KBB-AJ Linear Bearing Pillow Block

KBB-AJ Linear Bearing Pillow Block
ISUTAMI KBB-AJ adjustment linear bearing pillow block, also known as KBB-AJ adjustment linear bearing unit, KBB-AJ adjustment linear slide unit or KBB-AJ adjustment linear case housing (unit), is suitable for linear motion products in European market. AJ is an abbreviation for adjustment. This model consists of an adjustable aluminum housing with two diagonal fixing holes and a matching KB-AJ clearance-adjustable linear bearing. There is a gap at the top of the unit and a screw and screw hole for adjusting the clearance on one side. There is one circlip on each end. 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 used because it is small and light, and has strong corrosion resistance.

KBB-AJ Linear Bearing Pillow Block Features

The KBB-AJ adjustment linear bearing housing is a single-length European metric version. The KB-AJ adjustment linear bearing is mounted in the housing. KBA-AJ linear bearings are easier to install on linear shafts due to their light adjustment characteristics, saving installation time. The advantage of a linear bushing is cheap to manufacture and used in an infinite stroke. When the loading ball contacts the shaft at a certain point, the bearing capacity of the bearing application is very small. High-precision horizontal movement can be obtained by rotating the ball with very little frictional resistance.

If you are manufacturing a CNC milling machine, milling machine or lathe that requires precise linear motion, it is a perfect solution to install this aluminum bearing housing with KB-AJ linear bearings. Aluminum housing size range: length (L) ranges 43-91mm; width (W) ranges 53-108mm; height (F) ranges 42-90; minimum item KBB16AJ combination size is 43*53*42mm, maximum item KBB40AJ, the combined size is 91*108*90mm. And the product size error is between±0.02mm. These data are consistent with the KBB standard linear bearing pillow block. The aluminum housing has two CNC drilled holes, threaded holes and countersunk holes of the same size from M6 to M12, which can be easily and safely mounted to almost any machine.

A typical CNC system consists of a linear shaft with a diameter of 16-40 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.

KBB-AJ adjustment linear bearing unit is widely used in precision equipment such as electronic equipment, tensile measuring machine and materialized three-dimensional measuring equipment; multi-shafts machine, punching machine, tool grinding machine, automobile cutting machine, printer, card sorting machine, food packaging machine, the sliding part of industrial machinery.
