Linear ball bearing SKF LBCR 20 D-2LS 20x32x45

Аналоги lbcr 20, lbcr 20 a-2ls, lbcr 20-2ls Linear ball bearings of the improved cylindrical design LBCR consist of a segmented separator, raceways for directing balls, protective seals or covers. Due to their extremely long raceways and the ability to mechanically deform the rolling, they are capable of withstanding heavy loads. The two-leaf LS seal ensures trouble-free operation without pre-lubrication for pre-lubricated bearings that operate under standard conditions. The integral seal is specially designed for linear operations. These seals have also been optimized and refer to low friction seals. Sealing jaws maintain full contact with the shaft, while offering an excellent sealing solution even when used with the linear bearing shaft of the LBC series. Linear ball bearings LBCR with their optimized segments of the raceways and having the maximum load capacity, can be installed both in a closed and in an adjustable casing. When these bearings are installed in a closed housing, tolerances for the inscribed diameter of the ball system and, therefore, the working clearance are determined by the tolerance of the opening in the housing. When installed in slit casings, linear guides can be adjusted to provide working clearance or preload, depending on the needs of the application. Linear ball bearings LBCR should be located in the axial direction, for example, through a grease or a fixing pin.
