The Bosch Rexroth SOLID SHAFT (R100004061) is a precision-engineered component designed for linear motion applications. This solid shaft is crafted from heat-treated steel and features a hard chrome plating on the outer diameter, ensuring optimal surface corrosion protection and enhanced durability. With a shaft diameter tolerance classified as h6, it provides a precise fit for linear bushings, allowing for smooth movement within mechanical systems. The chrome plating thickness of approximately 20 µm not only contributes to the shaft's hardness, which is rated at a minimum of 670 HV, but also enhances its wear resistance. The maximum usable length (Lmax) of the shaft can be extended by combining sections, facilitating longer overall lengths without compromising performance. This feature enables linear bushings to roll over joints seamlessly. The material's mass is specified at 2.57 kg/m, indicating its robustness and suitability for heavy-duty applications. The precision steel shaft adheres to stringent standards of geometry and hardness with a hardness minimum of 58 HRC and a cylindricity tolerance of IT3/2µm, ensuring uniformity in shape and size across its length. Surface roughness is maintained at RA 0.3 µm or less, which minimizes friction and wear when interacting with other components. The depth of hardness extends to at least 0.5mm beneath the surface, providing substantial protection against deformation under load. Straightness is another critical factor in the shaft's design; it maintains a straightness tolerance as per ISO standards with the smallest possible value being ≤0.2 mm for lengths under 1 m. This ensures that the shaft remains true along its length, contributing to accurate and reliable linear motion within the system it is integrated into. Overall, the Bosch Rexroth SOLID SHAFT (R100004061) represents an ideal solution for applications requiring high-precision linear guidance with exceptional surface protection against corrosion and wear.
