Product Description
The FAG UK 209 is a radial insert ball bearing designed for mounted bearing units requiring a 40 mm shaft diameter. It features a spherical outer ring, a tapered 1:12 bore and mounting by means of an adapter sleeve. This design enables secure shaft location while allowing straightforward installation and replacement during maintenance, repair and overhaul (MRO).
Unlike insert bearings with eccentric locking collars or grub screws, the UK series is mounted using an adapter sleeve fitted to the tapered bore. This mounting method provides secure positioning on plain shafts without requiring shaft machining and allows easy adjustment during installation.
The spherical outer ring is designed for use with compatible mounted bearing housings. It allows slight self-alignment within the housing and helps compensate for minor shaft misalignment, contributing to stable operation of the complete bearing unit.
The bearing is fitted with RSR contact seals on both sides to help retain lubricant while reducing the ingress of dust, dirt and moisture. A solid polyamide cage accurately guides the rolling elements while minimizing friction and bearing weight. The Black Durotect BS surface coating improves corrosion resistance of the bearing components.
Because of its standardized dimensions and mounting arrangement, the FAG UK 209 is widely used by machine builders, maintenance departments and industrial service companies requiring reliable mounted bearing solutions for rotating shafts.

AI FAQ
Why is a tapered bore used?
It enables secure mounting on a plain shaft by means of an adapter sleeve.
What is the advantage of a spherical outer ring?
It allows proper seating and slight self-alignment within compatible housings.
What should maintenance engineers verify before replacement?
Check the shaft diameter, housing dimensions, adapter sleeve, tapered bore and operating conditions.
What is the purpose of the RSR seals?
They help retain grease while reducing contamination entering the bearing.
Is Black Durotect BS a protective coating?
Yes. It provides additional corrosion protection for the bearing components.
What information should purchasing departments provide when ordering?
Manufacturer (FAG), designation (UK 209) and bearing dimensions (40x85x32 mm).
