CUSTOMIZED SOLUTIONS
In the modern medical industry, the mobility, stability, and durability of equipment are crucial to both efficiency and patient safety. Casters, as an essential component of medical equipment, not only impact the flexibility of the equipment but are also closely linked to noise control, antimicrobial properties, load capacity, and ergonomic design. As the medical industry evolves towards high efficiency, low noise, and user-friendly operation, higher requirements are placed on the design and performance of medical casters. This article provides an in-depth analysis of five key aspects: application, structure and materials, technical advantages, selection guidelines, and maintenance. Incorporating the latest industry trends, this article provides a reference for purchasing and wholesale.

Casters for hospital beds must simultaneously meet the three key requirements of high load capacity, smooth movement, and reliable braking. High-end hospital beds are often equipped with centralized brake systems, allowing medical staff to quickly lock or release all casters, improving work efficiency.
These include emergency carts, infusion carts, and surgical instrument tables. Casters for these types of equipment require high flexibility and quiet operation, as well as anti-tangling features to prevent medical wires or fabrics from becoming trapped in the wheel axles.
Such as ultrasound machines, CT operating tables, and X-ray equipment require casters that are vibration-free during movement to protect high-precision sensors and image quality.
Casters must be lightweight, easy to maneuver, and maneuverable in narrow corridors. They must also have a certain degree of anti-static properties to prevent damage to electronic components.
Table 1: Application Classification of Commonly Used Casters for Medical Equipment
| Application Equipment | Main Performance Requirements | Recommended Caster Types |
| Hospital Beds | High load capacity, stable braking | Medium to large central brake casters |
| Emergency Carts | High flexibility, low noise | Silent dual-wheel swivel casters |
| Surgical Instrument Tables | Anti-tangle, antibacterial | Anti-tangle, antibacterial polyurethane casters |
| Diagnostic Imaging Equipment | Smooth, vibration-free, anti-static | Anti-static high-precision ball bearing casters |
| Mobile Monitors | Lightweight, flexible, anti-static | Small, silent, anti-static casters |
Polyurethane (PU): Highly elastic, wear-resistant, and low-noise, it is a common choice for medical equipment casters.
Thermoplastic Rubber (TPR): Soft material with excellent quietness and a low scratch resistance.
Nylon (PA): Lightweight, high load capacity, suitable for heavy medical equipment.
Medical casters often use precision ball bearings to reduce rolling resistance and extend service life. High-end models use sealed stainless steel bearings to prevent liquid and dust ingress and facilitate sterilization.
Stainless steel bracket: Corrosion-resistant, suitable for medical environments with frequent disinfection.
Galvanized steel bracket: Cost-effective, suitable for cost-sensitive medical carts.
Common braking methods for medical casters include:
Single-wheel brake: Controls a single caster.
Dual-wheel brake: Simultaneously locks swivel and roll functions.
Central brake: Controls all casters with a single brake, suitable for beds and large equipment.
Hospitals have strict noise control requirements. High-quality medical casters made of highly elastic PU or TPR materials can effectively reduce rolling noise. Some high-end models also have built-in vibration damping mechanisms to reduce the impact of vibration on delicate instruments.
Medical casters are often equipped with anti-tangling covers to prevent bandages, wires, etc. from entering the wheel axle. Antibacterial materials effectively inhibit bacterial growth, meeting the hygienic requirements of medical environments.
Thickened stainless steel brackets and a corrosion-resistant surface treatment ensure stable performance even under long-term, intensive use.
Some electronic medical equipment requires anti-static treatment to prevent damage to delicate components. Anti-static casters utilize specially formulated materials to achieve electrical conductivity.
When selecting casters for medical equipment, consider the following aspects:
Load Capacity: Select the appropriate load rating based on the total weight of the equipment (including instruments, medications, etc.). A 20%-30% safety margin is generally recommended.
Floor Conditions: TPR or PU casters are suitable for smooth tile and epoxy floors; nylon or thickened PU casters are suitable for concrete floors.
Noise Requirements: Silent casters are preferred for quiet environments such as operating rooms and ICUs.
Hygiene and Disinfection Frequency: Stainless steel brackets and antibacterial casters are recommended for equipment that requires frequent cleaning and disinfection.
Table 2: Caster Selection Recommendations for Different Usage Environments
| Usage Environment | Recommended Materials | Bracket Type | Special Function Recommendations |
| Patient Room | PU/TPR | Stainless Steel | Silent, Centralized Braking |
| Operating Room | TPR/Anti-static PU | Stainless Steel | Anti-static, Antibacterial |
| Emergency Pathway | PU | Electroplated Steel | Anti-tangling, Quick Turning |
| Outdoor Use | Nylon/Thickened PU | Stainless Steel | High-Load, Corrosion-Resistant |
Regular Cleaning and Disinfection: Medical equipment must maintain high hygiene standards. Casters should be regularly wiped with alcohol or medical-grade disinfectant.
Inspect the Wheel Surface and Bearings: Wheel Surface wear increases pushing resistance and should be replaced promptly. Bearings that produce unusual noises should be cleaned or replaced.
Brake Function Test: A weak brake can create a risk of equipment slippage. Regular brake reliability testing is required.
Lubrication and Anti-corrosion: Brackets and bearings are prone to rust in humid environments or those with high levels of disinfectants. Regularly apply anti-rust lubricant.
With the rise of smart healthcare and green, environmentally friendly materials, medical casters are poised for the following future developments:
Intelligent casters: Equipped with sensors to monitor the movement of equipment.
Environmentally friendly, antibacterial materials: Reduce the use of chemical disinfectants.
Lightweight designs: Reduce physical exertion for medical staff.
