KBA-S Linear Bearing Pillow Block Features
The KBA-S short linear bearing housing is a closed, single-length European metric version that is fitted with a KB standard linear bearing. Advantages of linear bearing bushings include less tilt or friction, less wear over time, and better machining results. The KBA-S closed bearing design allows for cost reduction by using end support shafts.
If you are manufacturing CNC milling machines, milling machines or lathes that require precise linear motion, it is a perfect solution to install this short aluminum housing with KB standard linear bearings. Aluminum housing size range: length (L) ranges 14.5-69mm (supporting KB standard linear bearing length (L) ranges 25-100mm); width (W) ranges 34-122mm; height (F) ranges 22-102mm. The minimum combined size item SMA8S is 14.5*34*22mm, and the largest combined size item SMA50S is 69*122*102mm. The bearing data is basically the same as the SMA-S short linear bearing
, except that the KBA-S has a diameter of 12mm and bearing housing for 35mm linear bearings. The aluminum housing has two 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, with a diameter range of 8-50 mm, mounted on both ends of the shaft by two end supports, and the housing of the ultra-short linear bearing runs straight along the shaft. Most CNC machines have two such components mounted side-by-side, using a housing as a stand to support the mobile platform. The housing can be mounted from above or below, making it easy to install into the intended system. Positioning and accuracy enhancement are facilitated by being used as a side aspect of the datum. The extruded aluminum housing is subjected to sufficient extrusion and heat treatment to create a compact, lightweight and precision product.
