Deep Groove Ball Bearings FAG 6207 -RSR

The FAG 6207-RSR deep-groove ball bearing, with dimensions of 35 × 72 × 17 mm and a single-sided sliding seal, offers effective protection whilst maintaining low frictional resistance.

The 6207-RSR deep groove ball bearing is designed as a single-row radial ball bearing made from 100Cr6 rolling bearing steel. The manufacturer, FAG, produces this version to the standardised tolerance class P0/PN, which corresponds to ABEC 1, and fits it with a sheet steel cage. The design primarily accommodates radial forces, but is also suitable for handling moderate axial loads in both directions. Thanks to the standard radial clearance, the bearing operates under standard operating conditions without any unusual thermal expansion of the bearing rings.

In which installation situations is the 6207-RSR deep groove ball bearing used?

Applications can be found in general mechanical engineering for shaft mountings where contamination is only present on one side. Designs utilise this configuration where the housing is already sealed or closed on one side, whilst the opposite side requires a barrier against dust and dirt particles. The open side of the bearing also allows the component to be connected directly to a lubrication system or for lubricant to be replenished from the outside. The operating temperature range is specified as -30 to +100 degrees Celsius.

What design features characterise the single-sided RSR seal?

The designation RSR stands for a single-sided, integrated sliding seal. This lip contacts the inner ring and shields the rolling elements from fine particles and splash water. Compared with double-sealed designs, the single-sided sealing contact reduces friction losses and heat generation during operation. During assembly, the sealed side must face the contaminated area. Thanks to the cylindrical outer ring without a flange or groove, the bearing can be pressed directly into a straight housing bore.
