KBB-OP Linear Bearing Pillow Block

KBB-OP Linear Bearing Pillow Block
ISUTAMI KBB-OP open linear bearing pillow block, also known as KBB-OP open linear bearing unit, KBB-OP open linear slide unit or KBB-OP open linear case housing (unit), is suitable for Europe market. OP is an abbreviation for open. This model consists of an open aluminum housing with two diagonal fixing holes and a matching KB-OP open linear bearing. Each end of the unit has a circlip. 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-OP Linear Bearing Pillow Block Features

KBB-OP open linear bearing housing is a single length European metric version. The KB-OP open linear bearing is mounted inside the casing. And the advantages of a linear bushing is inexpensive to manufacture and used in an infinite travel. 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 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 open linear bearing. Aluminum housing size range: length (L) ranges 43-91mm; width (W) ranges 53-108mm; height (F) ranges 35-77mm; minimum item KBB16OP combination size is 43*53*35mm, maximum item KBB40OP combined size is 91*108*77mm and the product size error is between±0.02mm. The length and width are the same as the KBB standard linear bearing pillow block as well as KBB-AJ adjustment linear bearing pillow block of the same specification. The aluminum housing has two CNC drilled holes, threaded holes and countersunk holes of the same size M6-M12.

The typical CNC system includes the matching SBR shaft rail, the linear bearing opening angle (θ) ranges from 50° to 78°, and the diameter ranges from 16 to 40 mm. The open bearing housing opening is oriented toward the shaft fulcrum base. Each end fits in, and the bearing housing with linear bearing runs 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. Positioning and accuracy enhancement is facilitated by being used as a side aspect of the datum.
