Equivalent to 6819-2RS
The SKF 61819-2RS1 is a large-bore, thin-section deep groove ball bearing designed for rotating equipment where a substantial shaft diameter must be accommodated within a narrow housing. Measuring 95x120x13mm, it offers a radial cross-section of just 12.5mm, making it particularly useful in space-restricted machinery. Rubber contact seals on both sides retain factory grease and help protect the internal raceways against contamination. With normal radial internal clearance and a pressed steel cage, this bearing suits precision rotary assemblies, specialised industrial mechanisms and lightly loaded large-diameter shaft arrangements requiring compact construction.
The SKF 61819-2RS1 sealed thin-section deep groove ball bearing provides rotational support for equipment requiring a 95mm shaft opening without the bulk of a conventional bearing arrangement. Its slender 618 series construction occupies considerably less space than wider 60, 62 or 63 series bearings, allowing a more compact housing where operating loads permit. The single row ball design carries predominantly radial loads while accommodating limited axial forces in either direction. SKF catalogue data gives a basic dynamic load rating of 19.9kN and a sealed limiting speed of 3,000rpm. These specifications help engineers assess bearing life and operating suitability, particularly where the narrow section offers less load capacity than heavier bearing designs.
The 2RS1 double rubber contact seals retain factory grease and help restrict dust, moisture and other contaminants from reaching the rolling elements. This makes the bearing useful in enclosed equipment where routine relubrication would be difficult. Contact sealing introduces additional running friction compared with open or non-contact sealed alternatives, so temperature and continuous operating speed require consideration. Normal radial internal clearance must be assessed alongside shaft interference fits, housing tolerances and thermal expansion. Because the rings are thin relative to their diameter, uneven housing support or excessive mounting pressure can distort the raceways. Accurate alignment and carefully controlled installation are therefore particularly important for this bearing.
Typical Applications:
Large-diameter rotary positioning mechanisms
Space-restricted industrial shaft supports
Precision indexing and automation equipment
Lightly loaded industrial rotary assemblies
Specialised machinery with narrow bearing housings
