The Bosch Rexroth LINEAR-SET LSGE-A-50-DD (R106665040) is an advanced linear motion set designed for precision applications. This linear set is composed of high-quality steel with a standard precision housing made from lamellar graphite cast iron and features a super linear bushing A with a self-alignment characteristic. The integrated wiper seals on both sides ensure the cleanliness of the system, thus prolonging its service life and maintaining its efficiency. With a shaft diameter of 50 mm, the LINEAR-SET LSGE-A-50-DD has been engineered to provide adjustable radial clearance, which comes clamped to the lower limit of the h shaft and set to zero-clearance for high precision requirements. The dynamic load capacity C, as well as static load rating C, indicate this linear set's ability to handle significant loads in its main direction. In cases where loading direction varies, specific factors are provided to calculate adjusted load capacities. The unit can withstand maximum accelerations (amax) and operates effectively within a permissible ambient temperature range from -20°C to 80°C. It boasts an outer diameter D that complements its robust design while maintaining a breakaway force that ensures stability under initial movement. The maximum permissible linear speed (vmax) indicates that speeds up to 5 m/s are possible; however, it's important to note that at these speeds, service life may be reduced due to increased wear on plastic components. This product is particularly suitable for applications requiring precise guidance and smooth motion with minimal frictional drag when not under radial load. Its design allows for considerable travel distances without failure, demonstrating Bosch Rexroth's commitment to durability and performance in their linear motion products. The LINEAR-SET LSGE-A-50-DD is also notable for its ease of maintenance due to features like adjustable radial clearance and integrated wiper seals. Overall, the Bosch Rexroth LINEAR-SET LSGE-A-50-DD is an exemplary solution for those seeking reliable and precise linear motion control in their mechanical systems or machinery setups.

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 .

1) fs = factor
2) s = movement path

Reduced load capacity with high load

If the load F on a Super Linear Bushing A is more than F > 0.5 x C, the dynamic load rating C decreases.

Definition of dynamic load ratings

Self-alignment feature

The self-alignment feature in the steel bearing plates and machined ball guide grooves ensure quieter travel. The flow chart shows a comparison with a conventional Linear Bushing. The example is based on a load of 800 N and misalignment of about 8 ft (caused by shaft deflection).

Due to the self-alignment feature, two super Linear Bushings must be used on at least one of the shafts in the guide.

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.
