KBB Linear Bearing Pillow Block

KBB Linear Bearing Pillow Block
ISUTAMI KBB standard linear bearing pillow block, also known as KBB standard linear bearing unit, KBB standard linear slide unit or KBB standard linear case housing (unit), is a product suitable for the European market. It consists of a closed aluminum housing with 2 diagonal mounting 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.

KBB Linear Bearing Pillow Block Features

The KBB standard linear housing is a closed, single-length European metric version that is fitted with KB standard linear bearing. The KB closed bearing design allows for cost reduction by using end support shafts. KBB linear bearing pillow block, manufactured with low cost, are used in the limitless journey or used to work in the column. As loading ball contacts the shaft at a certain point, the bearing application loading capacity is quite small. By ball's rotating with a quite small friction resistance, high-precise level movement can be obtained.

If you are manufacturing CNC milling machines, milling machines or lathes that require precise linear motion, it is a perfect solution to install this aluminum bearing housing with KB standard linear bearings. Aluminum housing size range: length (L) ranges 43-91mm; width (W) ranges 53-108mm; height (F) ranges 42-90; minimum item KBB16 combination size is 43*53*42mm, maximum item KBB40 combined size is 91*108*90mm and the product size error is between ±0.02mm. The aluminum housing has two CNC drilled holes, threaded holes and countersunk holes of the same size M6-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.

KBB linear bearing units are widely used in precise equipment such as electronic equipment, pull measuring machine, materialization 3-D measuring equipment, etc; and slip part of industrial machines such as multi-shafts machine, punching machine, tool grinder, auto steam cutting machine, printer, card selection machine, food packing machine and so on.
