The Bosch Rexroth LINEAR-SET LSG-B-12-DD (R106581240) is a high-quality linear motion set designed for precision applications. This set includes a closed linear bushing of the Super B series without a self-alignment feature, ensuring stable and accurate movement. The product is crafted from durable steel with an outer diameter D and features an integrated wiper seal on both sides to protect against contaminants while maintaining low frictional drags, which are dependent on speed and lubrication conditions. The LINEAR-SET LSG-B-12-DD boasts a standard precision housing made from lamellar graphite cast ironsteel, providing robust support for the super linear bushing B. It has been engineered for fixed working bore diameters with shaft diameter d, suitable for various industrial applications where precision is key. The set operates efficiently within a permissible ambient temperature range of -20°C to 80°C, accommodating a wide range of operating environments. Dynamic load capacity C and static load rating C are indicative of the product's ability to withstand forces during operation. These capacities are given for the main direction of loading; however, they must be adjusted by specific factors if the direction of loading varies. The LINEAR-SET can handle maximum accelerations (amax) gracefully and is capable of achieving a breakaway force of 0.5 N without radial load. This Bosch Rexroth linear set is designed with size E dimensions, and it weighs 0.3 kg, making it suitable for various installation spaces while ensuring ease of integration into machinery or equipment setups. The product group ID further classifies it as part of Bosch Rexroth's comprehensive offerings in linear motion technology. Overall, the LINEAR-SET LSG-B-12-DD is tailored for users requiring precise linear guidance systems that combine durability with performance in demanding industrial settings or sophisticated mechanical assemblies.

Impact of load direction on load rating of closed Linear Bushings

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 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 .

Life expectancy calculation

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.
