The Bosch Rexroth LINEAR-SET LSAHO-SH-20-VD (R170342070) is a high-quality linear motion set designed for precise and heavy-duty applications. This fully sealed linear set is constructed with lightweight precision aluminum housing and incorporates super linear bushings SH, which are capable of compensating for misalignments up to a specified tolerance. The shaft diameter 'd' ensures robust performance, while the standard version's design facilitates ease of maintenance with its relubricatable feature. This LINEAR-SET is particularly noted for its ability to handle dynamic loads efficiently, as indicated by the dynamic load capacity 'C', which applies to the main direction of loading. The product also boasts an impressive maximum acceleration 'amax' and can operate within a wide range of ambient temperatures, from minimum to maximum degrees Celsius without compromising on performance. The outer diameter 'D' is tailored to size 'H', ensuring compatibility with various applications. Furthermore, the LINEAR-SET has been engineered to withstand significant static loads with its substantial static load rating 'C'. The breakaway force and maximum permissible linear speed 'vmax' are indicative of the unit's capability to operate smoothly under varied operational conditions. This product falls under Productgroup ID that pertains to linear sets equipped with linear bushings. The format of these bushings is HO – Heavyduty, open – signifying their durability and suitability for open configurations. Additionally, this model has been secured with bolts and offers low frictional drags generated by integrated wiper seals when not under radial load, as reflected in the footnote regarding friction force 'FR'. Weighing in at just . kilograms, this Bosch Rexroth Linear Set combines lightweight construction with robust performance features, making it an ideal solution for those seeking reliable linear motion components that are both efficient and durable.

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 .

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 .
