NHK Spring supports the society

Yokohama Kiko Co., Ltd., a member of the NHK Spring Group, contributed to verifying the technology used in the asteroid explorer "Hayabusa".
By coating the inner surface of the sampling device with high-purity aluminum using Yokohama Kiko's technology, this served to prevent collected materials from mixing with other materials that could interfere with the analysis.

Our group company Nippon Shaft produces lightweight golf shafts, mainly under the N.S.PRO brand. Nippon Shaft's products are cherished by many customers, from professional players to beginners, all around the world.

These are special springs that control the magnetic data read/write position on the disks inside HDDs. Demand for high-capacity HDDs is increasing due to the growth of social networking and video distribution services. A single high-capacity HDD uses a large number of suspensions.

Used in HDDs, these parts include case covers and assembly parts, all of which are produced using high-precision press working technology.

Heater to increase wafer temperature

We manufacture and sell contact probes and related products used for testing electrical characteristics of semiconductor wafers and packages as Microcontactors🄬.

These remote control units, endowed with light operability and high reliability, allow users to maneuver vessels with confidence.

Spring-type tension balancers maintain a constant level of tension in overhead wires that supply power to railroad pantographs.

The turnouts manufactured by our group company Sumihatsu are used to safely change the direction of travel of railcars.

Motor cores are the core components of drive motors for EVs and HEVs. Rotating with the force of magnets, they generate the power that drives electric vehicles. These are products that require high-precision press working techniques due to strict dimensional tolerances relative to the size of the product.

Leaf springs are used to precisely hold down parts. Used in power control units for EVs and HEVs, they press heat-generating components against a cooler to improve cooling efficiency and so on. Our product lineup includes tapered leaf springs and grid springs.

Grid springs, which generate uniform in-plane loads

These springs absorb engine vibrations in a car's transmission with lock-up damper or HEV damper.

These are seats that support and protect the occupants of a vehicle and provide superior safety and comfort. We produce complete seats and the seat frames that constitute the framework for these seats.

Seats for Car Sickness Mitigation (Development Product)

Our automotive suspension springs contribute to the riding comfort and safety of drivers and passengers.

Coil Springs

Stabilizers

These products are used for LED headlights, power control units, instrument panels, chargers, etc. Characterized by high heat dissipating properties, they are increasingly attracting attention due to the electrification of cars.

Manufacturing methods for thin leaf springs are finely divided according to material, shape, and required strength. Products are made using various materials, such as carbon alloys, stainless steel, and copper alloys.

Disc Springs for Transmission

Our group company Topura manufactures screws for use in various products such as automobiles, home appliances, and ships. Its products include small 3mm screws, tapping screws, bolts of sizes exceeding 16mm, and resin-integrated molded bolts.

These label stickers serve as a tool for distinguishing between real and fake products. They have been adopted by many major domestic and international manufacturers of home appliances, computer supplies, automotive parts, clothing, and other products to protect their brands.

Our group company NHK Parking Systems sells and maintains mechanical multi-story parking systems. By equipping existing parking systems with EV battery recharging pallets developed by Yourstand Co., Ltd., we support EV users.
