The Bosch Rexroth LINEAR-SET LSAHE-H-50-DD (R170225020) is a high-precision linear motion system designed for heavy-duty applications that require reliable and precise linear movement. This linear set is crafted from aluminum, providing a robust yet lightweight solution for various linear motion needs. The set includes an aluminum precision housing that incorporates a super linear bushing H, known for its ability to compensate for misalignments of up to 0.3 feet, ensuring smooth and accurate operation even in demanding conditions. Equipped with integrated wiper seals on both sides, the LINEAR-SET LSAHE-H-50-DD ensures protection against contaminants, thereby extending the life of the system and reducing maintenance needs. These wiper seals also contribute to the frictional drags generated by the bushings when not under radial load, which are dependent on speed and lubrication conditions. The system's shaft diameter 'd' is specifically designed to work seamlessly with the included super LB H bushing, which can be secured firmly with bolts and offers relubrication capabilities for long-term performance. The outer diameter 'D' is tailored to fit standard applications while allowing maximum permissible linear speeds (vmax) and accommodating dynamic load capacities that vary based on size specifications provided. This linear guide type caters to a wide temperature range from -20°C to +80°C, making it suitable for different working environments. It has been engineered to handle maximum accelerations (amax), static load ratings (C), and breakaway forces efficiently. The radial clearance comes pre-clamped to the h6 shaft lower limit and set to zero-clearance, ensuring optimal performance from installation. Overall, this Bosch Rexroth product belongs to a sophisticated product group known for its durability, precision engineering, and adaptability in various industrial applications where accurate linear motion is critical. With its adjustable features and heavy-duty design, it meets the stringent requirements of users seeking top-tier components for their machinery or systems.

Load direction factors
The load ratings C and C0 apply for the load direction ρ = 0°. For all other load directions, the load ratings must be multiplied by the factors fr (dynamic load rating C) or fρ0 (static load rating C0).

Reduced load capacity with short stroke
In case of short stroke, the service life of the shaft is less than that of the super Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .
| 1) | fs = factor |
| 2) | s = movement path |
Reduced load capacity with high load
The load rating is reduced under high load F. The dynamic load rating must be multiplied by the load factor f.F .
| 1) | fF = load factor |
