CUSTOMIZED SOLUTIONS
With the advancement of modern medicine, equipment such as CT, MRI, X-ray machines, and ultrasound imaging systems are becoming increasingly mobile to meet the needs of different departments and complex environments. Mobile imaging equipment requires the following features:
High mobility: enabling flexible maneuvering within confined spaces.
Smooth movement: preventing vibration from affecting image quality.
Secure locking: ensuring the equipment is securely fixed during operation.
Compared to ordinary industrial casters, medical casters have higher performance and standards requirements:
Load Capacity: Mobile imaging equipment is typically large and can weigh hundreds of kilograms, requiring casters with strong load-bearing capacity.
Anti-static performance: preventing static electricity from interfering with sensitive electronic components.
Chemical resistance: Disinfectants and cleaning agents are often used in hospitals, so the caster surface must be corrosion-resistant.
Low noise: The caster remains silent during movement to avoid disturbing medical staff and patients.
These characteristics make medical casters more than just "mobile components"; they are also key to the reliability and safety of equipment.
Medical casters can be broadly divided into the following categories based on their function and structure:
| Caster Type | Features | Application Scenarios |
| Fixed casters | Only linear movement, high stability | Bases for heavy medical equipment |
| Swivel casters | 360° rotation, high flexibility | Mobile imaging equipment, small examination carts |
| Brake casters | Mechanical or foot-operated brakes | Imaging tables that require a fixed position |
| Anti-static casters | Made of conductive materials to prevent static electricity accumulation | High-precision electronic equipment such as MRI and CT scans |
Choosing the right caster combination is key to ensuring smooth and safe equipment movement.
Medical casters typically consist of the following components:
Tread Material: Polyurethane (PU), thermoplastic rubber (TPR), conductive rubber, etc. Bracket Structure: Made of high-strength steel or stainless steel, some also use aluminum alloy to reduce weight.
Bearing System: Ball bearings ensure low friction and quiet operation.
Locking Device: Available in three categories: single-wheel lock, dual-wheel lock, and all-around lock.
Mobile X-ray equipment is widely used in emergency rooms, ICUs, and wards. Its caster requirements include:
High maneuverability to facilitate maneuvering in confined spaces;
High load-bearing capacity to support the heavy equipment body;
Excellent shock absorption to minimize interference with images during movement.
Mobile CT scanners are typically used in operating rooms or large-scale events, placing even higher demands on their casters:
Anti-static function is required to prevent interference with imaging signals;
A dual-wheel locking system is required to ensure stability during operation;
Extremely low noise levels are required to minimize impact on the surgical environment.
Compared to CT and X-ray machines, ultrasound equipment is lighter, but requires greater flexibility and quietness.
It uses universal silent casters;
It is mostly made of TPR soft rubber to prevent wear on the floor;
It is equipped with a brake system to facilitate quick positioning by the doctor.
In the medical industry, casters are typically required to undergo rigorous performance testing, including:
| Test Items | Test Content | Evaluation Criteria |
| Load Capacity | Static/Dynamic Load Test | ≥ 120% of the equipment weight |
| Abrasion Resistance | Continuous Rolling Test | ≥ 50,000 cycles without noticeable wear |
| Corrosion Resistance | Salt Spray Test | ≥ 48 hours without rust |
| Quietness | Rolling Noise Test | ≤ 45dB |
| Anti-Static | Resistance Test | 10^5 - 10^9 Ω |
Medical casters must comply with multiple international standards:
ISO 22883: Caster Durability Test Standard;
EN 12530: Safety Requirements for Casters for Medical Equipment;
RoHS Certification: Ensures material safety;
CE Certification: Complies with EU market access requirements.
Reliable caster suppliers should provide complete test reports and certification documents to ensure product suitability in the global market.
A good caster supplier should have an independent R&D team capable of customizing designs based on the needs of medical device manufacturers, such as high-load casters, anti-static casters, and silent casters.
Use environmentally friendly and non-toxic materials to meet hospital hygiene requirements;
Surface treatment should provide rust and corrosion resistance;
High-precision machining ensures smooth operation of the casters.
Choosing a caster supplier is more than just purchasing products; it's about long-term partnership:
Provide sample testing;
Support bulk customization;
Provide after-sales maintenance and replacement recommendations. If you're looking for a reliable medical caster supplier, please contact Giessen Caster Supplier:

With the development of the Internet of Things and intelligent technologies, future medical casters will be more than just mechanical components. They may also possess the following functions:
Smart Positioning: Tracking device location via RFID or Bluetooth;
Load Monitoring: Sensors monitor load conditions in real time to prevent overloading;
Automatic Braking: Remote locking enabled by intelligent control systems;
Environmentally Friendly Materials: Using biodegradable or recyclable materials, in line with the trend toward green healthcare.
Professional caster suppliers are already exploring the application of these new technologies and are gradually moving towards intelligent solutions.
Medical casters play a crucial role in mobile imaging equipment. They not only ensure the safety and flexibility of the equipment but also directly impact the efficiency and quality of medical operations. As the medical industry continues to evolve, the technical requirements for casters are also increasing. Choosing a reliable caster supplier means choosing a more efficient and safer medical equipment solution.
