How to Choose the Best Casters for Cleanrooms
Choosing the right casters for cleanrooms is critical to maintaining the cleanliness, safety, and efficiency of your operations. Whether you're in aerospace engineering, electronics manufacturing, pharmaceuticals, or any other industry that uses cleanrooms, the casters you choose must meet strict contamination control standards while ensuring the safe movement of sensitive equipment.
In this guide, we’ll walk through the key factors to consider when selecting casters for cleanrooms and provide recommendations for different types of cleanrooms across industries.
Why Choosing the Right Casters Matters
Cleanrooms are designed to minimize contamination by controlling the air quality, temperature, and humidity. Casters used in these environments must:
- Resist particle shedding to prevent contamination.
- Be easy to clean and sanitize to meet industry hygiene standards.
- Protect sensitive flooring while allowing smooth, safe movement.
- Prevent static buildup for environments that handle sensitive electronics or equipment.
Selecting the right caster depends on the specific type of cleanroom and its requirements. Below are the top considerations for different industries.
Casters for Aerospace & Defense Engineering Cleanrooms
Aerospace cleanrooms are critical for the assembly of precision components used in aircraft, spacecraft, and defense systems. These facilities require a high level of cleanliness to prevent contamination of sensitive parts and ensure the integrity of precision equipment.
Recommended Casters for Aerospace & Defense Cleanrooms
Stainless Steel Casters with ESD Protection
Aerospace cleanrooms often require casters that are both corrosion-resistant and ESD (Electrostatic Discharge) protected. Stainless steel casters with electrostatic dissipative polyurethane wheels like CC Apex ESD are ideal for preventing static buildup and ensuring smooth movement of sensitive tools and parts.

Key Considerations for Choosing Aerospace & Defense Cleanroom Casters
Vibration Control
Precision tools and components need vibration-free movement. Casters with spring-loaded mechanisms or soft-tread materials like polyurethane or rubber can dampen vibrations and ensure smooth transport.
Heavy Load Support
Casters for aerospace cleanrooms must handle the weight of large components such as engines, tooling carts, and work platforms without compromising the cleanroom's integrity.
Casters for Electronics Manufacturing Cleanrooms
Electronics manufacturing cleanrooms have stringent ESD (Electrostatic Discharge) control requirements due to the sensitivity of electronic components like semiconductors and circuit boards. Even a small amount of static can damage delicate electronics, making ESD control a top priority.

Electrostatic Dissipative Polyurethane Casters
These casters prevent static buildup while protecting sensitive flooring. Electrostatic dissipative polyurethane wheels like CC Apex ESD are ideal for electronics manufacturing environments and applications like server racks, due to their ability to dissipate static charges.
Electrically Conductive TPR Casters
Conductive thermoplastic rubber (TPR) casters provide efficient static grounding, ideal for electronics manufacturing environments that require reliable static control. These casters have a very low electrical resistance, allowing static charges to flow directly through the caster and into the ground. They quickly dissipate charges, making them ideal for environments with sensitive electronics where even minimal static buildup could cause damage. However, they require grounding to be effective, and they allow a continuous current path, which might not be suitable for some delicate components.

Key Considerations for Electronics Cleanroom Casters
ESD Compliance
Ensure all casters meet ESD standards to protect delicate components from damage.
Floor Protection
Non-marking casters are essential to avoid leaving tracks or damage on the cleanroom floor, which could create contaminants.
Casters for Pharmaceutical and Medical Device Cleanrooms
Pharmaceutical and medical device manufacturing cleanrooms have some of the strictest cleanliness requirements, as they handle products that must remain free of contamination. These environments require casters that are easy to clean, resistant to chemicals, and able to withstand frequent washdowns.
Recommended Casters for Pharmaceutical & Medical Device Cleanrooms
Stainless Steel Casters with Phenolic Wheels
Phenolic wheels can handle high temperatures and are resistant to chemicals, making them ideal for food processing environments. Paired with stainless steel forks, these casters ensure corrosion resistance and easy cleaning.
Rubber-Tread Casters
For environments with sensitive flooring or where noise reduction is important, rubber-tread casters offer smooth, non-marking movement.

Key Considerations for Pharmaceutical & Medical Device Cleanroom Casters
Frequent Washdowns
Casters must withstand exposure to water and cleaning agents while maintaining performance and cleanliness.
Non-Marking Materials
Non-marking wheels are important to prevent debris buildup and floor damage, both of which can introduce contaminants into the cleanroom.
Casters for Life Sciences & Biotech Cleanrooms
Cleanrooms in life sciences and biotech handle the production of sensitive biological materials and require the highest levels of contamination control. In these environments, casters must prevent particle shedding and be compatible with chemical cleaning processes.
Recommended Casters for Life Sciences & Biotech Cleanrooms
Polyurethane on Stainless Steel Casters
These casters provide a durable, non-marking solution that is resistant to chemicals. Polyurethane wheels are quiet and offer good floor protection, while the stainless steel components resist corrosion.

Key Considerations for Life Sciences & Biotech Cleanroom Casters
Outgassing
Choose casters made from non-outgassing materials to avoid introducing unwanted particles into the cleanroom environment.
Contamination Control
Ensure that all materials used in the casters are compatible with the cleanroom’s sanitation protocols and do not release particles into the environment.
Sealed Bearings
To prevent any debris from escaping into the cleanroom, sealed bearings are a must for casters in life sciences and biotech facilities.
Choosing the Right Casters for Your Cleanroom
Selecting the best casters for your cleanroom involves understanding the specific requirements of your industry and ensuring that the casters you choose meet strict contamination control standards. Whether you're working in aerospace engineering, electronics manufacturing, pharmaceuticals, or food production, the right casters can enhance the safety, cleanliness, and efficiency of your operations.
Consider factors such as ESD protection, non-marking materials, corrosion resistance, and vibration control when making your decision. With the right casters, your cleanroom will not only maintain its cleanliness standards but also improve the movement and handling of sensitive equipment.
