The Bosch Rexroth LINEAR-SET LSRE-80-DD (R107628020) is a high-quality linear motion system designed to offer precision and durability in various applications. This linear set is constructed from steel and includes a standard precision housing steel radial linear bushing, which ensures reliable performance under dynamic load conditions. The LSRE-80-DD model features two wiper seals to protect against contamination and is relubricatable for easy maintenance. With a shaft diameter of 'd,' the linear set provides an adjustable radial clearance, allowing for zero-clearance settings before delivery to ensure precise motion control. The open design of the bushing allows for adjustments and servicing without disassembly, enhancing the ease of use in complex setups. The product operates efficiently within a permissible ambient temperature range of 'C ... C,' ensuring stability across different working environments. Its dynamic load capacity 'C' and static load rating 'C' are indicative of its capability to handle significant loads, primarily in the main direction of loading. Additionally, it can withstand maximum accelerations up to 'amax' without compromising its structural integrity. This model boasts an outer diameter 'D,' which facilitates compatibility with various machine designs. It has a defined breakaway force and can achieve a maximum permissible linear speed 'vmax,' making it suitable for high-speed applications. The Bosch Rexroth LINEAR-SET LSRE-80-DD is ideal for creating heavy-duty guides when paired with precision steel shafts and shaft support rails, resulting in an assembly with exceptional rigidity. This makes it suitable for industrial applications requiring precise linear movement, such as automation systems, CNC machines, and other sophisticated mechanical setups. The weight specification further contributes to its suitability for robust applications where both mass and momentum play critical roles in design considerations.

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.
