In the daily operations of warehousing and logistics, casters may seem insignificant, yet they are crucial components for improving efficiency. Whether it’s a cart for moving goods or a rack for storing items, the performance of casters directly impacts work pace and operational safety. Choosing the right casters can reduce workers’ effort and minimize equipment damage, while selecting the wrong ones may lead to frequent repairs and slowed progress. Today, we’ll explore several practical details that must be considered when selecting casters, based on the actual needs of warehouse scenarios.
1. Load capacity is the bottom line—never “overload” the system
In the warehouse, casters are subjected to various heavy loads daily, ranging from dozens of kilograms of cartons to palletized goods weighing several tons. When selecting casters, the first step is to accurately calculate the load. Here’s a simple formula: Total Load ÷ Number of Casters × 1.5 (safety factor). The resulting value represents the weight each caster must bear. For example, a handcart with a load capacity of 500 kilograms equipped with 4 casters requires each caster to have a minimum rated load of 500÷4×1.5=187.5 kilograms.
Many people opt for casters that barely meet the standards for convenience, but in storage environments, cargo stacking inevitably leads to deviations, and the impact from uneven floors can cause long-term “full-load” operation to result in caster frame deformation and wheel cracking. It is recommended to prioritize casters with thickened steel frames and high-elasticity polyurethane wheels, which are both wear-resistant and capable of cushioning load pressure.
2. The ground material determines the wheel hardness—don’t let “slippage” hold you back
Warehouse floors come in a wide variety, with concrete, epoxy flooring, and anti-slip tiles differing vastly in friction coefficients. When selecting casters, it’s essential to match them to the floor’s “personality.” Concrete floors are rough and prone to debris, making them suitable for nylon or cast iron casters with a hardness of 65 Shore D or higher. These options offer wear resistance, impact resilience, and are less likely to be punctured by sharp objects. Epoxy flooring is smooth but vulnerable to scratches, necessitating polyurethane casters with a hardness of 50-60 Shore D. These casters inherently provide quiet operation and leave no black marks. For wet environments like cold storage, rubber casters are more reliable due to their anti-slip properties, preventing carts from sliding on icy surfaces.
Additionally, pay attention to the wheel diameter. Under the same load, larger wheels (e.g., over 10 inches) require less effort to push compared to smaller wheels (under 5 inches), especially when the ground has slight bumps. Larger wheels can easily overcome these obstacles, while smaller wheels tend to get stuck.
3. Steering flexibility depends on bearings, frequent steering selects the right one
When shuttling between warehouse shelves, the steering flexibility of the wheels directly affects operational efficiency. Ordinary casters use ball bearings, which are suitable for linear handling; If frequent turns and U-turns are required, it is necessary to choose a universal wheel with precision bearings, preferably a double ball bearing design, which has low resistance during rotation and is easy for workers to push.
Another detail that is easily overlooked is the brake system of the casters. When loading and unloading goods or temporarily parking, the brakes must be able to firmly lock the wheels. It is recommended to choose casters with dual brakes, which can lock the rotation of the wheels and the steering shaft, to avoid accidental sliding of the cart on slopes or uneven ground.
4. Don’t ignore maintenance costs, easy to replace and repair are more worry free
Storage equipment is frequently used, and wheel wear is common. When choosing wheels, consideration should be given to whether they are easy to maintain in the future. Split design casters are more cost-effective than integrated ones. After the wheels wear out, only part of the wheels need to be replaced instead of the entire caster, which can save costs. In addition, the surface of the wheels should be smooth and without any patterns, which is convenient for daily cleaning and reduces the accumulation of dust and debris causing lagging.
If there are corrosive goods in the warehouse, attention should also be paid to the rust prevention performance of the wheels. Choose brackets that have been galvanized or sprayed on the surface, and choose polyurethane or nylon materials that are resistant to chemical

Choosing the right storage wheels does not require pursuing “high quality”, the key is to fit the actual usage scenario. By accurately calculating the load, looking at the ground, selecting the right bearings, and considering maintenance, the casters can become a “little helper” to improve storage efficiency, rather than a “troublemaker” who frequently encounters problems.
