The Bosch Rexroth LINEAR-SET LSSO-B-12-DD (R106781240) is a high-precision linear motion set designed for applications that require accurate and smooth linear movement. This set comprises a standard precision housing made from spheroidal graphite cast iron and a steel super linear bushing B, which lacks self-alignment features. It includes integrated wiper seals to protect against contaminants and is secured with a locating screw. The shaft diameter is designated as size V, while the bushing size is B, and it is part of the Series Super B with no self-alignment feature. The product also notes friction force FR, indicating the frictional drags that are generated by the linear bushings when they are not under radial load. These drags vary based on speed and lubrication conditions. The LINEAR-SET LSSO-B-12-DD boasts a dynamic load capacity C, which applies to the main direction of loading, ensuring it can handle significant forces during operation. It also has a static load rating C for stationary applications or when movements are minimal. Designed for long guides that require shaft support along with high rigidity, this linear set can accommodate maximum acceleration (amax) and can be used within an ambient temperature range of -20°C to +80°C. The outer diameter D and breakaway force are specified for precise engineering requirements. With a weight of 0.7 kg, this linear guide type ensures reliability in various applications. The maximum permissible linear speed (vmax) suggests speeds of up to 5 m/s are possible; however, service life may be limited due to increased wear on plastic parts under such conditions. Tests have demonstrated total travel ranging from 100 km to 10^4 km without failure. In summary, the Bosch Rexroth LINEAR-SET LSSO-B-12-DD provides robust performance for systems requiring durable and precise linear motion capabilities within specified environmental and operational parameters.

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 .

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.
