CUSTOMIZED SOLUTIONS
Medical equipment casters are essential moving components for various equipment in hospitals, clinics, and laboratories. Their performance directly impacts the safety and ease of use of these equipment. Effectively extending the service life of medical equipment casters not only reduces maintenance costs but also ensures smooth operation in the medical environment. This article will provide an in-depth analysis of key technologies and practical methods for extending the service life of medical equipment casters, covering various aspects including caster material selection, installation and maintenance, environmental adaptability, and regular maintenance.
Medical equipment casters are primarily responsible for the smooth movement and positioning of equipment, providing multiple functions such as load-bearing, shock absorption, anti-slip properties, and quiet operation. High-quality casters ensure safe and rapid movement of equipment within medical settings, preventing damage to the floor and the equipment itself.
Medical environments typically have the following characteristics:
High cleanliness requirements to prevent bacterial growth
Frequent disinfection, requiring casters with high corrosion resistance
Frequent equipment movement, requiring high load-bearing and wear resistance
Requires silent operation to avoid disturbing patients' rest
Mobile monitors, ventilators
Operating tables and surgical instrument carts
Hospital beds and nursing carts
Laboratory equipment carts
Common materials for medical casters include polyurethane (PU), thermoplastic rubber (TPR), nylon, and aluminum alloy.
| Material | Advantages | Disadvantages | Applicable Environments |
| Polyurethane (PU) | Wear-resistant, quiet, non-slip, and good floor protection | Highly expensive | Suitable for operating rooms, hospital wards, and general medical equipment |
| Thermoplastic Rubber (TPR) | Quiet, soft, and corrosion-resistant | Low load-bearing capacity | Suitable for lightweight equipment |
| Nylon | High strength, good load-bearing capacity, and chemical resistance | High floor abrasion and noise | Suitable for warehouses and heavy equipment |
| Aluminum Alloy | Lightweight and corrosion-resistant | High cost and poor flexibility | Suitable for special environments such as high humidity and highly corrosive areas |
Bearings are the core load-bearing and rotating components of casters. Commonly used bearings include ball bearings and plain bearings. Ball bearings offer flexible rotation and long life, making them suitable for the frequent movement of medical equipment.
Bearing Type; Advantages; Disadvantages
Ball bearings: Low friction, wear resistance, and flexible rotation; Highly expensive
Sliding bearings: Simple structure and low price; High friction and short service life
Casters for medical equipment must be selected according to the load rating of the equipment to avoid overloading that could damage or deform the bearings. It is generally recommended that a safety margin of 20%-30% be left over the rated load capacity of casters.
A larger wheel diameter makes it easier to navigate obstacles and reduces rolling resistance. Wheel width affects load distribution and ground contact area. Choosing the right wheel width helps reduce ground wear and improve stability.
Check the caster model and load capacity before installation.
Ensure the mounting surface is flat to avoid uneven loads caused by uneven installation.
Appropriate fasteners should be used for caster installation. Avoid overtightening, which may damage the bearings, or over-tightening, which may cause looseness and damage.
Ensure that the equipment's center of gravity is evenly distributed across all casters to avoid overloading individual casters and extend overall service life.
Install dust covers and seals to prevent dust and liquid from entering the bearings, reducing wear and corrosion.
Regularly lubricate bearings to reduce friction; severely worn parts should be replaced promptly to prevent cascading damage.
Disinfectants commonly used in hospitals and high humidity levels can easily corrode metal components. Choosing corrosion-resistant materials or surface coatings is particularly critical.
Frequent use of disinfectants can damage the caster surface and bearings. Choose chemical-resistant materials and use non-aggressive cleaning agents.
Extreme temperatures can cause caster materials to become brittle or deform. Choose materials that maintain stable performance within the appropriate temperature range.
| Inspection Items | Inspection Content | Recommended Cycle |
| Wheel wear | Observe the tire for cracks and nicks | Monthly |
| Bearing rotation | Manually rotate to check for smoothness | Monthly |
| Fastener looseness | Check mounting bolts for looseness | Quarterly |
| Dust cover and seal condition | Check for damage | Quarterly |
Clean the wheel surface and bearings to remove dust and dirt
Apply grease to ensure smooth bearing rotation
Replace damaged parts to maintain overall performance
Record a maintenance log to track caster condition
Use specialized caster lubricant for enhanced protection
Avoid rapid movements and sharp turns to reduce wear
Configure thicker wheels and high-load bearings for high-load equipment
