The Bosch Rexroth LINEAR-SET LSSOE-B-12-DD (R106881240) is a high-quality linear motion set designed for precision applications. This linear set is made from steel and features an open, adjustable design with a standard precision housing crafted from spheroidal graphite cast iron. The set includes a super linear bushing B, which lacks a self-alignment feature, ensuring stable and precise motion. Integrated wiper seals on both sides of the bushing protect against contamination and maintain the system's integrity. With a shaft diameter of d and secured with a locating screw, this Bosch Rexroth linear set ensures robust attachment and reliable operation. The outer diameter D of the set allows for compatibility with various installations. It is capable of handling dynamic load capacities (noted as C in specifications) efficiently, which applies to the main direction of loading. The static load rating C also indicates its ability to withstand loads without movement. This linear set can operate within an ambient temperature range from -20°C to +80°C, making it suitable for diverse working environments. It has been tested for total travel distances significantly exceeding standard requirements without failure, showcasing its durability and longevity. The LINEAR-SET LSSOE-B-12-DD comes clamped to the h shaft's lower limit and is pre-set to zero-clearance for immediate use in applications requiring precise guidance without play. An adjusting screw allows for fine-tuning of radial clearance if necessary. The product's weight stands at 0.5 kg, indicating its solid build yet manageable handling characteristics. Overall, this Bosch Rexroth product is designed to deliver reliable performance in linear motion applications where precision and durability are paramount. Its robust construction and thoughtful features make it suitable for use in various settings where accuracy and long service life are required.

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.

 

Bolts

We recommend bolts in accordance with ISO 4762-8.8 for fastening the Linear Sets.
