Powering Electric Vehicles with Rotor Clip   

The electric vehicle (EV) market is rapidly growing as the world moves toward more sustainable, eco-friendly transportation. At Rotor Clip, we’ve been proud to support the automotive industry through this transition, from traditional combustion engines to electric drivetrains powering today’s vehicles. For over 65 years, we’ve worked alongside manufacturers and suppliers around the globe, providing high-quality retaining rings, wave springs, and hose clamps that play a critical role in ensuring the performance, safety, and reliability of every vehicle. 

Electric vehicles demand parts that can handle extreme, high-performance environments while meeting strict safety and durability standards. That’s where Rotor Clip comes in. Our products are designed to secure connections, manage movement, reducing weight and reduce vibrations—all essential factors in keeping EV systems running smoothly. As the EV market continues to grow, we’re committed to evolving with it, continuously improving our solutions to meet the ever-expanding needs of the automotive industry. 

EVs rely on electric drivetrains powered by rechargeable batteries to provide a cleaner alternative to traditional combustion engines. The key components of an EV, including the battery, electric motor, and power electronics, work together to deliver energy, manage power flow, and drive the wheels. Rotor Clip’s retaining rings, wave springs, and hose clamps play a crucial role in ensuring the smooth operation of these systems. Trusted by manufacturers worldwide, our parts are designed to meet the highest standards for safety, reliability, and durability. Certified to IATF 16949, our engineering, metallurgical, and quality assurance teams meticulously oversee every step of production to ensure the quality you expect. 

With our vertical integration, we manage every critical production step in-house, ensuring precise quality control, optimized processes, and continuous innovation. Our team specializes in providing custom solutions tailored to your electric vehicle (EV) applications. If one of our 20,000+ standard parts doesn’t meet your specifications, our engineers will collaborate with you from prototype to production, offering modifications such as adjustments to section and thickness, diameters, load and rotational capacity, materials, and more. Whatever your requirements, we’re committed to delivering the exact parts you need, when you need them. 

Rotor Clip Parts and Their Functions 

• Retaining Rings:  

Rotor Clip is proud to be the only manufacturer of every style of retaining ring (tapered section/ circlips, constant section/ snap rings, spiral rings), setting us apart from the competition. Our rings are available in global standards including Inch, DIN, ANSI metric, and JIS. Retaining rings offer a reliable and cost-effective alternative to cotter pins and bolts, with minimal surface preparation and reduced mass. Ideal for a range of thrust loads, our rings can prevent unwanted movement, secure assemblies, ensuring precise alignment and take-up endplay in a range of automotive applications. 

• Wave Springs:  

Rotor Clip Wave Springs (multi-turn, single-turn, nested, round-wire, linear) are designed for applications where space is limited, but high load-bearing capacity is critical—making them ideal for EV systems. By generating force through bending rather than torsion, these springs save both axial and radial space compared to traditional coil springs, addressing complex automotive challenges while ensuring smooth operation, reduced wear, and extended vehicle lifespan. Smaller spring cavities reduce assembly sizes and offer the added benefit of weight savings, which is essential for improved performance. 

If your application requires exceptional resistance to torsional loads and high acceleration, ask about our new patented InterShim™ wave spring. 

• Hose Clamps: 

Rotor Clip Hose Clamps (constant tension band, wire) securely fasten hoses carrying fluids like coolant and battery coolant in electric vehicles. Our self-compensating clamps expand and contract with temperature changes, eliminating the need for manual adjustments and preventing over- or under-tightening. Designed for efficient pneumatic and manual installation, they reduce assembly time, lower costs, and improve production efficiency—all while meeting high-quality standards like IATF 16949 certification. 

From Design to Application 

1. EV Motor: Internal Retaining rings/ Snap rings are used to retain shaft bearings in the motor housing. Multi-Turn wave springs are used to preload bearings and reduce high speed vibration. 
2. Battery Packs: Push-On retaining rings are used to secure module to module connections between battery packs. 
3. Cooling Fans: Patented flat end Single-Turn wave springs are being used to preload the fan bearings and extend bearing life. 
4. Coolant Overflow Reservoir: Constant-tension band clamps are used to secure low pressure overflow hoses from the radiator to the overflow reservoir. 
5. Quick Connects: Used in the high-pressure battery pack cooling system, the quick connect fittings utilize internal snap rings to retain a Single-Turn wave spring and a shim end Rotor Clip Multi-Turn wave spring in the internal quick connect and valve assemblies. 

Rotor Clip parts power more than just electric vehicles—they support the full range of e-mobility applications and are ready for whatever advancements come next. From e-bikes and e-scooters to electric boats, aircraft, and the next generation of electric transportation, our precision-engineered parts ensure safety and reliability in every part of your build. As industries shift toward greener, more sustainable solutions, Rotor Clip is committed to providing solutions that support today’s electrification efforts and tomorrow’s innovations.
