en.Wedoany.com Reported - KHK USA Inc. has launched a series of ground helical racks (KRHG, KRHGF, KRHGFD), designed for precision motion systems to achieve smooth operation, high torque transmission, and lasting performance.

These ground helical racks are suitable for demanding environments requiring precision and low-noise operation, such as machine tools, high-speed automation equipment, and precision positioning systems. Manufactured from SCM440 alloy steel and subjected to quenching, tempering, and induction hardening, they offer excellent strength, rigidity, and wear resistance. Precision grinding achieves JIS N6 grade (KHK Class 1), ensuring each rack meets strict accuracy requirements.

The series offers modules M1 to M6 and standard lengths of 100, 500, and 1000 mm, accommodating various system configurations. It includes three models: the KRHG model for standard applications; the KRHGF model with machined ends for easy connection and alignment; and the KRHGFD model with machined ends and bolt holes for seamless assembly. The ground helical racks are compatible with standard metric helical gear shafts, allowing engineers to build motion systems without delays from custom manufacturing. KHK USA, a wholly owned subsidiary of Kohara Gear Industry Co., Ltd., offers these products from stock.
