The Bosch Rexroth LINEAR-SET LSAOE-A-50-DD (R103865020) is a high-quality linear motion system designed for precise and smooth movement in various applications. This particular set includes an aluminum housing that is lightweight yet robust, providing a stable platform for the super linear bushing A with self-alignment features. The bushing is secured by a grooved taper pin and is equipped with external seals, making it relubricatable and suitable for maintaining cleanliness in operation. With a shaft diameter designated as size V, the LINEAR-SET LSAOE-A-50-DD ensures compatibility with corresponding components for seamless integration into machinery. It boasts two integrated wiper seals on both sides to minimize frictional drags when not under radial load, which can vary depending on speed and lubrication conditions. The product has been tested to achieve total travel ranging from 10^4 m to 10^5 m without failure, highlighting its durability and reliability. This linear set can handle a dynamic load capacity (size E) and has a static load rating (size M), indicating its ability to withstand various operational stresses. The maximum permissible linear speed (vmax) suggests that speeds of up to 5 m/s are possible, although the service life may be reduced due to increased wear on plastic parts under such conditions. Designed for zero-clearance or preloaded guides, this model includes an adjusting screw for radial clearance adjustments. It comes clamped to the h shaft lower limit and set to zero-clearance right out of the box, ensuring optimal performance from the start. Its operating temperature range is considerable, allowing it to function effectively across various environments. Overall, the Bosch Rexroth LINEAR-SET LSAOE-A-50-DD provides users with a robust and versatile solution for their linear motion needs, combining durability with precision engineering. Its design caters to applications requiring high levels of accuracy and longevity in their motion control systems.

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).

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.
