KBA-L Linear Bearing Pillow Block Features
The KBA-L long linear bearing housing is a closed, double-length European metric version. The two KB standard linear bearings are mounted in the housing and arranged in a straight line in the aluminum casing. Advantages of the bearing bushing include less tilt or friction, less wear over time, and better machining results.
If you are manufacturing CNC milling machines, milling machines or lathes that require precise linear motion, it is a perfect solution to install this long aluminum bearing housing with KB standard linear bearings. Aluminum housing size range: length (L) ranges 58-230mm (matching KB standard linear bearing length (L) ranges 25-100mm); width (W) ranges 34-122mm; height (F) ranges 22-102mm. The minimum combined size of the specification KBA8L is 58*34*22mm, and the largest combined specification KBA50L is 230*122*102mm. These data are basically the same as the SMA-L extended type linear bearing pillow block
, except that the KBA-L series has no diameter of 12mm and 35mm. The aluminum housing has four CNC drilled holes, threaded holes and countersunk holes of the same size M4-M10, which can be easily and safely mounted to almost any linear motion system.
A typical CNC system consists of a linear shaft of matching diameter, ranging from 8 to 60 mm in diameter, mounted on both ends of the shaft by two end supports, and the housing of the extended linear bearing runs straight along the shaft. Most CNC machines and 3D printers have two such components mounted side-by-side, using a housing as a stand to support the mobile platform. This is a long unit able to be mounted from above or below, making it easy to incorporate into the intended system. Positioning and precision enhancements are facilitated with one of the side aspects serving as datum face. The extruded aluminum case has undergone sufficient post-extrusion heat treatment to create a compact, lightweight and precision item.
