The Bosch Rexroth LINEAR-SET LSAOE-B-12-DD (R103881220) is a linear motion set designed for precision applications requiring smooth and accurate guidance. This product features a lightweight precision housing made of aluminum and incorporates a super linear bushing B without self-alignment capabilities. The linear set is open and adjustable, allowing for fine-tuning to specific application requirements. Equipped with two seals, the LINEAR-SET ensures protection against contaminants, contributing to its reliability and longevity in various operating environments. The inclusion of external seals and the ability to relubricate further enhance its durability. The shaft diameter is designed to accommodate standard sizes, while the grooved taper pin secures the bushing in place. The product boasts impressive mechanical specifications, including a high dynamic load capacity, which ensures it can handle significant forces during operation. It also has a notable static load rating, providing stability under stationary loads. The LINEAR-SET can achieve maximum acceleration and operate within a wide range of ambient temperatures without compromising performance. With a breakaway force designed for size H and the ability to reach a maximum permissible linear speed, this linear set is suitable for high-speed applications. It has been tested to endure substantial total travel distances without failure, indicating robustness and reliability over time. For applications that demand precise control over radial clearance, this LINEAR-SET comes clamped to an h6 shaft lower limit and set to zero-clearance out of the box. An adjusting screw facilitates fine adjustments for zero-clearance or preloaded guides. Overall, the Bosch Rexroth LINEAR-SET LSAOE-B-12-DD (R103881220) represents an advanced solution for linear motion applications where precision, adjustability, and long service life are paramount. Its construction and features make it well-suited for use in various industrial settings where accuracy and repeatability are critical.

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.
