Choosing Casters for Warehousing and Logistics? Pay Close Attention to These Practical Details
Time：Aug 12,2025
In the daily operation of warehousing and logistics, casters may seem insignificant, but they are key components for improving efficiency. Whether it's a hand truck for moving goods or a shelf for storing goods, the performance of the casters directly affects the work rhythm and operational safety. Choosing the right casters allows workers to exert less effort and reduces equipment damage; choosing the wrong ones may lead to frequent repairs and slow down progress. Today, starting from the actual needs of the warehousing scene, let's talk about several practical details that must be considered when selecting casters.
Load capacity is the bottom line; never "overload".
Casters in warehouses have to deal with various heavy objects every day, ranging from dozens of kilograms of cartons to tons of pallet goods. When selecting casters, the load must first be calculated accurately. Here's a simple formula: Total load ÷ Number of casters × 1.5 (safety factor). The resulting value is the weight that a single caster needs to bear. For example, a hand truck with a load capacity of 500 kilograms and 4 casters requires each caster to have a rated load of at least 500 ÷ 4 × 1.5 = 187.5 kilograms.
Many people choose casters that just meet the standard for convenience, but in a warehouse environment, the stacking of goods is inevitably biased, and the impact force from uneven ground adds to the problem. Long-term "full-load" operation easily leads to caster bracket deformation and wheel cracking. It is recommended to prioritize casters with thickened steel plate brackets and high-elasticity polyurethane wheels, which are both wear-resistant and can buffer the load pressure.
Ground material determines wheel hardness; don't let "slipping" slow you down.
Warehouse floors vary widely. The coefficient of friction between cement floors, epoxy floors, and anti-slip tiles is vastly different. When choosing casters, you need to follow the "temperament" of the ground. Rough cement floors are prone to stones and are suitable for nylon wheels or cast iron wheels with a hardness of 65 Shore D or higher, which are wear-resistant and impact-resistant and are not easily punctured by sharp objects; smooth epoxy floors are afraid of scratches and require polyurethane wheels with a hardness of 50-60 Shore D, which are quiet and will not leave black marks; in cold storage or other humid environments, rubber wheels are more reliable in terms of anti-slip performance and can prevent hand trucks from slipping on icy ground.
Also pay attention to the wheel diameter. Under the same load, larger diameter wheels (such as 10 inches or more) are easier to push than smaller wheels (5 inches or less), especially when the ground has slight bumps. Large wheels can easily cross them, while small wheels are easily stuck.
Turning flexibility depends on the bearing; choose the right one for frequent turning.
When shuttling between warehouse shelves, the turning flexibility of the casters directly affects operational efficiency. Ordinary casters use ball bearings, suitable for linear transportation; if frequent turns and U-turns are required, casters with precision bearings should be selected, preferably a dual ball bearing design, with low rotational resistance, making it effortless for workers to push.
Another easily overlooked detail: the caster's braking device. When loading and unloading goods or temporarily parking, the brakes must firmly lock the wheels. It is recommended to choose casters with dual brakes, which can lock both wheel rotation and the swivel axis, preventing the hand truck from accidentally sliding on slopes or uneven ground.
Don't ignore maintenance costs; easy replacement and repair are more convenient.
Warehouse equipment is used frequently, and caster wear is common. When choosing casters, consider whether later maintenance is convenient. Separable casters are more cost-effective than integral casters. When the wheels wear out, only the wheel part needs to be replaced, not the entire caster, saving costs. In addition, the wheel surface should be smooth and without texture, making it easy to clean and reducing jams caused by dust and debris accumulation.
If the warehouse contains corrosive goods, pay attention to the anti-rust performance of the casters. Choose brackets that have been galvanized or spray-coated, and wheels made of chemically corrosion-resistant polyurethane or nylon to avoid rusting brackets and cracked wheels after long-term use.
Choosing the right warehouse casters doesn't mean pursuing the "most expensive and best"; the key is to match the actual usage scenario. Calculating the load, checking the ground, selecting the bearing, and considering maintenance—if these four details are done well, the casters can become a "little helper" that improves warehouse efficiency, rather than a frequent "troublemaker".
