The Bosch Rexroth LINEAR-SET LSAOE-A-20-DD (R103862020) is a high-quality linear motion system designed for precision applications where smooth and accurate movement is required. This linear set features an aluminum housing that is both lightweight and sturdy, ensuring durability while minimizing additional weight to the system it's integrated into. The open, adjustable design allows for easy access and maintenance, making it a versatile choice for various applications. Equipped with super linear bushing A, the LINEAR-SET LSAOE-A-20-DD offers self-alignment capabilities, which enhances its performance by allowing for minor misalignments in mounting without compromising movement accuracy. The inclusion of two external seals provides added protection against contaminants, extending the life of the unit and maintaining its efficiency. With a shaft diameter labeled as size V and an outer diameter designated size H, this linear set ensures compatibility with a range of setups. It also boasts an impressive dynamic load capacity (size H) and static load rating (size M), signifying its ability to handle significant loads while maintaining smooth operation. The unit is capable of maximum acceleration (amax) and can operate within a permissible ambient temperature range from -20°C to 80°C. Its breakaway force (size H) and maximum permissible linear speed (vmax), which can reach up to 5 m/s under specific conditions, indicate its suitability for high-speed applications although service life may be reduced due to increased wear on plastic components. This Bosch Rexroth linear set comes clamped to an h6 shaft lower limit and is set to zero-clearance out of the box, ensuring minimal radial clearance upon installation. For those requiring specific clearance adjustments, an adjusting screw is provided for fine-tuning radial clearance to meet precise application needs. Overall, the LINEAR-SET LSAOE-A-20-DD offers robust construction, precise adjustability, and reliable performance for various industrial motion tasks requiring exacting standards of linearity and repeatability.

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.

	s = travel distance
