The Bosch Rexroth LINEAR-SET LSRSE-50-DD (R107825020) is a high-precision linear motion component designed for a variety of applications requiring precise and smooth linear movement. This linear set is composed of a standard precision housing with a side opening and an adjustable steel radial linear bushing equipped with two wiper seals, ensuring protection against contaminants and the ability to be relubricated for extended service life. The shaft diameter 'd' is specifically engineered to accommodate the accompanying bushing, providing an optimal fit. This model boasts a robust design capable of withstanding dynamic load capacities in the main direction of loading, indicated by the arrow direction FsubHsub or FsubHsub. It features a maximum acceleration (amax) and can operate within a permissible ambient temperature range, ensuring reliability even in fluctuating environmental conditions. The outer diameter 'D' and size 'SW' are meticulously crafted to meet precise specifications, while the breakaway force and maximum permissible linear speed (vmax) are indicative of its capability to handle high-speed applications. The LINEAR-SET LSRSE-50-DD also has an impressive static load rating (C), which, along with the dynamic load capacity, applies when loaded in the main direction. The friction force is minimized due to its design, and radial clearance is carefully controlled; it comes with an 'h' shaft lower limit and is set to zero-clearance before delivery for immediate installation without the need for further adjustments. This product falls under the product group ID that specifies its classification as a linear guide type with linear bushing and shaft. Its format is categorized as SE – with side opening, adjustable – which allows for significant versatility in application. However, it's important to note that there may be a reduction in load capacity when open Linear Bushings are loaded counter to the direction of opening. The weight specification underscores its solid yet manageable build quality suitable for various industrial applications where precision linear motion is critical.

Definition of dynamic load ratings
Rigidity
Combining a radial Linear Bushing with a continuously supported guide shaft ensures a precise, rigid design.
The following figure shows load-dependent spring. The diagram applies for installation: Without preload With zero clearance (no preload) for load direction ρ = 0° – 90° and 270° – 360°Radial Linear Bushing rigidity
Installing with preload reduces spring. Additional spring in all parts of a linear guide (housing, shaft, shaft support rail) depends on the load direction. Guideline values for total spring with R1076 and R1010 elements: load direction factor multiplied by spring ∂ (from right diagram).

Effect of load direction on load rating
The load ratings C and C0 specified for Radial Linear Bushings apply for load direction ρ = 0°. If the external load is at an angle ρ = 90° – 270°, a reduced load capacity must be factored in. The dynamic load rating is then determined by multiplying the specified dynamic load rating C or C0 by the load direction factors fρ or fρ0. This reduced load capacity can be avoided by careful installation of the radial Linear Bushings.
