The Bosch Rexroth LINEAR-SET LSK-25-DD-NR (R106022520) is a comprehensive linear motion system designed for smooth and precise linear movement applications. This linear set is crafted from durable plastic and features a rust-resistant pillow block housing made of reinforced polyamide (PA), ensuring a robust and corrosion-free performance. The set includes a segmental linear bushing that offers lightweight, stable, and cost-effective solutions for various linear motion requirements. The LINEAR-SET LSK-25-DD-NR comes equipped with two interchangeable wiper seals that provide additional protection against contaminants, contributing to the longevity of the system. Its radial clearance is adjustable, allowing for customization according to specific application needs, and it arrives clamped to the shaft with zero-clearance to minimize setup time. This model's dynamic load capacity indicates minimal values due to variable loading orientations and directions. It has been engineered for optimal performance within a permissible ambient temperature range, ensuring reliability across different working environments. The maximum acceleration and permissible linear speeds are specified to cater to a variety of operational demands. Additionally, the Bosch Rexroth LINEAR-SET features a stainless steel bolt, washer, and nut for secure mounting and maintenance ease. The friction force mentioned in the product specifications refers to the frictional drag generated by the linear bushings with integrated wiper seals when not under radial load; this force will vary based on speed and lubrication conditions. Overall, this linear guide type—comprising of a linear bushing and shaft—is an ideal choice for those seeking an efficient and adaptable solution for their linear motion systems. Its closed format of linear bushings ensures protection from external elements while maintaining consistent movement. With its lightweight design and static load rating considerations, this product is suited for various applications where precision linear guidance is essential.

Effect of load direction on load rating
The listed load ratings should be chosen depending on installation in minimum or maximum position and should be based on the calculations. If the load direction is clearly defined and the Linear Bushings can be installed in maximum position, the load ratings Cmax. (dynamic load rating) and C0 max (static load rating) can be used. If aligned installation is not possible or the load direction is not defined, the minimum load ratings must be used.
Reduced load capacity with short stroke
In case of a short stroke, the service life of the shaft is less than that of the segmental Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .
