KBA Linear Bearing Pillow Block

KBA Linear Bearing Pillow Block
ISUTAMI KBA standard linear bearing pillow block, also known as KBA standard linear bearing unit, KBA standard linear slide unit or KBA standard linear case housing (unit), is a product suitable for the Asian and European markets. It consists of a closed standard aluminum housing with 4 fixing holes and a matching KB standard linear bearing. The unit has two circlips. There are also two rubber seals (UU) at both ends of the linear bearing to prevent debris or ball bearing contamination. In addition, the aluminum casing is small and light, and has high corrosion resistance.

KBA Linear Bearing Pillow Block Features

The KBA standard linear housing is a closed, single-length Asian metric version that is fitted with a KB standard linear bearing. The KB closed bearing design allows for cost reduction by using end support shafts. Advantages of the 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 choice to install this aluminum bearing pillow block with a KB standard linear bearing. Aluminum housing size range: length (L) ranges 30-122mm; width (W) ranges 34-132mm; height (F) ranges 22-144; minimum item KBA8, its combination size is 30*34*22mm, maximum item KBA60, the combined size is 122*132*144mm and the product size error is between±0.02mm. These data are the same as the KBA-AJ adjustment linear bearing pillow block. The aluminum housing has four CNC drilled holes, threaded holes and countersunk holes of the same specification M4-M12, 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, mounted on both ends of the shaft by two end supports, and a linear bearing with linear bearings running 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.
