The Bosch Rexroth LINEAR-SET LSK-20-DD-NR (R106022020) is a comprehensive linear motion system designed for smooth and precise linear movement applications. This linear set is constructed from plastic with a reinforced PA segmental linear bushing, ensuring lightweight yet stable performance. It features a rust-resistant pillow block housing which provides additional durability for various operational environments. The LSK-20-DD-NR comes equipped with two interchangeable wiper seals that maintain cleanliness by preventing the ingress of contaminants, thus prolonging the system's life and maintaining its efficiency. The radial clearance of the unit is adjustable, allowing for customization to meet specific application requirements, and it is delivered clamped to the shaft's lower limit, set to zero-clearance for immediate use. This linear set boasts a dynamic load capacity (C) and static load rating (C), indicating its ability to withstand forces during operation. The friction force (FR) specified relates to the frictional drags generated by the bushings when not under radial load, which varies depending on speed and lubrication conditions. With a size V for friction force, size H for maximum acceleration (amax), and size E for breakaway force, this product has been designed to cater to varied operational demands. It operates efficiently within a permissible ambient temperature range from -20°C up to 80°C, ensuring reliability across different working conditions. The LINEAR-SET LSK-20-DD-NR also includes a stainless steel bolt, washer, and nut as part of its assembly kit. Its format of closed linear bushings contributes to its robust design. Weighing in at just .5 kg, this product combines lightweight construction with high-performance capabilities making it an optimal choice for applications requiring precise linear guidance without excessive bulk or weight.

Effect of load direction on load rating

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.

Reduced load capacity with short stroke

In case of a short stroke, the service life of the shaft is less than that of the segmental Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .

Selection guide for operation under difficult conditions

For constantly humid or damp conditions caused, for instance, by water-based coolants/lubricants, we recommend the stainless steel Linear Bushing with parts made of steel in accordance with ISO 683-17 / EN 10088.

Life expectancy calculation

General mounting instructions

Linear sets with segmental 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.
