LF / LFN Series – Round Flange Type Linear Ball Bearing

The LF series is our round flange type linear ball bearing, built on a steel ball rolling element + outer ring + retainer structure. The integrated round flange allows the housing to be bolted directly to a mounting plate, so no extra housing block is required. Designed for use with linear shafts, it delivers low-friction linear motion and is dimensionally interchangeable with mainstream LF series products. Available in standard type (LF..UU) and extended type (LF..LUU), covering shaft diameters from 6mm to 50mm.

Key Features

• Round Flange Mounting – Integral flange with bolt holes, mounts directly to a plate without a separate housing
• Assembly Replacement – Direct replacement of existing same-series bearing bodies in customer equipment
• Standard Type (UU) – Standard housing length, suitable for conventional load applications
• Extended Type (LUU) – Extended housing length, significantly improved rigidity and stability
• Double End Seals – UU indicates seals on both ends, keeping dust out and extending service life
• Wide Size Range – Fits shaft diameters from 6mm to 50mm, covering mainstream application requirements
