters when starting to move. Heavy duty casters are designed for higher loads (above 500kg), so they are heavier in weight—this means you need to spend more force to push the trolley, which reduces work efficiency, especially for long-term use.

In contrast, our mid heavy duty casters focus on "balance": they have enough load capacity to bear 200-500kg, and at the same time, they are lighter in weight, making the trolley easier to start and move, greatly improving work efficiency.

Compared with other mid heavy duty casters on the market, our products have obvious competitive advantages, which can perfectly meet your needs for 200-500kg trolley casters:

• Competitive Price: We have our own production factory, which reduces intermediate links, so we can provide you with high-quality mid heavy duty casters at a more favorable price, helping you save costs.
• Virgin Material: We use 100% virgin material, which is not only ECO-friendly but also makes the wheel color brighter. More importantly, virgin material ensures higher load capacity and better working performance, avoiding the problem of easy damage caused by recycled materials.
• High-Quality Ball Bearing: Equipped with high-quality ball bearings, our mid heavy duty casters have higher load capacity, run smoothly, stably and quietly, and have a longer service life—reducing the frequency of caster replacement and saving maintenance costs.
• Customizable Mounting Top Plate: We provide European and American standard mounting top plates, which are compatible with most trolleys. At the same time, we support custom top plate sizes with small MOQ and low cost, solving the problem of mismatched top plates for special trolleys.
• Multiple Mounting Options: In addition to top plates, we also provide optional mounting functions such as threaded stem, bolt hole, solid round stem, etc., to meet different installation needs of your trolleys.
• Optional Thread Guards: Thread guards can effectively protect the caster’s internal structure, prevent dust, debris from entering, and further extend the service life of the casters.
• ECO-Friendly Plating & Corrosion Resistance: The caster brackets adopt ECO-friendly plating, which can pass the salt spray test for more than 24 hours. If you have higher corrosion resistance requirements, we can also make the wheels pass the 96-hour salt spray test, suitable for harsh working environments (such as humid, corrosive scenes).
