81209 TN – Axial cylindrical roller bearing for easy-to-assemble separating design

Quality that safeguards processes
This axial cylindrical roller bearing accommodates very high axial loads in one direction while running with low friction. The linear contact zone of the rollers ensures defined axial guidance and high stiffness. This results in smooth running conditions with reproducible results, even under varying operating conditions. Therefore, radial loads are not supported and, if necessary, are accommodated by a separate bearing.

Design and manufacturing quality
Cylindrical rollers with linear contact, a dimensionally stable cage made of glass fiber reinforced polyamide (TN), and finely machined raceways keep the frictional torque low and distribute axial forces evenly. The slightly relieved roller ends prevent edge stresses and promote smooth running under load. Furthermore, as a single-row version of the 812 series, it is designed for high axial loads in one direction. The separable design – shaft washer (WS), housing washer (GS), and roller/cage assembly (K) – facilitates assembly, disassembly, and condition testing. At the same time, the angular adjustability is inherently very limited, necessitating careful alignment of the contact surfaces. Additionally, the mating surfaces should be flat, hardened, and finely ground to minimize frictional torque and wear.

Convincing in everyday life
In operation, the combination of high axial stiffness and compact design proves its worth. Finally, a coordinated lubrication and fitting concept ensures performance throughout the entire service life.

Summary
In short: high axial load-bearing capacity, stiff and low friction – for reliable results under axially dominant loads.
