This linear set features an aluminum construction that is both lightweight and durable, providing a robust solution for various linear motion needs. The open, adjustable design allows for easy installation and maintenance, while the super LB A linear bushing ensures smooth and accurate movement. Equipped with two seals, the LINEAR-SET LSAOE-A-25-DD offers protection against contaminants, making it suitable for use in environments where cleanliness is paramount. The self-aligning feature of the super linear bushing A ensures optimal performance even under misaligned conditions, reducing wear and extending service life. The system is designed to accommodate a shaft diameter 'd' and comes with an external seal for additional protection. It is also relubricatable, which helps maintain performance over time. The standard version of this product includes a grooved taper pin for secure mounting. With its dynamic load capacity C and static load rating C tailored to the main direction of loading, this linear set can handle significant forces while maintaining high precision. It boasts impressive maximum acceleration amax and can operate within a wide range of ambient temperatures without compromising functionality. The outer diameter 'D' ensures compatibility with various applications, and the breakaway force specifications indicate its ability to overcome initial stiction. The LINEAR-SET LSAOE-A-25-DD can achieve maximum permissible linear speeds vmax, with potential speeds up to 5 m/s under certain conditions. This product has been tested extensively to ensure reliability over long travel distances without failure. It comes pre-clamped to h6 shaft lower limit and set to zero-clearance for immediate use without the need for further adjustments. Its weight makes it an efficient choice for systems where mass is a concern. Overall, the Bosch Rexroth LINEAR-SET LSAOE-A-25-DD (R103862520) stands out as an adaptable and precise solution for various linear motion requirements across multiple applications.

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.

	FR = Frictional drag
	s = travel distance
	v = travel speed

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.
