Deep Groove Ball Bearings FAG 6206 -RSR

The FAG 6206-RSR deep groove ball bearing (30x62x16 mm) combines single-sided sealing with low frictional resistance for radial loads in mechanical engineering.

The FAG 6206-RSR deep groove ball bearing is a single-row radial ball bearing to tolerance class P0 (ABEC 1). Manufactured from 100Cr6 rolling-bearing steel, this design primarily accommodates radial forces as well as moderate axial forces. With key dimensions of 30 mm inner diameter, 62 mm outer diameter and 16 mm width, the component fits into standardised bearing seats. The integrated sheet steel cage guides the rolling elements at operating temperatures ranging from –30 to +100 degrees Celsius.

What is the 6206-RSR deep-groove ball bearing suitable for in practice?

Design engineers primarily use this ball bearing in mechanical bearing arrangements where one side of the housing is already sealed or oil-lubricated. The single-seal design protects the interior from the ingress of particulate contamination from the sealed side, whilst lubricant can reach the raceways unhindered from the open side. The component therefore serves specifically as a transition between protected assemblies and the environment.

What are the special features of the single-sided RSR seal?

The abiding RSR sealing lip lies directly against the inner ring and protects against the ingress of fine particles from the outside. As only one end face is sealed, less frictional heat is generated during operation than with variants that are sealed on both sides. When designing the system, the installation direction of the sealing disc and the standard radial bearing clearance must be taken into account; these are tailored to standard fits and typical thermal operating conditions.
