KFL08 8mm Zinc Alloy Flange Bearing Housing – Diamond Pillow Block Shaft Support for 3D Printer & CNC

Overview 

The KFL08 (FL08) 8mm Flange Block Mounted Bearing is a compact, self-aligning shaft support designed for precision mechanical assemblies. Cast from a rugged, lightweight zinc-aluminum alloy, this housing contains a pre-lubricated deep groove steel ball bearing insert.

The inner ring of the bearing features an extended collar equipped with two hex socket grub screws, allowing you to lock the bearing tightly onto any standard 8mm optical axis or T8 lead screw. Its specialized diamond-shaped flange design is optimized for space-constrained installations where mounting perpendicular to a flat structural plate or sheet metal wall is required.

Key Features 

• Self-Aligning Design: The insert bearing features a spherical outer surface that matches a curved internal housing seat, allowing the bearing to swivel smoothly to compensate for minor framework misalignments without binding.

• Dual Locking Grub Screws: Integrated set screws on the extended inner ring bite firmly into your 8mm guide rod to prevent axial sliding or slippage under load.

• Low Profile Diamond Flange: Two-bolt flange design takes up minimal real estate compared to standard 4-bolt square housings, ideal for tight 3D printer frame corners.

• Ready-to-Install: Factory sealed and pre-packed with heavy-duty industrial bearing grease for maintenance-free, silent operation.

Technical Specifications

KP08 vs. KFL08 Layout Check

• KP08 (Pillow Block): Mounts flat on top of a horizontal plane (screws point downwards into a table or base shelf).

• KFL08 (Flange Block – This item): Mounts flush against a wall or panel face (screws point horizontally into a side support wall or top lid).
