They are motion parts which we provide with confidence and trust. The Oil Free Bushings is superior in sliding and lubricity under the condition of Oil Free and maintenance free. The parallel key lets rotary shafts and gears or belt pulleys fix and rotate together. The standard rack changes rotary motion to linear motion. We deal with large assortment of mechanical parts.

Oil Free Bushings

The Oil Free Bushings is metal based bearing which used high strength brass casting （HBｓC3C）and solid lubricant. It is suitable for environments such as the place, where oil supply is difficult structurally, maintenance is impossible. The Oil Free Bushings is superior in sliding and lubricity under the condition of Oil Free and maintenance free.

Machine key

The machine key fixes the gear and belt to the rotating shaft, and enables them to rotate together. With using a high-precision and high-quality machine key, reliable machine designing will be possible. YSK is the shaft kingdom. That’s why we can provide the machine key which is the best match for the shaft."

Standard rack

Linear gear rack is necessary part for changing rotary motion of small gear pinion to linear motion. We provide guarantee of precision and cost merit using annealing S45C as material."
