The Bosch Rexroth LINEAR-SET LSGF-M-12-DD (R108121200) is a high-quality linear motion system designed for precise and efficient guidance of moving parts in various applications. This linear set is crafted from steel with a flange configuration, integrating a standard LB metal for robust performance. The set includes a flanged housing made of lamellar graphite cast iron, providing excellent durability and resistance to wear. It comes equipped with standard linear bushings that feature wiper seals on both sides to protect against contaminants, ensuring reliable operation even in challenging environments. With a shaft diameter of 12 mm, the LINEAR-SET LSGF-M-12-DD offers two retaining rings and two additional spacer rings made of steel, tailored for compatibility with shaft diameters up to size V. The radial clearance is not adjustable but has been meticulously determined from working bore diameter and shaft tolerance statistics to deliver consistent performance. The set achieves similar radial clearance values as those specified in the hH column under Radial clearance for the R standard linear bushing. This product has been engineered to withstand a maximum acceleration (amax) and offers a permissible ambient temperature range from -20°C to +80°C. It boasts an impressive dynamic load capacity (C), static load rating (C0), and can handle maximum permissible linear speeds (vmax). The friction force (FR) indicates the frictional drags generated by the bushings when not under radial load, which vary depending on speed and lubrication conditions. Weighing in at 0.44 kg, the LINEAR-SET LSGF-M-12-DD is part of Bosch Rexroth's Linear Sets with standard Linear Bushings product group and is particularly suited for vertical shaft designs within its modular unit series. Its size E outer diameter D and breakaway force are designed to meet demanding application requirements while maintaining precision and stability throughout its service life.

Impact of load direction on load rating of closed Linear Bushings

The listed load ratings should be chosen depending on installation in minimum or maximum position and should be based on the calculations. If the load direction is clearly defined and the Linear Bushings can be installed in maximum position, the load ratings Cmax. (dynamic load rating) and C0 max (static load rating) can be used. If aligned installation is not possible or the load direction is not defined, the minimum load ratings must be used.

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 R1066, R1068 and R1072 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.

General mounting instructions

Linear sets with standard Linear Bushings do not come with initial lubrication. Grease the Linear Bushings before use. Service life data is based on initial lubrication and relubricated Linear Bushings.
