CUSTOMIZED SOLUTIONS
Industrial casters are widely used in heavy machinery, medical equipment, warehousing and logistics, and other fields. Their performance is directly related to the operational safety and efficiency of the equipment. Impact resistance, as a key indicator of caster quality, is increasingly valued by caster users and buyers. This article focuses on impact resistance testing for industrial casters, providing an in-depth analysis of testing standards, methods, influencing factors, and optimization strategies. It also incorporates purchasing recommendations from caster suppliers to help users make informed decisions.
Casters are used in complex industrial environments, with uneven floors and frequently fluctuating equipment loads. Sudden impacts and collisions are common. Inadequate impact resistance can easily lead to tire rupture, bracket breakage, and even equipment overturning.
Improving Safety: High-intensity impacts can easily lead to safety incidents, and testing helps select more reliable products.
Extending Service Life: Testing casters with high impact resistance reduces the frequency of replacement due to damage. Optimizing Design: Test results provide caster manufacturers with guidance for structural improvements.
Meeting Industry Standards: Large-scale project procurement often requires impact test reports.
| Industry Category | Usage Scenario | Impact Resistance Requirements |
| Medical Equipment | Surgical Carts, Hospital Beds, Testing Equipment | Medium |
| Logistics and Warehousing | Warehouse Trucks, Forklifts, Shelving Equipment | High |
| Engineering Manufacturing | Industrial Equipment, Work Trolleys | High |
| Aerospace Manufacturing | Assembly Line Trolleys, Material Handling | High |

The static impact test is the most basic testing method. It simulates impact force by dropping a weight onto the caster from a certain height to test for damage. The test steps are as follows:
Secure the caster to a metal test platform;
Release a standard weight from a predetermined height;
Inspect the caster structure for cracks, debonding, or deformation;
Repeat the impact 10 times and inspect for residual deformation.
Compared to static testing, dynamic impact testing is more realistic. It simulates the impact of a loaded caster encountering an obstacle (such as a pothole or step) to test its resistance.
The test process includes:
Setting up the rails and obstacle;
Having the caster pass over the obstacle at high speed;
Repeating the impact cycle hundreds of times;
Recording the wear of the tires, brackets, and bearings.
| Test Type | Impact Mode | Simulation Realism | Typical Applications |
| Static Impact | Vertical Heavy Object Impact | Medium | Medical, Exhibition Equipment |
| Dynamic Impact | Mobile Vehicle Impacting an Obstacle | High | Industrial, Logistics |
| Field Testing | Simulation of Actual Use Environments | Extremely High | Custom Caster Products |
Wheel Materials: High-elastic polyurethane (PU), nylon, TPR, rubber, and other materials have varying impact absorption properties. Polyurethane offers excellent cushioning and is suitable for frequent impacts.
Bracket Materials: Cast iron, stainless steel, cold-rolled steel, and other materials determine the bracket's strength and crack resistance.
A larger wheel will better distribute impact force and reduce single-point stress. A wider wheel increases the contact surface and also contributes to stable operation.
| Caster Size | Impact Resistance | Recommended Usage Scenarios |
| 3 inches | Low | Light-load Mobile Equipment |
| 4-5 inches | Medium | General Industrial Transport Equipment |
| 6 inches and above | High | Heavy Machinery, Engineering Platform Equipment |
Impact-resistant casters generally utilize a dual-bearing structure or reinforced steel ball bearings and are bolted together, significantly improving caster stability and impact absorption.
Adding Reinforcement Ribs;
Double-Layer Bracket Structure;
Selecting Heat-Treated Steel;
Optimizing Hub Thickness Design.
Some high-end impact-resistant casters incorporate rubber bumpers and spring buffer modules to effectively absorb instantaneous impact forces.
Brackets are spray-coated, electroplated, or hot-dip galvanized to enhance corrosion resistance and prevent structural weakness caused by rust.
When choosing casters, consider not only price but also the impact risk of the intended use scenario. Purchasing recommendations include:
Clarify the load rating: Larger wheel diameter casters are recommended for high-load scenarios.
Understand the surface conditions: The more uneven the surface, the higher the impact resistance required.
Focus on structural strength: A full metal frame + PU tire combination is preferred.
Check test reports: Request a third-party impact test report when purchasing casters.
Choose a high-quality caster supplier: Giessen, for example, offers a variety of industrial-grade, impact-resistant casters that have undergone extensive testing.
