The Bosch Rexroth LINEAR-SET LSAHE-SH-25-DD (R170242520) is a high-quality linear motion set designed for precise and heavy-duty applications. This linear set features a lightweight precision aluminum housing and super linear bushings SH, which are capable of compensating for misalignments up to a specified tolerance, ensuring smooth and accurate motion. The shaft diameter is designed to fit specific requirements, enhancing the system's versatility. Equipped with integrated wiper seals on both sides, the LINEAR-SET LSAHE-SH-25-DD ensures that contaminants are kept out, thereby extending the lifespan of the system while maintaining its performance. These wiper seals also contribute to the frictional force under no radial load conditions. The product is relubricatable, which allows for easy maintenance and longevity of the set. With a dynamic load capacity that applies predominantly in the main direction of loading, this linear set can handle significant forces during operation. It also boasts a high maximum permissible linear speed and can operate within a wide temperature range, making it suitable for various working environments. The outer diameter and breakaway force specifications cater to size H requirements, while the static load rating aligns with size M standards. This product comes clamped to an h shaft at the lower limit and is pre-set to zero-clearance to minimize installation time and effort. Overall, the Bosch Rexroth LINEAR-SET LSAHE-SH-25-DD offers reliability and precision for applications requiring robust linear motion solutions. With its adjustable heavy-duty design and ability to withstand challenging conditions while maintaining performance integrity, it stands as an ideal choice for sophisticated mechanical 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 |
