Deep Groove Ball Bearings FAG 62310 -2RSR

The 62310 -2RSR deep groove ball bearing from FAG Rolling Bearings, with dimensions of 50x110x40 mm and sealing rings on both sides, provides protection against the ingress of dirt.

This single-row deep groove ball bearing 62310 -2RSR is primarily designed to accommodate radial loads as well as moderate axial loads. Manufactured from standard rolling bearing steel 100Cr6, this version features a robust sheet steel cage. A key advantage lies in the seals on both sides: the abutting sealing lips keep out dust and moisture and retain the factory-applied lubricant within the bearing housing.

What operational requirements does the 62310 -2RSR deep groove ball bearing meet?

This design is suitable for shaft mountings where high load-carrying capacity and sealed systems are required. As the outer ring has no flange or groove, the bearing can be fitted directly into cylindrical housing bores. The permissible temperature range of –20 to +100 degrees Celsius covers typical industrial environments. This eliminates the need for additional external sealing elements at the bearing locations.

What criteria are important for bearing clearance and sealing?

The 62310 -2RSR design features standard radial bearing clearance and tolerance class P0/PN (corresponding to ABEC 1). This ensures balanced running behaviour during normal operation with standard fits. It should be noted that seals which make contact on both sides generate slightly more frictional heat than non-contacting cover plates, due to the contact between the seal lips. Before installation, the shaft diameter of 50 mm and the housing bore of 110 mm must be matched.
