Lightweight and high strength. Stays stable when rotated. A brush cutter that doesn't tire you out even after long hours of use...
With years of experience and unique technology, we provide high-quality and competitively priced products. Thanks to your understanding and support of Suehiro quality, our drive shafts for brush cutters hold a top-class market share of 90% domestically and 30% globally. In terms of specifications, we achieve straightness of 0.05/1000 or less, roundness tolerance of less than 1/3 of the outer diameter tolerance, and concentricity of 0.02 or less. This excellent finish allows us to produce drive shafts that do not wobble when rotated. Therefore, brush cutters equipped with our drive shafts are reputed to have low vibration and to be less tiring for long-term use. We have also contributed to the health of brush cutter users by preventing vibration-related diseases such as vibration white finger. Specifications: 【Compatible Steel Types】Special high-strength materials S48C/STKM17C/SWRH62B 【Compatible Dimensions】Outer diameter φ5.5 to φ11 Total length 100mm to 2500mm (customizable upon request)

basic information
Four Key Technologies Supporting Suehiro Products 1) Material Technology: We use custom materials that combine carbon with special elements. After heat treatment, an ideal high-strength shaft with both hardness and toughness is produced. 2) Straight Cutting and Straightening Technology: Steel inherently has a tendency to bend, but our unique technology applies heat treatment at 250 degrees of friction heat to achieve straightness with a precision of 0.05/1000 or less. Even after cutting and processing, the steel maintains its straightness and returns to its original shape when bent. 3) Cutting Technology: We perform cutting processing on both ends of the shaft. Although this takes more time and effort compared to forging with molds, the precision of the tooth profile is outstanding (concentricity of 0.02 or less)! The precise tooth profile created through cutting processing meshes well with the counterpart gear, reducing vibration. 4) Centerless Cutting Technology: All of our shafts undergo outer diameter grinding. By maintaining uniform roundness (1/3 of the outer diameter tolerance) and surface roughness, we stabilize the surface pressure with guide bushes and liners, reducing dynamic friction resistance and alleviating rotational resistance, thereby contributing to the engine's transmission capability.
