SKF 61822-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 110x140x16mm

The SKF 61822-2RS1 sealed thin-section deep groove ball bearing provides support for large rotating shafts where designers must minimise both housing diameter and bearing width. Its 618 series geometry offers a compact arrangement compared with conventional 60, 62 and 63 series bearings of the same bore. The single row ball design accommodates predominantly radial loading and axial forces in either direction within the bearing's rated capacity. SKF specifies a basic dynamic load rating of 28.1kN and a basic static load rating of 26kN. These figures help engineers assess expected bearing life and load suitability, particularly where the relatively narrow cross-section limits capacity compared with heavier bearing series.

The 2RS1 double rubber contact seals retain factory grease and help restrict dust, moisture and other contaminants from reaching the rolling elements. This is valuable in enclosed equipment where regular lubrication access is limited. SKF lists a sealed limiting speed of 2,600rpm, making contact seal friction and operating temperature important selection considerations. Normal radial internal clearance must be assessed alongside shaft interference fits, housing tolerances and thermal expansion. Because the bearing rings are relatively thin for their diameter, uneven housing support or excessive mounting forces can affect running clearance. Compared with the non-contact sealed 61822-2RZ variant, this design prioritises contact sealing and contamination protection rather than minimum running friction.
