## Description

Suitable for axis guides with 8 mm threaded rods, it provides stable support and precise alignment in CNC, 3D printer or automation applications. It has an 8 mm internal diameter for quick mounting, robust zinc die-cast housing, encapsulated construction for protection against dust and wear, smooth operation with reduced vibrations.
The KFL08 pillow block bearing is a compact and reliable solution for guiding and supporting 8 mm shafts. It combines a self-aligning ball bearing insert with a robust die-cast zinc housing (zamak), providing smooth, quiet operation and precise alignment even in assemblies where the shaft is not perfectly coaxial. The oval flange with two holes allows quick, perpendicular mounting to the surface with just two M4 screws.
Thanks to its sealed construction, the bearing is protected against dust and contaminants, which extends its service life and reduces maintenance requirements. It is the ideal choice for 3D printers, CNC machines, automation systems, and DIY projects that use threaded rods or 8 mm shafts.
Main features:
Self-aligning ball bearing insert: compensates for small shaft coaxiality deviations.
Die-cast zinc housing, strong and dimensionally stable.
Sealed construction with protection against dust and dirt.
Smooth and quiet operation with reduced vibration.
Simple mounting via oval flange with 2 holes and M4 screws.
Ideal for 8 mm shafts and threaded rods.
