Smorley’s "Wave Spring / Retaining Ring" is manufactured using a unique edge winding process, achieving excellent strength and dimensional stability. 【Reasons to Choose This Product】 <Wave Spring> ■ Approximately 50% reduction in free length compared to coil springs, enabling miniaturization and lightweight design of products. ■ Equivalent force and deflection to coil springs. ■ Flexible design for diameter and number of coils. ■ Extensive catalog sizes available. <Retaining Ring> ■ Unique processing method reduces material waste compared to press processing (economically produces large diameter retaining rings). ■ No protrusions for attachment and detachment unique to C-type retaining rings, preventing interference with mating parts. ■ Flexible design possible with a 360° gap-free retaining surface. ■ Capable of high-speed rotation over 15,000 rpm. ■ Easy installation and removal without the need for special tools. ■ Extensive catalog sizes and design options for end shapes. Custom designs are available without mold costs for minimum inner diameters from 2.5mm to 3,000mm. For stock items, we provide free samples of required part numbers in small quantities. *For more details, please refer to the PDF document. Feel free to contact us with any inquiries. We are currently offering free sample bags (distribution will end once stock is depleted).

At SMALLEY, which has a long track record in retaining rings, we have developed a "self-locking mechanism" retaining ring suitable for high-speed applications such as EV motors. The new product "Revolox" prevents the ring from expanding due to centrifugal force during high-speed rotation by having protrusions in the slot area, ensuring the ring functions properly. Both the slot and protrusion areas have sufficient strength to prevent damage during installation and removal. 【Key Points for Choosing This Product】 ■ Can be considered as an alternative for high-speed shaft rotation that cannot be held by snap rings (please contact us for rotation speed inquiries) ■ The slot and protrusion areas have sufficient strength, preventing damage during installation and removal ■ Approximately 50% lighter than conventional rings, achieving efficiency in high-speed rotation by reducing rotational mass ■ Automatic installation processes can be considered for mass production ■ Minimal runout during rotation, making it suitable for vibration reduction If you are having trouble with existing snap rings, please contact us. Design changes and welding can be considered without incurring costs or time. *For product details, please contact us directly or refer to the brochure (English version).
