The Bosch Rexroth LINEAR-SET LSGO-B-25-DD (R106782540) is a high-precision linear motion set designed to provide reliable and accurate linear guidance. This product features a steel linear set in an open configuration, which includes a shaft diameter of 'd' and is equipped with two integrated wiper seals, ensuring the system remains clean and free from contaminants. The precision housing is made from spheroidal graphite cast iron, and it includes a steel super linear bushing B without a self-alignment feature. This particular model is secured with a locating screw. The LINEAR-SET LSGO-B-25-DD boasts standard precision with its non-self-aligning super B series bushing, providing consistent performance with minimal friction force under no radial load conditions. The dynamic load capacity C indicates the set's ability to handle loads in the main direction of application, while the static load rating C0 reflects its capacity to withstand static forces. Designed for long guides that require shaft support and high rigidity, this linear set can accommodate maximum accelerations (amax) and operate within an ambient temperature range of -20°C to +80°C. It has an outer diameter D specified for the model, along with breakaway force details crucial for initial movements. The maximum permissible linear speed (vmax) suggests that speeds up to 5 m/s are possible; however, service life may be limited due to increased wear on plastic parts at higher velocities. With its robust construction and comprehensive specifications such as weight and size details provided for various components like size V, E, H, SW, L, etc., this Bosch Rexroth Linear Set is tailored for applications demanding precise linear movement coupled with durability and long service life. The product group ID helps in identifying the specific category of this component within the vast array of Bosch Rexroth's offerings dedicated to advanced motion solutions.

Impact of load direction on load rating of open Linear Bushings
The load ratings C and C0 apply for the main direction of loading ρ = 0°. For all other load directions, the load ratings must be multiplied by the factors fρ (dynamic load rating C) or fρ0 (static load rating C0).
Installing specific Linear Bushings can prevent reductions in load capacity (see Linear Set with side opening).
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 .

Radial clearance
The radial clearance values shown in the table have been determined from statistics and correspond to values expected in practice. The adjustable Linear Sets come clamped to an h5 shaft (lower limit) and set to zero clearance.
Vertical dimension
The tolerance values for the vertical dimension "H" for the Linear Sets shown in the table have been determined from statistics and correspond to values expected in practice.
Bolts
We recommend bolts in accordance with ISO 4762-8.8 for fastening the Linear Sets.
Lubrication
On-shaft relubrication on relubricatable Linear Bushing only until lubricant seeps out.
